Full textAbstract:
For 20 years, and more intensively during the last decade, indigenous knowledge has challenged the regime of intellectual property. If this field of law has been, in the past, challenged by new technology, it is now, with the problematic of indigenous medicinal knowledge, put to the test by "old invention". The present thesis examines the status of indigenous medicinal knowledge in international intellectual property law. Thus, we will proceed to the study of the main international conventions and the common regime of intellectual property law in order to determine the treatment accorded to medicinal indigenous knowledge within the actual system. The role that intellectual property could play in the future will also be examined.

Full textAbstract:
This dissertation consisting of three case studies, examines how the intersection of biomedicine and indigenous medicine in South Africa has formed and reformed indigenous medical practice over the past century. South Africa, like many other countries, has emerged from colonialism with the need to reassert its indigenous practices. In the case of medicine, this reformation is of particular importance because the last several decades have seen the development of the HIV/AIDS pandemic. Yet the contemporary discourses and policies surrounding indigenous medicine have much in common with their colonial predecessors. This research is interested in the way medicine has been constituted in a post-colonial context. In particular, how has the intersection of indigenous and biomedicine reconfigured and respatialized medicine in South Africa?The ways the colonial government acted to regulate indigenous medicine in essence simplified the practice and divided it into subcategories- `natural' medicine (e.g. herbs), `modern' medicine (e.g. stethoscopes) and `supernatural,' (e.g. throwing bones). The natural was the only category of practice legal in the country. Even as the government structure changed, and the previously disadvantaged eventually came to lead the country, these categories still persisted. As such, when a crisis like HIV/AIDS strikes and the need to enroll the help of the indigenous healers becomes clear, calls for their regulation, as a way to gain their assistance, are made. Although the current call does not aim to limit the number of healers, there are similar public health goals of rooting out the `bad' indigenous healers.Overall three major findings emerged: First, colonial regulations are re-introduced in a post-colonial context as discourses, which are then reinstated as policies; second, policy over the past century tends to view indigenous medicine in a simplified form (i.e. as plant-based and natural); and third, there is a constant tension between biomedicine and indigenous medicine where biomedicine works to extend its spaces of practice into the indigenous realm.

Full textAbstract:
This study aims to identify traditional medicines which people use in Babati District, Tanzania and to find out which direction the local use and knowledge of traditional medicine is taking in comparison with modern medicine (MM). It is a case study based both on primary and secondary sources. The primary information was gathered with the help of semi-structured interviews and shorter enquiries with people of all categories that use herbal remedies or visit bone fixers and with women that are supported by traditional midwifes. For simple health problems people use TM, for more complicated cases, they go to the hospital. A difference between Babati urban and rural inhabitants was noticed in the usage of traditional and modern medicine, but not between poor and rich people, opinions being slightly different. The Tanzanian government does not encourage the implementation of the TM in the modern medical system and as long as the young generation is not interested to learn the secrets of their parents‟ vocation, this knowledge is threatened by being forgotten. All the herbs used in TM will most likely find their way into the modern pharmacy; however because of the lack of documentation and statistics, it can take up to one hundred years. For this purpose, the gap between TM and MM has to narrow through a better collaboration between all the involved parts.

Full textAbstract:
Chinese medicine is one of China's key national assets, an indigenous medical knowledge and practices that serves Chinese for thousands of years. As very little research has been focused on Traditional Chinese Medicine (TCM) from systems of innovation perspective, the topic of study was chosen. This qualitative case study research introduces, defines and explores how TCM organisations collaborate to innovate from an evolutionary, interactive system perspective. In particular, the focus is on the development of knowledge and capabilities related to TCM drug research and production. Thirty one TCM organisation cases were analysed and presented in this study, interpreting their behaviour in terms of ideas drawn mainly from the literatures on systems of innovation, collaboration between organisations and resource (knowledge) based theory of the firm. Actors such as government play various roles in facilitating organisational and sectoral innovation processes. 'Various policy instruments', in particular research funding and institutions (e.g., standards and regulations) were used to enhance innovation and production. Various forms of collaborative networks were found among key actors: enterprises, universities, research organisations and end users. They contribute to the active innovation processes of 'Identification, Selection, Integration and Creation' of tangible and intangible outcomes and changes. Based on the research, new insights were derived as to how indigenous resources (defined as original and/or traditional knowledge and capabilities) may lead to indigenous innovation. This thesis contributes to the academic understanding of systems of innovation operating in the context of indigenous product and related process developments with reference to various actors interplaying in complex networks (systems) of collaborations. New understandings made on the processes of indigenous innovation (using TCM as a case) through investigating the actors' roles, inter-relations and their restless attempts to identify opportunities and problems, select and integrate different indigenous, scientific, technological and managerial knowledge, capabilities, resources and institutions, to create value that may 'fit' in evolutionary terms, the demand of the key actors in the sector.

Full textAbstract:
>Magister Scientiae - MScThis study sought to identify the bottlenecks in the promotion of Zimbabwean Traditional Medicines (ZTMs) towards improving the national healthcare delivery system. The indigenous medicines lost value and recognition to the Conventional Western Medicines introduced by the British colonialist since 1871 and is still dominating the national healthcare delivery system. There are growing challenges to ensure accessibility of affordable drugs especially for primary healthcare. The World Health Organization (WHO) and United Nations (UN) is in support of re-engaging indigenous medical interventions to achieve the Millennium development goals. Indigenous Traditional Medicine Knowledge-Based Systems (ITMKS) form the basis of the main source of health care for about 80% of the population in the developing countries. The implementation of the Zimbabwe Traditional Medicines Policy (ZTMP) has been at a stand-still since inception in 2007. The research used mixed methods involving qualitative and quantitative approaches. Data was collected through desk and field research. Questionnaires and focus group discussions were used to record perceptions and attitudes of key informants. The stakeholders included Traditional Health Practitioners (THPs), Medical Doctors, Pharmacists, Medical Research Council of Zimbabwe (MRCZ) staff, Medicines Control Authority of Zimbabwe (MCAZ), Traditional Medical Practitioner’s Council (TMPC), Zimbabwe National Traditional Healers Association (Zinatha), Ministry of Health and Childcare, WHO, Higher Education Institutions (UZ School of Pharmacy staff and students), Christian Groups, NGOs and Prostate Cancer Patients in Harare CBD. The stakeholders sampling framework was obtained from the list of registered practitioners. The stakeholder mapping involved selection of 5 key informants from each focus group obtained through random selection. The Snowball sampling technique was used to follow the closest 5 key informants in each focus group. The key findings established that 80% of respondents agreed to the integration of ZTM. The major bottlenecks were lack of modern dosage forms and standardization to determine quality, safety and efficacy of the ZTM. The study suggests that in order to fast track the integration process, a bottom up implementation strategy providing ZTM advocacy, capacity building in the institutionalization and training of ZTMPs, pharmacists and CMP need to be engaged for a favorable and quick buy-in. The study also recommends further analysis of the Indigenous Knowledge Systems (IKS) areas of specialization in pharmaceutical practice in order to improve treatment outcomes.

Full textAbstract:
The incidence of Type 2 Diabetes Mellittus (T2DM) is increasing world wide. In Africa the limited access to health care and the insidious course of the disease lead to more severe illness and diabetic complications. There is a need to find alternative approaches to treatment and prevention that address the problems and needs of Africa. Sutherlandia frutescens (S.frutescens) is a traditional herbal plant with known anti-diabetic properties, the precise mechanism of action of S.frutescens is not known. In order to develop new approaches for treatment and prevention of T2DM the pathophysiology of T2DM must be understood. T2DM is the final outcome of a multi-organ disease characterized by early defects in muscle, adipocytes, hepatocytes and pancreatic β-cells. In this study the role of the liver was investigated because of its central role in glucose and lipid metabolism. It is hard to differentiate between all the influences in an in vivo model, so the aim of this study was to develop an in vitro model of T2DM in Chang liver cells and to determine if S.frutescens can reverse the state of insulin resistance in this model. Different culture media conditions were screened to identify a method that can be used as the T2DM model in Chang liver cells. Serum free medium (MCBD-201) supplemented with human diabetic serum, (2.5%-10%), high insulin concentrations (0.1μM-1μM), high fructose concentrations (1-10mM). and a combination of high insulin and high fructose was used for this screening. Chang liver cells cultured in MCBD-201 medium supplemented with 1mM fructose and 0.1μM insulin showed reduced glucose uptake and increased lipid accumulation. The effect of two S.frutescens extracts, two anti-diabetic drugs, metformin and ciglitazone, and a hypolipidemic drug ciprofibrate were determined and shown to increase glucose uptake and reduce lipid accumulation. It was postulated that exposing the cells to excess nutrients in the form of high fructose would stimulate the cells to become adipogenic and accumulate lipids, which would interfere with the glucose uptake and induce insulin resistance. Gene expression of PPARγ, PPARα, and SREBP-1 transcription factors regulating lipid metabolism was determined in Chang liver cells cultured in insulin resistance inducing medium over a 48 hour time course. The expression of PPARγ, known to stimulate adipogenesis was increased after 6, 24 and 48 hours of exposure (P(H1)<0.0001). The expression of PPARα, known to stimulate β-oxidation expression, was significantly decreased after 24 hours of exposure (P(H1)<0.0001). The presence of the plant extracts in the insulin resistance inducing media protect against this increase in adipogenesis and decrease in β-oxidation after 48 hours of exposure by increasing PPARα expression and decreasing PPARγ expression. A PCR Array was performed which identified 32 more potential molecular targets of S.frutescens. Five of the 32 targets identified with the PCR Array were validated using qRT-PCR. These genes play a role in lipid and glucose metabolism and protection against oxidative stress and inflammation. In summary a cellular model of insulin resistace in hepatocytes has been established and the capacity of S.frutescens to reverse this process has been demonstrated by acting as a dual PPARγ/α agonist. New genes have been identified in the development of insulin resistance and as targets of S.frutescens.

Full textAbstract:
This thesis examines how traditional medicine workshops offered by an Aboriginal health centre contribute to capacity re-building through self-care in two local communities in Manitoulin Island, Ontario. Health disparities that exist between Aboriginal people and the rest of the population have prompted a need to better understand health determinants that are of relevance in these communities including the importance of culture, tradition, and self-determination. A variety of qualitative methods were employed in this work including in-depth interviews, focus groups and “art voice.” The use of art voice on Manitoulin Island advances decolonizing methodologies by emphasizing how the incorporation of locally and culturally relevant methods or “methods-in-place,” is an effective way to engage communities in the research process. Results show the need to approach traditional teachings, health programs, and research from an Aboriginal worldview and indicate that more frequent workshops are required to empower youth and adults to practice and share traditional knowledge. Furthermore, a continuum exists in which the interest in language, culture, and tradition increases with age. Capacity can therefore be re-built over time within communities promoting autonomy and self-determination through self-care. Findings can be expected to further inform the traditional programming in participating communities, enhance existing Aboriginal determinants of health models by including traditional medicine as an element of self-care, and can act as a springboard for the inclusion of unique place-based methods into community-based research projects in the future.

Full textAbstract:
Carissa lanceolata (conkerberry) is a perennial woody shrub used in traditional medicine by indigenous communities in Western Australia, the Northern Territory and Queensland for various medical conditions such as toothache, respiratory infections and the cleaning of sores, which all strongly indicate an antibacterial activity. A literature review revealed that the wood of this plant possesses significant antibacterial activity, which was found to be related to the presence of eudesmane type sesquiterpenes. C. edulis and C. carandus are frequently used in other traditional systems of medicine in different parts of the world, and thus have also been investigated for bioactive compounds and pharmacological properties. Some of these were found to be in line with the main findings of this work. Carissa lanceolata root was shown to exhibit significant antibacterial activity against both Gram negative and Gram positive organisms. A micro-broth dilution assay was performed on 96-well plates using resazurin as an indicator for microbial growth of Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis and Staphylococcus aureus. Bioassays carried out in this work showed that crude extracts of root bark and wood, particularly their polar constituents were more active against the four strains of bacteria tested.Chemical investigation of the root bark revealed that it contains a volatile oil, which was isolated by steam distillation as well as solid phase micro extraction. It was found to consist of a single compound, which was identified as 2'-hydroxy acetophenone. The identity of this compound was confirmed by GC/MS and 1H NMR spectroscopy. Furthermore, the eudesmane-type sesquiterpene, carissone, was isolated from the root bark DCM and root wood hexane extracts. Its chemical identity was confirmed by IR, 1 [superscript] H and 13 [superscript] C NMR spectroscopy. The lignan, carinol, on the other hand, was isolated from the moderately polar fractions of the root wood MeOH extract. The obtained IR and 1 [superscript] H NMR data as well as Rf values all correspond to the literature. Two other yet unidentified compounds were isolated, but further studies into their chemistry and antibacterial activity were not possible in this current study. The antibacterial activity of the isolated compounds was considerable, with 2'-hydroxy acetophenone exhibiting the strongest effect, followed by carinol and then carissone.

Full textAbstract:
Indigenous Australians were also known to use plants for medicinal purposes. For thousands of years, Indigenous Australians have used native plants as a source of medicinal agents. Some tribes living in Central Australia still, to this day, prefer to use traditional medicines in favour of the more common and readily available western medicines. A number of plant species endemic to Australia are listed in various Aboriginal pharmacopoeias, with approximately one-third of those species belonging to two genera, Acacia and Eremophila. Of the 1100 recognised species of Acacia, approximately 900 occur in Australia. At least thirty of these species were utilised by the Indigenous Australians as a source of medicine. Extracts of 8 Acacia species were screened using four frontline bioassays. These were the brine shrimp lethality test, the crown gall tumour assays, the disc diffusion antibiotic assay and the seed germination test to determine if any of the species were biologically active. Of all the species screened, Acacia pruinocarpa showed the most promise. The species demonstrated significant activity at concentrations at low as 3.7ppm, which is well below the standard 400ppm exhibited by potassium dichromate (Sam, 1993). Acacia adsurgens and A. dictophleba were the next two promising species exhibiting activity at concentrations of 16.12ppm and 37ppm respectively. This was a trend that was also observed in the Lettuce seed germination test for allelopathy with these three species showing the most promise. Interestingly the potency of A. pruinocarpa extract decreased significantly when it was re- screened after being put through a polyamide column. It can therefore be suggested that as tannins are removed by the polyamide column, the biological activity exhibited by A. pruinocarpa is a result of the tannin content in the species (2%), although more testing is required.Both A. pruinocarpa and A. adsurgens showed promise as anti-tumour activity when used in the Crown Gall Tumour Assay (CGTA). Acacia pruinocarpa and A. adsurgens both exhibited significant activity when compared to the control producing inhibition percentages of 31% and 37% respectively. Surprisingly, only one of the Acacia species tested inhibited pathogenic growth when tested on the common pathogens Staphylococcus aureus, Streptococcus pyogens and Candida albicans. Acacia bivenosa was the only species to exhibit any activity when tested on the pathogens. This activity, however is not considered to be significant, as the species was only active against one of pathogens tested, Staphylococcus aureus. In order to be considered to be significant, a species must be active against two or more pathogens. It is however, worthy of further evaluation. Acacia species are among the large number of plants that have long been regarded sources of biological activity. This study was guided by the indigenous use of Acacia species as sources of medicine, which led to the use of front-line bioassays. All of the species tested exhibited some form of biological activity. Acacia pruinocarpa demonstrated the most promise as a source of novel biologically active compounds exhibiting activity at very low concentrations. Such compounds have not been determined as it was outside the scope of this study to identify the active constituents of this species. However, it has been suggested that tannins are responsible for eliciting some of the activity observed in A. pruinocarpa. All of the species screened in this study are worthy of further evaluation. The bioassays used in this study are good examples of front-line bioassays. All of the tests used in the study fulfil the criterion, which defines a good test.

Full textAbstract:
Thesis (M.CUR.) -- University of Limpopo, 2014Indigenous practices (IPs) are experiences generated by people who are living in a specific region context and a specific cultured group. IPs are shaped by cultural traits that are passed from one generation to the next. The practices are rooted and embedded in such a society and, therefore, the practices become part of the people’s lifestyle. It is difficult to try and change these practices, since people have adhered to them throughout their entire lives. The believe system plays a major role in health care seeking behaviour of individuals because they are informed by the IPs that are observed in their environment (Shaik & Hatcher, 2005). IPs are stored in people’s memories and are expressed in songs, dances, beliefs, rituals, cultural values, myths, and healing of diseases by using herbs. During pregnancy, IPs are still applied worldwide. Ayaz and Efe (2008) indicate that it occurs mostly in Turkey and Africa where women’s reassurance is depending on the local context and meaning of pregnancy. THE PURPOSE OF THE STUDY To determine indigenous practices of pregnant women at the Dilokong Hospital in the Greater Tubatse Municipality of the Limpopo Province.This was achieved by the exploring and describing the indigenous practices of pregnant women in the antenatal (ANC) clinic of the maternity ward at the Dilokong Hospital.. DESIGN AND METHOD A qualitative, descriptive, explorative and contextual research design was used for the participants to describe the indigenous practices by pregnant women. Data was collected by means of unstructured one-on-one interviews in maternity unit of the ANC clinic at the Dilokong Hospital of the Greater Tubatse Municipality. Ethical considerations as described by Denosa (2000) were adhered to in order to ensure the v quality of the study. The criteria for trustworthiness were observed as stipulated in Babbie and Mouton (2009).Fifteen pregnant women were interviewed. FINDINGS AND RECOMMENDATIONS Four themes with sub-themes emerged from the data analysis by using Tech’ṡ open coding approach (Creswell 2006, Botma, Greef, Mulaudzi & Wright, 2010). Four themes were emerged namely; indigenous practices based on ancestral knowledge; indigenous practices based on spiritual diviners versus church principles; restricted practices versus instructions followed during pregnancy and labour and indigenous practices during labour and delivery. It is recommended that a national IP strategy needs to be developed to provide a framework and platform to support and promote grass roots IPs into mainstream development in the health care system in relation to midwifery practice. CONCLUSION The study findings indicated that IPs were regarded as an honourable health intervention by THPs, families, and pregnant women. They showed trust in methods used to preserve pregnancy, labour, and delivery, although, the indigenous practices by pregnant women still continue. Indigenous practices such as cords around their waists, are still observed during physical examinations. However, there is a reduction of prescribed potions mixed with cool drinks for use to accelerate labour and to prevent negative consequences because the potential toxicity has been explained during the provision of health education. These findings call for health care professionals to emphasise training and workshops for the THPs church diviners that are the fundamental principle of effective implementation of IPs to enhance improvement in the prevention of complications during pregnancy, labour and delivery.

Full textAbstract:
Tuberculosis (TB) still remains a health problem globally with over a million new infections and a mortality rate of 1.5 million individuals annually (Hawn et al., 2014). The emerging multi-drug resistant (MDR) strains that accompany human immune deficiency virus (HIV) infection in high-incidence populations contribute significantly to the health burden of TB (Areeshi et al., 2014). The standard treatment that is advocated by the World Health Organization (WHO) for active tuberculosis includes long-term therapy that incorporates the use of isoniazid, rifampicin, pyrazinimide and ethambutol as front line drugs (WHO, 2013). Drug resistance against established treatment options for TB makes research into new forms of therapy an imperative in health care (Ntulela et al., 2009). South Africa is currently witnessing a high number of cases of drug-resistant TB. In some parts of the country, one in ten cases of TB is resistant to treatment. It is therefore essential to have new anti-tuberculosis agents, which can be readily and simply produced from some local source (Warner et al., 2014). A logical starting point for this research of new agents would be the herbal medicines which have been used for centuries in rural areas by local healers. Western developed countries have harvested ethno botanical knowledge and have produced drug therapies for conventional medicines for other ailments. The activity of extracts of the active plants and their properties still require study in animal models in order to assess their future as new anti-tuberculosis agents (Lall and Meyer, 1999). This study focuses on qualitative and quantitative experimental findings after the administration of a medicinal plant extract to animals. This will include daily observation of animals, recording of feed consumption, recording of animal weights, macroscopic examination of animals at necropsy, tissue harvesting, histological procedures and microscopy.

Full textAbstract:
Thesis (M.Dev.) --University of Limpopo, 2012The main aim or purpose of this study was to look at the ways and the strategies of minimizing\ mitigating the over-harvesting of indigenous medicinal plants in order to use them sustainably. The task of identifying and assessing challenges facing local communities in utilizing and sustaining indigenous medicinal plants in Thengwe village and their implications on environmental conservation and management of natural resources was done during the pilot survey. The environmental field survey was conducted after gaining permission to enter into the identified study areas including the Mutavhatsindi Nature Reserve. The result revealed that most of the indigenous medicinal plants are used for healing, religious, economical and for protection purposes. Most of the indigenous medicinal plants in the study area are depleted and many of them are facing extinction. The study was qualitative in design. Semi-structured interviews and a questionnaire were used. The questionnaire had both open-ended and closed questions. The study area was Thengwe Village in the Mutale Municipality. The existence of medicinal plants is threatened by people `s perceptions and attitudes towards them. For some indigenous medicinal plants, depletion is at a high rate due to over-harvesting and because the plants when traded by herbalists they have a premium price attached to them. Interestingly, perhaps surprisingly, the majority of young people hold negative attitudes towards the indigenous medicinal plants due to poor knowledge of the value of indigenous medicinal plants, in contrast to the elders who appreciate their role and consider them as part of their culture, economy and religion. One of the findings is that medicinal plants were found to be important to the community members as the source of income and creation of jobs for the medicinal collectors who sell the species to traditional healers. For the reason of preserving indigenous medicinal plants and others as the environmental resources, this study recommends that there should be strong intergovernmental relationships between the National, Provincial and Local governments in order to prevent over-harvesting of the medicinal plants. The indigenous medicinal plants are equally important to biodiversity students and researchers who want to study and research indigenous medicinal plants which play an important role in the improvement of the livelihoods of community members. Furthermore, education campaigns within the communities and school learners are recommended to encourage the prevention, sustainability and utilization of the indigenous medicinal plants. Additionally, the legal authorities should be empowered to prosecute all people who may be found illegally in possession of indigenous medicinal plants, as well as endangered and protected species. Heavy fines and charges should be imposed on such culprits. Of importance is the fact that the results and recommendations of this study may facilitate the teaching of environmental education and management of natural resources as well as boost the local economy of the Vhembe district Municipality by showing that medicinal plants in the area can be seen as a viable tourist attraction.

Full textAbstract:
Doctor of PhilosophyThis thesis analyses the concept of indigenous peoples’ right to self–determination within the international human rights system and explores viable avenues for the fulfilment of indigenous claims to self–determination through the design, implementation and evaluation of development policies. The thesis argues that development policy plays a crucial role in determining the level of enjoyment of self–determination for indigenous peoples. Development policy can offer an avenue to bypass nation states’ political unwillingness to recognize and promote indigenous peoples’ right to self–determination, when adequate principles and criteria are embedded in the whole policy process. The theoretical foundations of the thesis are drawn from two different areas of scholarship: indigenous human rights discourse and development economics. The indigenous human rights discourse provides the articulation of the debate concerning the concept of indigenous self–determination, whereas development economics is the field within which Amartya Sen’s capability approach is adopted as a theoretical framework of thought to explore the interface between indigenous rights and development policy. Foundational concepts of the capability approach will be adopted to construct a normative system and a practical methodological approach to interpret and implement indigenous peoples’ right to self–determination. In brief, the thesis brings together two bodies of knowledge and amalgamates foundational theoretical underpinnings of both to construct a normative and practical framework. At the normative level, the thesis offers a conceptual apparatus that allows us to identify an indigenous capability rights–based normative framework that encapsulates the essence of the principle of indigenous self–determination. At the practical level, the normative framework enables a methodological approach to indigenous development policies that serves as a vehicle for the fulfilment of indigenous aspirations for self–determination. This thesis analyses Australia’s health policy for Aboriginal and Torres Strait Islander peoples as an example to explore the application of the proposed normative and practical framework. The assessment of Australia’s health policy for Indigenous Australians against the proposed normative framework and methodological approach to development policy, allows us to identify a significant vacuum: the omission of Aboriginal traditional medicine in national health policy frameworks and, as a result, the devaluing and relative demise of Aboriginal traditional healing practices and traditional healers.

Full textAbstract:
This dissertation explores discourses about culture and illness in the talk of mental health professionals and indigenous healers. It represents an attempt to situate the issue of indigenous healing in South Africa within a particular strand of critical discourse analytic research. In the context of current deliberations on the value, or otherwise, of indigenous healing in a changing health and specifically mental health system, the talk of both mental health practitioners and indigenous healers as they conceptualise “disorder”, and discuss possibilities for collaboration, is chosen as a specific focus for this study. Disputes over what constitutes “disorder” both within mental health, and between mental health and indigenous healing are an important site in which the negotiation of power relations between mental health professionals and indigenous healers is played out. The results of this study suggest that despite the construction of cogent commendations for the inclusion of indigenous healing in mental health, it remains largely marginalised within talk about mental health practice. While this study reproduces to some extent the marginalisation of indigenous healing discourse, it also examines some of the discursive practices and methodological difficulties implicated in its marginalisation. However, in the context of “cultural pride strategies” associated with talk about an African Renaissance, indigenous healing may also function as a site of assertion of African power and resistance in its construction as an essentially African enterprise. At the same time, it may achieve disciplinary effects consonant with cultural pride strategies, in constructing afflictions in terms of neglect of, or disloyalty to cultural tradition. These results are discussed in terms of the methodological difficulties associated with interviewing and discourse analysis of translated texts, which contributes to difficulties with articulating indigenous healing discourse in a way that challenges the dominant psychiatric discourses implicated in its marginalisation within mental health. It concludes with recommendations for future research which addresses indigenous healing discourse in its own terms, and examines its operation as a disciplinary apparatus in South African society.

Full textAbstract:
Helichrysum longifolium and H. pedunculatum belong to the Astereceae family and are used extensively in folkloric medicine in South Africa to manage stress-related ailments and as dressings for wounds normally encountered in circumcision rites, bruises, cuts and sores. The in vitro antibacterial time-kill studies, the synergistic potentials, the phytochemical screenings and antioxidant potentials as well as the isolation of the bioactive compounds from the extracts of these two plants were carried out in this study. The in vitro antibacterial activities and time kill regimes of crude extracts of H. pedunculatum was assessed. The extracts was active against both Gram positive and Gram negative bacteria tested at a concentration of 10 mg/ml. Minimum Inhibitory Concentration (MIC) values for all the susceptible bacteria ranged between 0.1 – 35 mg/ml. The average log reduction in viable cell count in time kill assay ranged between 0.17 Log10 to 6.37 Log10 cfu/ml after 6 h of interaction, and between 0.14 Log10 and 6.99 Log10 cfu/ml after 12 h interaction in 1 × MIC and 2 × MIC of the extract. The effect of the aqueous extract was only bacteriostatic on both reference and environmental strains and the clinical isolates were outrightly resistant to aqueous extract. This is worrisome and this could be one reason why, there is an incidence of high death rate resulting from circumcision wounds infection even after treating such wounds with H. pedunculatum leaf. In vitro antibacterial time kill studies of extracts of H. longifolium was assessed. All test bacteria were susceptible to the methanol extract, while none was susceptible to the aqueous extract. Two of the test bacteria were susceptible to the ethyl acetate extract, while ten and seven were susceptible to the acetone and chloroform extracts respectively at the test concentration of 5 mg/ml. The minimum inhibitory concentrations (MICs) ranged between 0.1 and 5.0 mg/ml, while minimum bactericidal concentrations (MBCs) ranged between 1.0 and >5 mg/ml for all the extracts. Average log reductions in viable cell counts for all the extracts ranged between 0.1 Log10 and 7.5 Log10 cfu/ml after 12 h interaction at 1 × MIC and 2 × MIC. Most of the extracts were rapidly bactericidal at 2 × MIC achieving a complete elimination of most of the test organisms within 12 h exposure time. The effect of combinations of the crude extracts of H. pedunculatum leaves and eight antibiotics was investigated by means of checkerboard and time-kill methods. In the checkerboard method, synergies of between 45.83-56.81 percent were observed and this is independent of Gram reaction, with combinations in the aqueous extract yielding largely antagonistic interactions (18.75 percent). The time kill assay also detected synergy that is independent of Gram reaction with a ≥ 3Log10 potentiation of the bactericidal activity of the test antibiotics. We conclude that the crude leaf extracts of H. pedunculatum could be potential source of broad spectrum antibiotics resistance modulating compounds. The interactions between crude extracts of H. longifolium in combination with six first-line antibiotics using both the time-kill and the checkerboard methods were carried out. The time-kill method revealed the highest bactericidal activity exemplified by a 6.7 Log10 reduction in cell density against Salmonella sp. when the extract and Penicillin G are combined at ½ × MIC. Synergistic response constituted about 65 percent, while indifference and antagonism constituted about 28.33 percent and 6.67 percent in the time kill assay, respectively. The checkerboard method also revealed that the extracts improved bactericidal effects of the antibiotics. About 61.67 percent of all the interactions were synergistic, while indifference interactions constituted about 26.67 percent and antagonistic interactions was observed in approximately 11.66 percent. The in vitro antioxidant property and phytochemical constituents of the aqueous crude leaf extracts of H. longifolium and H. pedunculatum was investigated. The scavenging activity on superoxide anions, DPPH, H2O2, NO and ABTS; and the reducing power were determined, as well as the flavonoid, proanthocyanidin and phenolic contents of the extracts. The extracts exhibited scavenging activity in all radicals tested due to the presence of relatively high total phenol and flavonoids contents in the extracts. Our findings suggest that H. longifolium and H. pedunculatum are endowed with antioxidant phytochemicals and could serve as a base for future drugs. Bioactivity-guided fractionation of the leaves of H. longifolium and H. pedunculatum yielded two known compounds. From the n-hexane fraction of H. longifolium a compound was isolated (Stigmasterol) and from the ethyl acetate fraction of H. pedunculatum another compound (β-sitosterol) was isolated. The compounds were isolated and identified using various techniques. The antimicrobial, anti-inflammatory, antioxidant, analgesic and anti-pyretic activities of these compounds have been reported in literatures. In general, the experiments and tests conducted in this study appear to have justified the folkloric medicinal uses of H. longifolium and H. pedunculatum for the treatment of stress related ailments and wound infections and make a substantial contribution to the knowledge base of the use of herbal medicine for the treatment of the microbial infections.

Full textAbstract:
Xhosa psychiatric nurses stand unique at the interface between Western mental health care and indigenous healing in South Africa. They stem from a cultural history that is embedded within traditional health care discourses and yet are trained and work within a Western psychiatric model. In embodying the intersection between these two paradigms, they are faced with the challenge of making sense of such an amalgamation. These nurses' views are thus valuable in reflecting this intersection and illustrating many of the central concerns that surround it. This study explicates the views of these nurses toward traditional healers and their potential role in mental health care in South Africa. In addition, it illuminates some of the cultural dynamics at work amongst these subjects as they struggle to make sense of their unique cultural position. Using a questionnaire-based methodology, the views of Xhosa psychiatric nurses in a psychiatric hospital in the Eastern Cape, toward traditional healers and their role in mental-health care, were examined. The findings reveal that the vast majority of these nurses believe in traditional cosmology, involve themselves in traditional ritual practices and regularly visit traditional healers as patients. In suggesting ways in which indigenous healing and Western mental health care can work together, 75% of the nurses were in favour of a general referral system between the hospital and traditional healers, most (77%) agreed that certain patients would be better off being treated by both the hospital and traditional healers than they would if they were only being treated by the hospital alone, and 85% of the subjects agreed that patients who are already seeing traditional healers should check if psychiatric medication might help them. These findings indicate that these nurses operate across two healing systems which are at this point not conceptually compatible. This results in deep cultural tension for the nurses. In being entangled in the dialectical tension created in this context, the nurses manage the incongruencies in three general ways: a) Most, in one form or another, incorporate beliefs from both systems into an integrative model, b) some assimilate their cultural belief system into the Western mental health paradigm, throwing off their beliefs in traditional healing, and c) others remain ambivalent in the dialectic between traditional and Western health care discourses. Although this may suggest that these nurses reside within a cultural milieu that is somewhat unhealthy, at another level, in managing and containing the incompatibility between the two systems, these nurses ensure a space for on-going and healthy critique of the underlying assumptions involved in this health care malaise.

Full textAbstract:
According to the United Nations High Commissioner for Refugees (UNHCR), by 2012 there were 15.4 million refugees and 28.8 million internally displaced persons (IDPs) forced to flee their homes due to war or violent conflict across the globe. Upon arrival in their host settings, forced migrants struggle with acute health and material needs, as well as issues related to identity, politics, power and place. The Karen ethnic minority of Burma (also known as Myanmar) has been involved in a prolonged civil conflict with the Burmese military government for nearly six decades. This fighting has resulted in massive internal displacement and refugee flight, and although a ceasefire was signed in 2012, continued violence has been reported. This study among the displaced Karen population along the Thai-Burma border examines the relationships between traditional – or indigenous – medicine, the population's health needs, and the broader social and political context. Research was conducted using an ethnographic case-study approach among 170 participants along the Thai-Burma border between 2003 and 2011. Research findings document the rapid evolution and formalisation of the Karen traditional medical system. Findings show how the evolutionary process was influenced by social needs, an existing base medical knowledge among traditional health practitioners, and a dynamic social and political environment. Evidence suggests that that Karen traditional medicine practitioners, under the leadership of the Karen National Union (KNU) Department of Health and Welfare, are serving neglected and culturally-specific health needs among border populations. Moreover, this research also provides evidence that Karen authorities are revitalising their traditional medicine, as part of a larger effort to strengthen their social infrastructure including the Karen self-determination movement. In particular, these Karen authorities are focused on building a sustainable health infrastructure that can serve Karen State in the long term. From the perspectives of both refugee health and development studies, the revival of Karen traditional medicine within a refugee and IDP setting represents an adaptive response by otherwise medically under-served populations. This case offers a model of healthcare self-sufficiency that breaks with the dependency relationships characteristic of most conventional refugee and IDP health services. And, through the mobilisation of tradition for contemporary needs, it offers a dimension of cultural continuity in a context where discontinuity and loss of culture are hallmarks of the forced migration experience.

Full textAbstract:
Traditional healing is one of the most trusted methods of healing in South Africa, especially in rural areas, where health-care infrastructure is inadequate. People have depended on this method of healing since time immemorial. That belief has been strengthened by the fact that this method keeps people in touch with their ancestors. Traditional healers are trusted and believed to be the link between people and their ancestors. The Dwesa community is amongst the areas that still have strong belief in traditional healing. Traditional healers have a variety of methods of healing that they use, these methods have been trusted for people of all age groups. These methods are ukugabha, ukufutha and ukucima. Traditional healers prescribe them for both major and minor illnesses. They are believed to play a role in cleansing people from inside and outside. These methods together with other methods that are used in traditional healing are being explored in this study. This exploration is based on the fact that this information will be integrated into the teaching of isiXhosa to Pharmacy students at Rhodes University. This is an initiative to create awareness amongst health-care practitioners about traditional healing methods, so that they can caution and advise their patients about medicine taking behaviours, also to make them approach the subject in a sensitive manner. An isiXhosa course has been taught to Pharmacy students, as a pilot in 2007 and as an elective in 2008 onwards. This course deals with cultural issues in a broad manner, the issue of traditional healing specifically, and these methods of healing are outlined in the course, such that students have an understanding first of what a traditional healer is and their role in providing health-care services.

Previous issue date: 2011-02-22Esta dissertação busca se aproximar das concepções Pankararu de cura e suas relações com a biomedicina. Embora os Pankararu sejam originários da região do submédio São Francisco, no Estado de Pernambuco, depois de um intenso processo de migração, muitos deles passaram a residir na Favela do Real Parque, em São Paulo. Este estudo se concentra nos Pankararu do Real Parque. Este trabalho descreve partes da cosmologia Pankararu e suas formas tradicionais de cura, na busca de compreender a integração dessas práticas com o atendimento biomédico do Município de São Paulo. Descrevo então como ocorre essa integração, assinalando os conflitos e os processos de “tradução” e ressignificação de seus elementos rituais para o contexto urbano. O crescente número de etnias que vivem na metrópole suscita indagações quanto à transformação e readaptação de seus discursos. Esta etnografia pretende explicitar como é realizado esse movimento e as formas de afirmação identitária e de conquistas políticas, principalmente, no campo da saúde.
This essay seeks to approach the Pankararu concepts of healing and their relations with Biomedicine. Although Pankararu originate from the region of São Francisco submid, in the State of Pernambuco, after an intense process of migration, many ofthem took up residence in the shantytown of Real Parque, in São Paulo city. This study focuses on the Pankararu of Real Parque. This paper describes parts of the Pankararu cosmology and their traditional ways ofhealing, seeking to understand the integration of these practices with biomedical care in São Paulo city. I describe,then, how this integration occurs, pointing out the conflictsand the processes of "translation" and their redefinition of ritual elements to the urban context. The growing number of ethnic groups living in the metropolis raises questions aboutthe transformation and upgrading of their speech es. This ethnography aims to explainhow this movement takes place and the forms of identity affirmation and political achievements, especially in the health field.

A qualitative, exploratory, and descriptive study was conducted in Durban. Unstructured interviews and focus group interviews were conducted with registered and trainee psychologists respectively. Data was analyzed using thematic content analysis. Based on the findings the following conclusions were drawn: In comparison to student psychologists, intern and registered psychologists held more positive views about indigenous healing, its recognition, its role, and its inclusion into the formal health care sector. Most participants reported that they would not refer to indigenous healers unless a client made an explicit request; registered psychologists were more confident about their ability to collaborate with indigenous healers; and most participants reported a need for more knowledge on indigenous healing. The implications of these findings are discussed.This study was undertaken to explore trainee and registered psychologists' perceptions of

A thesis submitted to the Faculty of Humanities, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements of the degree of Doctor of Philosophy.
2016This study was conducted in an indigenous community of Tendera in Chiweshe District of Mashonaland Central Province in Zimbabwe. It pursued the possibilities of integrating indigenous knowledge of plant healing (IKoPH) into classroom science at The Zimbabwe Junior Certificate (ZJC) level. The study has documented this knowledge and has suggested ways that it could be integrated into the ZJC science curricula. My own background and the challenges of integrating indigenous knowledge into school science curriculum reform in Zimbabwe and elsewhere motivated me to undertake this study. This research journey preceded my full knowledge that these reforms encompass many complexities arising from two different knowledge systems. The integration process of indigenous knowledge in Zimbabwean schools has been very slow because of these complexities, which include lack of curriculum frameworks to guide teachers on what to teach, where to teach this knowledge in the westernised syllabi, how to access this knowledge from the community and how to teach it. Hence, the study argued that science teachers are in dire need of these guidelines and training. If this problem is left unattended, curriculum reform in Zimbabwe will remain a pipe dream. The study was framed within a self-developed Culturally Aligning Classroom Science (CACS) framework. It used a qualitative approach to research specifically engaging the Indigenous African Interpretive (IAI) methodology. Qualitative data were generated with purposely sampled teachers, healers and learners as core participants and community Elders, Ministry officers/practitioners and researchers as key participants. It was generated through video/audio and/or diarised observations, conversations, personal experiences and objects (documents and artefacts). The “kitic” analysis of data generated three major themes that are: (1) the community of Tendera is rich in IKoPH and its members have disparate views of integration that are significant for integrative classroom science. This IKoPH, however, emerged to be a sensitive, secretive, diverse and complex body of knowledge which requires access through culturally appropriate strategies, which demand collaboration between the community and the school; (2) The ZJC science curriculum presents several opportunities for integration of IKoPH that shows that this integrated curriculum is possible in Zimbabwe; and (3) oral pedagogical frames grounded in the parallel pathway to integration are potentially supportive of effective integrative classroom science. The study offers two models that could help integrators to overcome the complexities inherent in this reform. Further research into different aspects of these models and teacher capacitation to adopt them is needed to develop an integrative classroom science discourse.

Herbal medicines remain integral part of indigenous health care system in Ghana. Most conventional health medicines are directly or indirectly derived from plants or herbs. Despite its significant role in modern medicine indigenous herbal practices has been on the low light for some time due to perceived antagonistic relationship that exists between practitioners of herbal medicine and their counterpart in the conventional system.
Using an indigenous knowledge discursive framework, the thesis examined the relevance of herbal medicine to the contemporary Ghanaian society. The thesis also examined the tension between the indigenous herbal practitioners and their orthodox counterparts. The thesis noted that for health care system in Ghana to be effective, there is a need for collaborate relations between these two practitioners. Also, it was noted that for health care system to be effective in Ghana, spirituality has to be central in the works of the herbal practitioners.

Full textAbstract:
This dissertation examines why healing among the Yoruba people remained a successful popular institution in the colonial period between 1922 and 1955. The factors
that allowed the Yoruba healing system to flourish were diverse. The Yoruba’s indigenous and colonial political structures provided some outlets for continued healing practices. Additionally, the purely physical perspectives of western medical and religious competitors were unappealing to many Yoruba. Importantly, the Yoruba healers’
systematic and in-depth knowledge of medicinal remedies was attractive to patrons. Furthermore, Yoruba healers’ use of religious tools and/or the expansive use of spirituality reinforced this healing system as holistic, thus keeping the appeal of the system broad. Lastly, healers’ alliances, standards, certifications and publicity thereof bestowed greater credibility upon the system and its practitioners in an increasingly impersonal region.
While changes within Yoruba healing are revealed in this study, additional objectives of this work are to: illustrate the first known history of this institution; situate Yoruba healing as a legitimate system; include female healers in this investigation of Yoruba healing; and present a normal view of an ‘alternative’ medicine. The period of 1922 to 1955 is ideal to explore because various aspects that allowed the Yoruba healing
system to thrive developed during this time.text

This study explored into the effects of traditional medicine on reproductive health of rural women. Negative reports associated with traditional medicine due to bogus traditional practitioners expose most women to the harmful consequences of concoctions supplied and administered on them. However, factors such as people’s great confidence in traditional medicine and high costs associated with conventional Western medical treatments lead most rural women to traditional medicine usage. The study examined women’s perspectives on traditional medicine, factors which led rural women to use traditional medicine, meanings that people make about women and reproductive health, reproductive health implications of using traditional medicine as well as remedies for ensuring that traditional medicine is safe for women’s reproductive health. The study was grounded on the critical and socio-cultural theory. An explorative qualitative research was used. Data was collected through open-ended questions, observation as well as focus group interviews and then analysed using the thematic analysis method. The study participants consisted of rural women, traditional healers, elderly people and Western-trained doctors who were all sampled using non-probability sampling methods. The findings of the study showed that African traditional medicine plays a pivotal role in reproductive health care by offering readily available, cheap, culturally-oriented and accessible health care for most rural women. However, it was noted that the use of African traditional medicine by unqualified practitioners and the incorrect usage of the medicine by patients resulted in negative results that could lead to death or barrenness. Thus, the study recommends an introduction of a regulatory framework on the production, storage, use and trade of African traditional medicine.

traditional birth attendants (TBAs) from delivering mothers and ordered all mothers to
access skilled birth attendants in health facilities (MoH, 2007b). Anecdotal reports
showed that the influx of pregnant mothers to the health facilities resulted in mothers
delivering on make shift beds on the floor and sometimes without the assistance of the
skilled provider. The badly stretched health care system continues to force mothers to
deliver with the assistance of TBAs who have gone underground for fear of being fined.
Purpose of the study: The purpose of this study was to explore stakeholders’
perceptions of the changing role of TBAs in order to obtain a greater breadth of
understanding of the reasons why home births persist in the rural areas of Central West
Zone (CWZ), Malawi.
Methods: The study employed a mixed method concurrent triangulation design in which
24 health facilities in the districts of Ntcheu, Dedza, Lilongwe and Mchinji, in CWZ,
Malawi were included. A non-probability purposive sampling method was used to select
24 health facilities that provide Basic Emergency Obstetric and Neonatal Care
(BEmONC) services in rural areas of CWZ. A randomly selected sample was used to
collect quantitative data from mothers, using an interview schedule. These were
mothers (n=144) who had come to access maternal and neonatal health care but had
previously sought the help of a TBA to deliver. A total of 55 nurse midwives who
worked in the 24 health facilities and who were available and willing to participate
responded to a structured interview schedule. Quantitative data were analyzed using
SPSS version 19. Qualitative data were collected using focus group discussions (FGDs)
with TBAs (n=4 FGDs, with 6-7 respondents in each discussion group) who lived in the
catchment areas of the selected BEmONC sites. Single in- depth interviews were
conducted with TBA trainers (n=10) in the districts and health professionals (n=12) from
the Ministry of Health and Nurses and Midwives Council of Malawi. Data were analyzed
manually.
Findings: The findings showed that the moratorium on TBAs was implemented without
consultation with the relevant stakeholders and as a result, many mothers in rural areas
continued to seek the services of TBAs. Untrained TBAs took advantage of the
opportunity and together with some trained TBAs who were afraid of punishment went
underground to practice. Maternal and neonatal health care in BEmONC facilities were
deficient as the health care system struggled with challenges such as the lack of
adequate and humane accommodation for waiting mothers, critical shortages of staff,
drugs and supplies and negative health care worker attitudes. In addition, long
distances and the lack of empowerment of rural women prevented mothers from
seeking skilled birth attendants. The study concluded that even though the government
had issued a moratorium on TBAs, the health care system is not coping.
Recommendations: It is recommended that having moved away from the TBAs, there
is no need to revert to using them since that would mean perpetuating harmful and
substandard care for mothers. In addition, TBA services would undermine the
government’s efforts to improve skilled birth attendance. However, the system needs to
urgently deal with the challenges that rural mothers encounter in trying to access skilled
birth attendance.

Full textAbstract:
South Africa is currently revitalising the role of Traditional Health Practitioners (THPs) in
the country's healthcare provision. This undertaking is guided by Chinese Traditional
Medicine which is said to be one of the most highly developed traditional healthcare systems
in the world.
Programmes developed by the National Department of Health and other stake holders in the
development of indigenous medicine often need to be accommodated architecturally.
Collaboration with biomedicine is one of the main programmes aimed at empowering
Traditional Health Practitioners of the country.
Accordingly, this dissertation is divided into two sections, both based on the current
undertakings of collaboration between biomedicine and indigenous medicine in South Africa.
Due to the fact that traditional healing systems are less commonly described than
biomedicine, the main focus of this study is indigenous medicine and how architecture could
be influenced by alternative healthcare practices.
The first section (A) is theoretical. It investigates and compares the current architecture that
accommodates THPs in rural and urban areas of KwaZulu-Natal. This unveils social, cultural,
economic and political factors affecting this architectural genre. The aim thereof is to
establish architectural elements to be considered when designing a health care facility for
THPs. Section A also explores the current state of healthcare architecture in the country and
abroad so as to establish the latest challenges to be addressed by the proposed collaborative
healthcare model.
Design principles for collaborative architecture accommodating THPs and biomedical
practitioners in an urban context of South Africa are then be put forward.
Section B incorporates the theories derived from section A, towards the design of a joint
indigenous and biomedical healthcare centre for Durban. It gives specific spatial
requirements for a collaboration between biomedical practitioners and izinyanga.Thesis (M.Arch.)-University of KwaZulu-Natal, Durban, 2008.

This study investigated the preventive and promotive health care in the practice of indigenous healers. It focussed on specific aspects of primary health care. The objectives of the study were to describe the current practice of indigenous healers with regard to preventive and promotive health care. The study also identified specific areas in which indigenous healers practices with regard to preventive and promotive health care can be enhanced. It also intended to describe the effect of a short training course for indigenous healers based on the assessment, with regard to their knowledge, beliefs and practice. The study was a qualitative multi-phased research project which ircluded three phases. The researcher's target population ccnsisted of indigenous healers in Region D of KwaZulu-Natal. The researcher targeted indigenous healers living at Vryheid District Under Hlahlindlela tribal Authority. Sisters at the clinics in Vryheid and Pietermaritzburg participated in the present study as well as western medical practitioners and nurses at Edendale hospital. Focus group discussions and individual interviews were conducted. A template method of data analysis was used. Results revealed that indigenous healers practices were claracterized by preventive and promotive health measures which were, to a greater extent African -culture related. Areas of concern where indigenous healers practices would be enhanced were intensified by the formal health care workers. A short training course was designed and implemented by the researcher. Evaluation of the training course revealed that it was to a greater extent effective.Thesis (M.N.)-University of Natal, Durban, 2003.

Full textAbstract:
Thesis (M.CUR.) --University of Limpopo, 2014Indigenous practices (IPs) are experiences generated by people who are living in a specific region context and a specific cultured group. IPs are shaped by cultural traits that are passed from one generation to the next. The practices are rooted and embedded in such a society and, therefore, the practices become part of the people’s lifestyle. It is difficult to try and change these practices, since people have adhered to them throughout their entire lives. The believe system plays a major role in health care seeking behaviour of individuals because they are informed by the IPs that are observed in their environment (Shaik & Hatcher, 2005). IPs are stored in people’s memories and are expressed in songs, dances, beliefs, rituals, cultural values, myths, and healing of diseases by using herbs. During pregnancy, IPs are still applied worldwide. Ayaz and Efe (2008) indicate that it occurs mostly in Turkey and Africa where women’s reassurance is depending on the local context and meaning of pregnancy. THE PURPOSE OF THE STUDY To determine indigenous practices of pregnant women at the Dilokong Hospital in the Greater Tubatse Municipality of the Limpopo Province.This was achieved by the exploring and describing the indigenous practices of pregnant women in the antenatal (ANC) clinic of the maternity ward at the Dilokong Hospital.. DESIGN AND METHOD A qualitative, descriptive, explorative and contextual research design was used for the participants to describe the indigenous practices by pregnant women. Data was collected by means of unstructured one-on-one interviews in maternity unit of the ANC clinic at the Dilokong Hospital of the Greater Tubatse Municipality. Ethical considerations as described by Denosa (2000) were adhered to in order to ensure the v quality of the study. The criteria for trustworthiness were observed as stipulated in Babbie and Mouton (2009).Fifteen pregnant women were interviewed. FINDINGS AND RECOMMENDATIONS Four themes with sub-themes emerged from the data analysis by using Tech’ṡ open coding approach (Creswell 2006, Botma, Greef, Mulaudzi & Wright, 2010). Four themes were emerged namely; indigenous practices based on ancestral knowledge; indigenous practices based on spiritual diviners versus church principles; restricted practices versus instructions followed during pregnancy and labour and indigenous practices during labour and delivery. It is recommended that a national IP strategy needs to be developed to provide a framework and platform to support and promote grass roots IPs into mainstream development in the health care system in relation to midwifery practice. CONCLUSION The study findings indicated that IPs were regarded as an honourable health intervention by THPs, families, and pregnant women. They showed trust in methods used to preserve pregnancy, labour, and delivery, although, the indigenous practices by pregnant women still continue. Indigenous practices such as cords around their waists, are still observed during physical examinations. However, there is a reduction of prescribed potions mixed with cool drinks for use to accelerate labour and to prevent negative consequences because the potential toxicity has been explained during the provision of health education. These findings call for health care professionals to emphasise training and workshops for the THPs church diviners that are the fundamental principle of effective implementation of IPs to enhance improvement in the prevention of complications during pregnancy, labour and delivery.

Traditional medicines prepared from Sutherlandia frutescens are used to manage diseases including HIV and cancer. This study aimed at isolating and identifying biologically active compounds isolated from S. frutescens.
Sutherlandia frutescens plants were collected in Petrusburg and Paarl. Powdered plant material was extracted using ethanol or water and their metabolite composition was compared using UPLC-MS. A novel cycloartane, an acetylated variant of this compound as well as a Sutherlandioside B triterpenoid was isolated and characterised using chromatographic and analytical techniques such as NMR and UPLC-MS.
Preliminary biological studies were conducted to assess the activity of plant extracts on cell toxicity, herpes virus replication and cytokine expression. The results of this study suggest that aqueous extracts from S. frutescens do not appear to be cytotoxic or show anti-herpetic activity, but may activate the immune system by increasing expression of IL-6, IL-10 and TNFα. Further research should be conducted to confirm and optimise these results.Life and Consumer Sciences

Full textAbstract:
Ingestion of extracts prepared from various medicinal plants to induce or augment labour
is common amongst Black South African women during the late stages of pregnancy.
This applies particularly to the rural areas where modern health care facilities are often
lacking. Many of these plants have not been investigated scientifically and one needs to
substantiate claims of quality, safety and efficacy. Furthermore, it is believed that the
consumption of these plant extracts can result in foetal meconium staining at delivery.
An investigation into the uterotonic properties of three plants viz. Ekebergia capensis
Sparrm. Clivia miniata (Lindl.) Regel. and Grewia occidentalis L. were carried out using
guinea pig uterine smooth muscle in vitro. Supercritical fluid extraction was performed
with water modified supercritical carbon dioxide to extract the uterotonic components.
An attempt was also made to couple supercritical fluid extraction directly on-line to the
bioassay so that on line screening of crude plant extracts could be performed within short
periods of time. The effects of supercritical CO2 decompression on temperature and pH of
the muscle bathing solution were considered since these factors affect muscle
contractility. The direct effects of excess CO2 on intracellular mechanisms were
eliminated by constructing a CO2 reduction interface together with passage of carbogen
which aided in the rapid displacement of excess CO2, As samples of these extracts were
found to induce muscle contraction, supercritical fluid fractionation (SFF) was performed
by sequentially increasing the fluid density. Extracted fractions were obtained by
sequentially increasing the pressure at constant temperature and modifier concentration in
an attempt to identify the active fractions. Extractions were performed at 200 atm, 300
atm and 400 atm respectively. Subsequent testing of these fractions enabled the detection
of active and inactive fractions as well as a fraction that had a spasmolytic effect on
uterine muscle. The 400 atm extracts of E. capensis and C. miniata displayed maximum
activity while only the 300 atm extract of G. occidentalis induced uterine muscle
contraction. Subsequent analysis of the sequentially extracted fractions, by high
performance liquid chromatography and micellar electrokinetic capillary chromatography
revealed that certain compounds present in the fractions that stimulated muscle
contraction, were sensitive to the extraction pressure hence making it possible to
determine the compounds that were likely to be active. Column chromatography
followed by various spectroscopic techniques were performed in an attempt to isolate and
elucidate the structures of the compounds that were present in the plant extracts. The
extract of Ekebergia capensis yielded five known compounds (B-sitosterol, oleanonic
acid, 3-epioleanolic acid, 2,3,22,23-tetrahydroxy-2,6,1 0, 15,19 ,23-hexamethyl-6, 10, 14, 18-
tetracosatetrene and 7-hydroxy-6-methoxy coumarin. The extract of Clivia miniata
yieded linoleic acid and 5-hydroxymethyl-2-furancarboxaldehyde while the extract of
Grewia occidentalis yielded 3-(4-hydroxy-3-methoxyphenyl)-2-propenal, a novel
compound 2,2' ,6,6'-tetramethoxy-4'-al-4-(w-oxo-E-propenyl)-biphenyl and oleanonic
acid. The pure compounds were further evaluated pharmacologically to identify the
active components and assess the physiological mode of action by the use of various
receptor blockers. Oleanonic acid, 3-epioleanolic acid, linoleic acid and 5-
hydroxymethyl-2-furancarboxaldehyde and 3-(4-hydroxy-3-methoxyphenyl)-2-propenal
were found to induce an agonistic muscle response. All these compounds were observed
to mediate their effects through the cholinergic receptors. The results obtained in this
study supports the claim of these plants possessing uterotonic properties.Thesis (Ph.D.)-University of Natal, Durban, 1997.

Full textAbstract:
This thesis explores the attempts by international law to recognize and protect the knowledge of indigenous and local communities. In conducting this inquiry, the thesis focuses on traditional medicine and the central role played by plant biodiversity in this aspect of local knowledge. It observes that the ongoing debate over the protection of indigenous knowledge is dominated by the question of suitability or otherwise of mainstream intellectual property rights to indigenous knowledge. It argues that despite major efforts to reconcile the Western concept of intellectual property rights with indigenous knowledge forms, such attempts have undermined the epistemic schism at the root of indigenous and non-indigenous knowledge systems. Intellectual property rights, particularly the patent regime, are designed to legitimize or validate a Western scientific approach to phenomena. Indeed, the patent process does not recognize the socio-cultural character of science. Seeking to protect indigenous knowledge by means of mainstream intellectual property rights, even in their suggested sui generis forms without accommodating the idea of epistemic pluralism may be counterproductive to the goal of protecting indigenous knowledge. In the context of traditional medicine, intellectual property privileges Western biomedicine because of the former's appeal to a narrow view of science. Consequently, the psychosocial foundation ; of traditional therapeutic culture is not accounted for by mainstream intellectual property. In traditional medicine, the therapeutic and the pharmaceutical are fused within an indigenous holistic worldview. However, Western biomedicine does not recognize such a fusion. Rather its fragmentary or organismic approach both in theory and practice is one that readily fits within the mould recognized by the dominant concept of intellectual property. To protect indigenous knowledge, particularly traditional medicine and consequently advance the movement toward medical pluralism, this thesis makes a case for a cross-cultural approach to intellectual property rights. Modalities for the protection of knowledge that recognize the importance of cultural integrity and the contexts in which knowledge systems are generated have become an imperative. Perhaps the most appealing starting point for this approach is the prevailing customary norms and knowledge protection protocols within indigenous communities. Knowledge protective mechanisms do not necessarily have to imitate mainstream intellectual property rights. A cross-cultural approach to the protection of knowledge, unlike the mainstream intellectual property rights framework, is an inclusive and not an exclusive enterprise. Such an approach endorses the notion that intellectual property could advance a balanced as opposed to a narrow cultural vision. The cross-cultural approach advanced in this thesis is a framework concept to be championed primarily by national governments at the base community levels. It is proposed as a viable direction for the ongoing international efforts aimed at developing an appropriate protective mechanism for indigenous knowledge, a mechanism that does not compromise indigenous cultural integrity and the inherent benefits of epistemic pluralism.

PhD (African Studies)Department of African Studies
Traditional health practice is an important and often underestimated part of health care. Since time immemorial traditional health ensured and covered all major areas of health promotion, which included preventative, promotive, curative, rehabilitative, and surgical practices. In low- and middle-income countries where the number of practitioners of modern medicine may not be enough to meet the health care needs of the country, traditional health promotion is central. Given that in many societies the practices are done in secret, it therefore makes it difficult for people in general to access proper service from traditional health practitioners. This study explored the role of traditional health practitioners in promoting health in a rural community. The study adopted a qualitative approach which was descriptive, explorative and interpretative, targeting the registered traditional health practitioners in villages of Ward X of the Pfura Rural District Council. A non-probability purposive and snowball sampling method was used to identify twenty-two (22) male and female participants. The participants were registered diviners, herbalists and traditional birth attendants. The data which was collected through in-depth interviews, field notes, audio recordings and observation were thematically analyzed using Tesch’s method of data analysis and presented in categories, themes and subthemes. The study revealed that the traditional health practitioners in Pfura, are playing a vital role in offering primary health care for the people. Traditional health practitioners offer healing through their extensive knowledge of herbal and animal-based medicines and therapeutic actions such as rituals. The study established the use of herbs, traditional ceremonies, taboos, cultural norms as health promotive practices. Traditional healers in Pfura have demonstrated their efficacy and remained a powerful establishment in society through their easy access to the ancestral spirits, which has sustained the healing culture of Kore-kore people. Despite the central role being played by traditional health system in health promotion, impediments were found against the practice and its practitioners. Poor professional development, research and training of the Traditional Health Practitioners as well as the advanced age of practitioners is a setback in the practice as it contributed negatively to the sustainability of the traditional health practice. Guided by both study findings, key action areas of health promotion of the Ottawa Charter and the objectives of the World Health Organization, Traditional Medicine Strategy of 2014-2023 target, a framework/guide was developed and recommended an integrative and sustainable health promotion in a rural setting.

Thesis (M. Agricultural Management (Animal Production)) -- University of Limpopo, 2018Ethno veterinary medicine practices are popular among the resource constrained small-holder farmers. Nonetheless, the effectiveness of traditional remedies particularly the indigenous plants has not been extensively documented. Hence, this study was conducted to determine efficacy of indigenous plant extracts used by small-holder farmers in Chief Albert Luthuli Local Municipality, Mpumalanga Province, South Africa for internal parasites control. Information on indigenous plants used for the control of internal parasites of livestock by local farmers in the study area was gathered through a questionnaire survey. A total of 188 livestock farmers (both males and females) of mixed ages were interviewed. Thirteen different plants were frequently mentioned by the respondents as remedies for livestock internal parasites. Of these, seven plants could be identified up to their families and species. Plant species collected were Dicerocaryum sp (50%), Pappeacapensis (61%), Aloe ferox (90%), Helichrysum sp (56%), Senecio congestus (83%), Senecio barbertonicus (67%) and Gardenia sp (73%). These plants were extracted using distilled water and analysed to determine their efficacy through in vitro assays; Egg hatch, larval development and larval mortality assays. All the assays were performed at different concentrations of 2.5mg/ml, 5.0mg/ml and 7.5mg/ml. The nematode third stage larvae were incubated for 24hr, 48hr and 72hr during the larval mortality assay. The present study showed that all the seven-plant species under investigation possessed some anthelmintic activities of varying strength. The highest egg hatch inhibition was observed from the extracts of Senecio barbertonicus with 100 % and the lowest from Dicerocaryum eriocarpum with 2.25 %, for larval development the highest was Gardenia sp 100 % and the lowest Helichrysum sp 26 % at concentration 7.5 mg/mL respectively. Whereas, the highest in larval mortality assay was Senecio barbertonicus and Gardenia sp achieved 100 % after 48hrs and the lowest was Dicerocaryum eriocarpum with49.89 % after 72hrs at concentration 7.5 mg/mL respectively. The use of other different forms of extraction media is recommended because different results can observe and be compared with the results of the present study. Toxicity studies on the indigenous plants observed to have stronger anthelmintic activities would assist in the future recommendation of these remedies for large scale or commercial use as anthelmintic drugs.

Full textAbstract:
Abstract in EnglishThe number of studies focused on the digital preservation of indigenous knowledge has been growing steadily over the years. Despite the growth in this area of research, there is still a lack of information technology tools that preserve and disseminate indigenous knowledge. Indigenous knowledge has been highlighted as an area that can advance sustainable development, and its preservation is therefore of the utmost importance. Indigenous knowledge is mostly present within older generations, and if it is not preserved, this knowledge will die with its custodians. African communities rely heavily on indigenous medicine. A digital platform needs to be explored that can preserve practices relating to these medicines for future generations. Since indigenous knowledge is dynamic and is constantly evolving, there is a need to explore a digital tool that can highlight this dynamic nature. Current methods of preserving indigenous knowledge of medicinal plants were found to be less than effective and marred by constraints such as space and time. The main objective of this study was therefore to develop a model that could be used to guide the design of a new e-learning system aimed at facilitating the preservation of indigenous knowledge of Namibia’s medicinal plants. In this study, e-learning technology was used to determine the requirements for presenting indigenous knowledge of Namibia’s medicinal plants in such a way as to ensure that individuals can internalise and preserve this knowledge. An interpretivist qualitative approach was followed. Data was collected by conducting a literature review and carrying out a survey. A prototype e-learning system was developed and evaluated based on the collected data. It was found that preserving indigenous knowledge of medicinal plants through e-learning would require, among other things, engagement with the relevant knowledge custodians, leveraging multimedia, and offering content in indigenous languages.
