The role of traditional healers in the diagnosis and management of Burkitt lymphoma in Cameroon: understanding the challenges and moving forward.

BACKGROUND: Burkittlymphoma(BL) is the most common childhood cancer in Cameroon with a reported incidence of 3 per 100,000 children under 15 years in the Northwest region. Treatment at three Baptist mission hospitals has a recorded cure rate of over 50%. Traditional medicine(TM) is recognized by the national health system, but its scope is undefined and entraps children with BL. The aim of this study was to investigate the attitudes and practices of parents and traditional healers (TH) towards TM in children with BL in order to develop recommendations for an integrative approach and improved access to life-saving treatment for children with BL. METHODS: This is a descriptive case series of children diagnosed with BL treated at Banso, Mbingo, and Mutengene Baptist Hospitals between 2003 and 2014. A questionnaire was used to obtain the following information: demographic information, religion, the rate of use of TM, reasons why guardians chose to use TM, the diagnoses made by the TH, treatment offered, and the type of payment requested, based on the accounts of patient caregivers. Data was analyzed using Center for Disease Control Epi Info 7. RESULTS: Three hundred eighty-seven questionnaires were completed by parents/guardians. 55% had consulted a TH, of whom 76.1% consulted the TH as first choice. Common diagnoses provided by TH included liver problem, abscess, witchcraft, poison, hernia, side pain, mushroom in the belly and toothache. Methods of management included massage, cuts, concoctions, and incantations. The fee for these services included chickens, farm tools, and cash ranging from 200FCFA (0.4USD) to 100,000FCFA(200USD). The choice of TM was based on accessibility, failed clinic/hospital attendance, recommendation of relatives, and belief in TM. CONCLUSIONS: TH are involved in BL management in Cameroon. TH are ignorant about BL, resulting in non-referral, and thus delay in diagnosis and treatment. Collaboration with TH could reduce late diagnosis and improve cure rates of BL and other childhood cancers.

The potential of selected South African plants with anti-Klebsiella activity for the treatment and prevention of ankylosing spondylitis.

A wide variety of herbal remedies are used in traditional African medicine to treat inflammatory disorders, including some autoimmune diseases. Thirty-four extracts from 13 South African plant species traditionally used for the treatment of inflammation were investigated for their ability to control a microbial trigger for ankylosing spondylitis (Klebsiella pneumoniae). Twenty-six of the extracts (76.5%) inhibited the growth of K. pneumoniae. Methanol and water extracts of Ballota africana, Carpobrotus edulis leaves, Kigellia africana, Lippia javanica, Pelargonium fasiculata, Syzygium cordatum (including bark), Terminalia pruinoides and Terminalia sericea were effective K. pneumoniae inhibitors, with MIC values <1000 µg/ml. The roots of Tulbaghia violaceae and bark from Warburgia salutaris also demonstrated efficacy. The most potent extracts were examined by RP-HPLC and UV-Vis spectroscopy for the presence of resveratrol. Methanolic extracts of B. africana, C. edulis leaves, L. javanica, T. pruinoides and T. sericea, as well as aqueous B. africana, T. pruinoides and T. sericea extracts, displayed peaks with retention times and UV-Vis spectra consistent with the presence of resveratrol. Resveratrol was generally a minor component, indicating that resveratrol was not solely responsible for the anti-Klebsiella growth inhibitory properties. Plant extracts with K. pneumoniae inhibitory activity were either non-toxic, or of low toxicity in the Artemia (brine shrimp) nauplii bioassay. Their low toxicity and antibiotic bioactivity against K. pneumoniae indicate their potential for both preventing the onset of ankylosing spondylitis and minimising its symptoms once the disease is established.

The use of South African botanical species for the control of blood sugar.

ETHNOPHARMACOLOGICAL RELEVANCE: Diabetes mellitus (DM) is one of the most prevalent diseases globally and is of considerable concern to global health. Approximately 425 million people are estimated to have DM globally and this is predicted to increase to >642 million by 2040. Whilst the prevalence of DM in South Africa is slightly lower than the global average, it is expected to rise rapidly in future years as more South Africans adopt a high calorie "westernised" diet. Traditional medicines offer an alternative for the development of new medicines to treat DM and the usage of South African plants is relatively well documented. AIM OF THE STUDY: To critically review the literature on the anti-diabetic properties of South African plants and to document plant species used for the treatment of DM. Thereafter, a thorough examination of the related research will highlight where research is lacking in the field. MATERIALS AND METHODS: A review of published ethnobotanical books, reviews and primary scientific studies was undertaken to identify plants used to treat DM in traditional South African healing systems and to identify gaps in the published research. The study was non-biased, without taxonomic preference and included both native and introduced species. To be included, species must be recorded in the pharmacopeia of at least one South African ethnic group for the treatment of DM. RESULTS: One hundred and thirty-seven species are recorded as therapies for DM, with leaves and roots most commonly used. The activity of only 43 of these species have been verified by rigorous testing, and relatively few studies have examined the mechanism of action. CONCLUSION: Despite relatively extensive ethnobotanical records and a diverse flora, the anti-diabetic properties of South African medicinal plants is relatively poorly explored. The efficacy of most plants used traditionally to treat DM are yet to be verified and few mechanistic studies are available. Further research is required in this field.

Medicinal plants used to treat "African" diseases by the local communities of Bwambara sub-county in Rukungiri District, Western Uganda.

ETHNOPHARMACOLOGICAL RELEVANCE: In Africa, traditional medicine encompasses a diverse range of practices, including herbalism and spiritualism, where some diseases are believed to be "African" since they can only be traditionally treated. Indigenous knowledge on the management of "African" diseases using medicinal plants is still handed down orally from generation to generation by tribal societies of tropical Africa, and with the rapid westernization of these societies there is a pressing need to record local knowledge before it is lost forever. AIM: This study documented medicinal plant species associated with the management of "African" diseases by the local communities of Bwambara sub-county in Rukungiri district, Western Uganda. METHODS: A cross-sectional study was conducted using semi-structured questionnaires and interviews. The data collected included names of plant species, plant parts used, diseases treated, methods of preparation, and mode of administration of the herbal remedies. A total of 196 informants participated in the study. Data were analyzed and presented using descriptive statistics and the Informant consensus factor. RESULTS: We documented 67 medicinal plant species distributed over 27 families and 62 genera. The most commonly reported species belong to Asteraceae family. The most frequently used medicinal species were Chenopodium opulifolium (27), Sesbania sesban (26), Thevetia peruviana (25), Leonotis nepetifolia (23), Momordica foetida (23), Euphorbia hirta (21) and Cassia mimosoides (20). Leaves were the most commonly used plants parts and decoctions were the main method of preparation. Water was the main medium used for the preparation of the remedies which were administered orally while petroleum jelly was the main medium for those which were used as ointments. The medicinal plant species reported are used to treat 39 conditions which were clustered into 10 International Classification of Primary Care (ICPC) disease categories. There is a high degree of consensus among the informants on which medicinal plant species they use for different diseases especially disorders in the following categories: neurological (FIC = 0.90), general and unspecified (FIC = 0.87), digestive (FIC = 0.86) and female genital (FIC = 0.82). CONCLUSION: Local communities of Bwambara sub-county in Rukungiri district, Western Uganda use a rich diversity of medicinal plant species in the management of various "African" diseases. Therefore, collaboration between users of medicinal plants and scientists is paramount, to help in the discovery of new drugs based on indigenous knowledge.

The traditional use of southern African medicinal plants in the treatment of viral respiratory diseases: A review of the ethnobotany and scientific evaluations.

ETHNOPHARMACOLOGICAL RELEVANCE: Viral respiratory infections are amongst the most common infections globally, with most of the world's population contracting at least one infection annually. Numerous plant species are used in traditional southern African healing systems to treat these diseases and to alleviate the symptoms. Despite this, the therapeutic potential of these plants against viral respiratory diseases remains poorly explored. AIM OF THE STUDY: The aim of this study was to document the southern African plant species used in traditional medicine to treat viral respiratory infections. We also examined the extent of scientific evaluations of southern African plant species against the respiratory-infective viruses, with the aim of stimulating interest in this area and focusing on future studies. MATERIALS AND METHODS: We undertook an extensive review of ethnobotanical books, reviews and primary scientific studies to identify southern African plants which are used in traditional southern African medicine to treat viral respiratory diseases. This information was used to identify gaps in the current research that require further study. RESULTS: Two hundred and fifty-seven southern African plant species were identified as traditional therapies for viral respiratory diseases. Surprisingly, only one of those species (as well as twenty-one other species not recorded for these purposes) has been evaluated for the ability to block respiratory virus production. Furthermore, most of these studies screened against a single viral strain and none of those studies examined the mechanism of action of the plant preparations. CONCLUSIONS: Despite well documented records of the use of southern African plants to treat respiratory viral diseases, the field is poorly explored. Nearly all of the plant species used in traditional healing systems to treat these diseases are yet to be tested. Substantial further work is required to verify the efficacy of these traditional medicines.

The traditional use of southern African medicinal plants for the treatment of bacterial respiratory diseases: A review of the ethnobotany and scientific evaluations.

ETHNOPHARMACOLOGICAL RELEVANCE: Multiple plant species were used traditionally in southern Africa to treat bacterial respiratory diseases. This review summarises this usage and highlights plant species that are yet to be verified for these activities. AIM OF THE STUDY: This manuscript reviews the traditional usage of southern African plant species to treat bacterial respiratory diseases with the aim of highlighting gaps in the literature and focusing future studies. MATERIALS AND METHODS: An extensive review of ethnobotanical books, reviews and primary scientific studies was undertaken to identify southern African plants which are used in traditional southern African medicine to treat bacterial respiratory diseases. We also searched for southern African plants whose inhibitory activity against bacterial respiratory pathogens has been conmfirmed, to highlight gaps in the literature and focus future studies. RESULTS: One hundred and eighty-seven southern African plant species are recorded as traditional therapies for bacterial respiratory infections. Scientific evaluations of 178 plant species were recorded, although only 42 of these were selected for screening on the basis of their ethnobotanical uses. Therefore, the potential of 146 species used teraditionally to treat bacterial respiratory diseases are yet to be verified. CONCLUSIONS: The inhibitory properties of southern African medicinal plants against bacterial respiratory pathogens is relatively poorly explored and the antibacterial activity of most plant species remains to be verified.

Antimicrobial investigation of ethnobotanically selected guinean plant species.

ETHNOPHARMACOLOGICAL RELEVANCE: In Guinea, medicinal plants play an important role in the management of infectious diseases including urinary disorders, skin diseases and oral diseases. This study was carried out to collect medicinal plant species employed for the treatment of these diseases and to investigate their antimicrobial potential. MATERIALS AND METHODS: Based on an ethnobotanical investigation carried out in three Guinean regions, 74 traditional healers and 28 herbalists were interviewed and medicinal plants were collected. The most quoted plant species were evaluated for their antimicrobial activities against Staphylococcus aureus, Escherichia coli, Candida albicans, and in addition against Plasmodium falciparum. RESULTS: A total of 112 plant species belonging to 102 genera distributed over 42 botanical families were inventoried. Among the selected plant species, promising activities against C. albicans were obtained for the methanolic extracts of the stem bark of Terminalia albida (IC50 1.2 µg/ml), the leaves of Tetracera alnifolia (IC50 1.6 µg/ml) and the root bark of Swartzia madagascariensis (IC50 7.8 µg/ml). The highest activity against S. aureus was obtained for the dichloromethane extracts of the leaves of Pavetta crassipes (IC50 8.5 µg/ml) and the root of Swartzia madagascariensis (IC50 12.8 µg/ml). Twenty one extracts, obtained from twelve plant species, were strongly active against Plasmodium falciparum, including the dichloromethane extracts of the root and stem bark of Terminalia albida root (IC50 0.6 and 0.8 µg/ml), the leaves of Landolphia heudelotii (IC50 0.5 µg/ml), the stem bark of Combretum paniculatum (IC50 0.4 µg/ml) and the leaves of Gardenia ternifolia (IC50 1.3 µg/ml). CONCLUSION: The present study provides a comprehensive overview of medicinal plants employed by Guinean traditional healers for the treatment of various microbial diseases, including urinary disorders, skin diseases and oral diseases. Some of the studied plant species showed promising antimicrobial activity and could be considered as a potential source for the development of new antifungal and/or antimalarial agents.

A narrative analysis of the link between modern medicine and traditional medicine in Africa: a case of mental health in Uganda.

BACKGROUND: Traditional Medicine Practices (TMP) which are premised on indigenous knowledge and experiences within a local context of the culture and environment, are common place in low income countries. In Africa and in Uganda specifically, nearly 80% of the Ugandan population relies on TMP for the care of their mental health but they also use Modern Medicine. There are areas of departure between Traditional and Modern Medical practices in Africa that have been cited. What has attracted less research attention, are the areas of convergence. OBJECTIVE: This paper aims to critically examine the link between Modern Medicine and Traditional Healing Practices in Africa, citing Uganda as case example. METHOD: A Narrative literature review with critical element assessment was undertaken to identify documented points of departure, areas of common practice, and ways in which the two models can co-exist and work together through a carefully thought out integration. RESULTS: Points of departure between Modern Medicine and Traditional Medicine Practices are philosophical underpinnings of both practices, training of practitioners, and methods and ethics of work. Common areas of practice include human rights perspective, descriptions of mental illnesses, clinical diagnostic practice, particularly severer forms, intellectual property rights, and cross prescriptions. Exhibiting cultural humility and responsibility on the side of the Modern Medicine Practitioners is one of the ways to work together with TMPs. CONCLUSION: Points of departure are more documented and explicit and overshadow areas of common practice while the links between the two are mainly implicit but sadly unrecognized. Mental disorders are disorders of the brain and in neuroscience; the brain is culturally and socially constructed. Sociocultural issues therefore cannot be divorced from disorders of the brain and their management. For better patient outcome and patient-centered approach of care, it is necessary to acknowledge and enhance the links in teaching, clinical and policy level and carry out research on how the links could be improved.

TREATMENT OF DIARRHOEA USING TRADITIONAL MEDICINES: CONTEMPORARY RESEARCH IN SOUTH AFRICA AND ZIMBABWE.

BACKGROUND: Gastrointestinal disorders, diarrhoea in particular remain a major concern in South Africa and Zimbabwe resulting in high mortality rates when left untreated. This investigation was aimed at documenting herbal medicines used in the treatment of diarrhoea in South Africa and Zimbabwe. MATERIALS AND METHODS: A review of literature on plant species used as remedies for diarrhoea in South Africa and Zimbabwe was undertaken by the use of different electronic databases such as Google Scholar, ScienceDirect, Scopus as well as library searches at the University of Fort Hare, South Africa and the National Herbarium of Zimbabwe (SRGH) in Harare, Zimbabwe. RESULTS: This study reported ten plant species most widely used to treat diarrhoea in South Africa and Zimbabwe. Of the lot, Sclerocarya birrea (A. Rich.) Hochst. was the most popular medicinal plant used as antidiarrhoeal remedy (11 literature citations) in South Africa and Zimbabwe, followed by Elephantorrhiza elephantina (Burch.) Skeels and Schotia brachypetala Sond. with eight literature citations each. The roots (47.4%) are the most frequently used plant parts, followed by bark (26.3%), leaves (21.1%) and rhizomes (5.3%). CONCLUSION: The documented antidiarrhoeal activities of this repository of selected plant species against diarrhoea causing agents such as rotavirus, Escherichia coli, Shigella, Campylobacter, Giardia, Entamoeba histolytica, Salmonella, Yersinia and Vibrio cholerae calls for further investigation aimed at isolating phytochemical compounds responsible for antidiarrhoeal activities, their mode of action, and also establish their safety and efficacy. This cross-cultural acceptance of antidiarrhoeal herbal medicines and the use of the same plant species in different geographical zones serve as an indication of the importance of herbal medicines in primary healthcare of local communities.

Grandmothers as gatekeepers? The role of grandmothers in influencing health-seeking for mothers and newborns in rural northern Ghana.

Previous research suggests that care-seeking in rural northern Ghana is often governed by a woman's husband or compound head. This study was designed to explore the role grandmothers (typically a woman's mother-in-law) play in influencing maternal and newborn healthcare decisions. In-depth interviews were conducted with 35 mothers of newborns, 8 traditional birth attendants and local healers, 16 community leaders and 13 healthcare practitioners. An additional 18 focus groups were conducted with stakeholders such as household heads, compound leaders and grandmothers. In this region, grandmothers play many roles. They may act as primary support providers to pregnant mothers, care for newborns following delivery, preserve cultural traditions and serve as repositories of knowledge on local medicine. Grandmothers may also serve as gatekeepers for health-seeking behaviour, especially with regard to their daughters and daughters-in-law. This research also sheds light on the potential gap between health education campaigns that target mothers as autonomous decision-makers, and the reality of a more collectivist community structure in which mothers rarely make such decisions without the support of other community members.

Traditional medicine policy and regulation in Nigeria: an index of herbal medicine safety.

BACKGROUND: The requirements and methods for research and evaluation of the safety and efficacy of herbal medicines are more complex than those for conventional pharmaceuticals. In addition to the aforementioned and contrary to the general belief that herbal medicines are safe and despite the profound therapeutic advantages possessed by medicinal plants, some of their constituents have been shown to be potentially toxic, carcinogenic, mutagenic, and teratogenic. Thus, traditional medicine policy and regulation have been made an integral part of the WHO proposed critical determinants of herbal medicine safety. OBJECTIVE: Therefore, this study is designed to assess the policy and regulation guiding herbal medicine in Nigeria as this information may form a safety index of herbal medicine use in Nigeria. METHODOLOGY: Structured questionnaire adopted from WHO was used to obtain the opinions of relevant stakeholders in the field of herbal medicine on the policy and regulation of herbal medicine in Nigeria. RESULTS: The results show that 68.8% of respondents agreed that there is a national policy on TM with 31.2% disagreeing on this issue. 75% of respondents agreed that implementation of the manufacturing requirements of herbal medicines is ensured by control mechanisms while 25% disagreed. Only 25% said herbal medicines are sold by licensed practitioners, with 75% believing that herbal medicines are sold by non-licensed practitioners. 87.5% said support from the WHO is needed and should be in the form of workshops on national capacity building on safety monitoring of herbal medicines. CONCLUSION: There is need for the Federal Ministry of Health to harmonize the varying opinions on traditional medicine and policy as documented in this study through collaboration and workshops on traditional medicine. These proposed approaches may guarantee the safety and regulation of herbal medicine use in Nigeria.

Traditional healers formalised?

Traditional healers are the first to be called for help when illness strikes the majority of South Africans. Their communities have faith in their ability to cure or alleviate conditions managed by doctors, and much more. A visit to such practitioners' websites (they are up with the latest advertising technology!) shows that they promise help with providing more power, love, security or money, protection from evil people and spirits, enhancing one's sex life with penis enlargement and vagina tightening spells, etc. Contemplating such claims, it is easy to be dismissive of traditional healers. But in this issue of the SAMJ Nompumelelo Mbatha and colleagues1 argue that the traditional healers' regulatory council, promised by an Act of Parliament, should be established, followed by (or preferably preceded by) formal recognition by employers of sick certificates issued by traditional healers. Can matters be so simply resolved? What does this mean for doctors and other formally recognised healthcare professionals, and how to respond to such claims and social pressures?

Trends and challenges of traditional medicine in Africa.

Prior to the introduction of cosmopolitan medicine, traditional medicine used to be the dominant medical system available to millions of people in Africa in both rural and urban communities. However, the arrival of the Europeans marked a significant turning point in the history of this age-long tradition and culture. This paper examines the trends and challenges of traditional medicine in Africa. The impact of colonialism on African traditional medicine is also examined. Although the paper is on Africa, references are drawn around the world to buttress the growing demand for traditional medicine. The paper concludes that to minimise the current distrust between modern and traditional doctors and to achieve the objective of regulation, standardisation and cooperation, both traditional and modern doctors must acknowledge their areas of strengths and weaknesses from which they operate and be genuinely concerned about the difficult but necessary task of being human.

Traditional medicine: past, present and future research and development prospects and integration in the National Health System of Cameroon.

Traditional medicine refers to health practices, approaches, knowledge and beliefs incorporating plant, animal and mineral based medicines, spiritual therapies, manual techniques and exercises, applied singularly or in combination to treat, diagnose and prevent illnesses or maintain well-being. In the last decade traditional medicine has become very popular in Cameroon, partly due to the long unsustainable economic situation in the country. The high cost of drugs and increase in drug resistance to common diseases like malaria, bacteria infections and other sexually transmitted diseases has caused the therapeutic approach to alternative traditional medicine as an option for concerted search for new chemical entities (NCE). The World Health Organisation (WHO) in collaboration with the Cameroon Government has put in place a strategic platform for the practice and development of TM in Cameroon. This platform aims at harmonizing the traditional medicine practice in the country, create a synergy between TM and modern medicine and to institutionalize a more harmonized integrated TM practices by the year 2012 in Cameroon. An overview of the practice of TM past, present and future perspectives that underpins the role in sustainable poverty alleviation has been discussed. This study gives an insight into the strategic plan and road map set up by the Government of Cameroon for the organisational framework and research platform for the practice and development of TM, and the global partnership involving the management of TM in the country.

Traditional healers as caregivers to HIV/AIDS clients and other terminally challenged persons in Kanye community home-based care programme (CHBC), Botswana.

The research study done at the Kanye village of Botswana was qualitative in design and exploratory in nature. While the broad goal aimed at assessing the contributions of caregivers in the Kanye CHBC programme, this article aims at evaluating the traditional Healers' contribution as providers of care to HIV/AIDS patients and other chronically ill persons. The study conveniently involved all the 140 registered caregivers in the Kanye programme, but with only 82 caregivers turning up for focus group discussions. The caregivers were grouped in 10 focus group discussions, and all of the 5 CHBC nurses were subjected to one-on-one interviews. Both the focus group discussions and one-on-one interviews with the nurses used two slightly different interview schedules as data collection instruments. The study findings revealed that traditional healers are important players in caregiving of persons with various ailments but their role, position and contribution in the battle against HIV/AIDS is fast waning with time. The government has been challenged to map out strategies of collaboration between the two systems as traditional healers can complement the services of biomedical practitioners in this era of HIV/AIDS.
