    Ethnobotanical survey of medicinal plants used to manage High Blood Pressure and Type 2 Diabetes Mellitus in Bitterfontein, Western Cape Province, South Africa
    (Elsevier, 2016) Davids, Denver; Gibson, Diana; Johnson, Quinton
    ETHNOPHARMACOLOGICAL RELEVANCE: The aim of this study was to identify and document medicinal plants used to manage High Blood Pressure and Type 2 Diabetes Mellitus in Bitterfontein, Western Cape Province, South Africa. METHODS: One hundred and twelve (112) respondents were interviewed between August 2014 and September 2015 through semi-structured surveys to gather data on the percentage of people who had been diagnosed with High Blood Pressure and/or Type 2 Diabetes Mellitus and to determine the frequency of medicinal plant and allopathic medicine use. Twelve (12) key respondents were subsequently selected, using a non-probability snowball sampling method. They were interviewed in-depth concerning their plant practices and assisted with plant collection. RESULTS: Twenty-four plant (24) species belonging to 15 families were identified for the management of High Blood Pressure and Type 2 Diabetes Mellitus. The most frequently reported families were Asteraceae (20.8%), Lamiaceae (16.67%), Crassulaceae (8.33%) and Aizoaceae (8.33%). The remaining (45.54%) were evenly split over eleven families- Fabaceae, Amaryllidaceae, Anacardiaceae, Capparaceae, Geraniaceae, Apiaceae, Convolvulaceae, Apocynaceae, Rutaceae, Asphodelaceae and Thymelaeaceae. The most commonly used plant species overall was Lessertia frutescens (96.55%). The most frequently used plant parts included leaves (57.63%) roots/bulbs (15.25%) and stems (11.86%), mostly prepared as infusions or decoctions for oral administration. CONCLUSIONS: Medicinal plants are widely used by High Blood Pressure and Type 2 Diabetes Mellitus sufferers. They employ diverse plant species to manage both conditions. In addition, some sufferers often use prescribed allopathic medication, as well as medicinal plants, but at different intervals. Despite high usage the plants identified are not currently threatened (Red Data list status: least concern).

    Knowledge Interfaces: Kruiekenners, plants and healing in Genadendal
    (University of Western Cape, 2021) Davids, Denver; Gibson, Diana
    This thesis was informed by what I perceived to be a tense relationship between Western biomedical science and, for example, �traditional� or �indigenous� ways of producing knowledge about medicinal plants used to manage a pervasive condition like Tuberculosis (TB) in South Africa. Hoping to reimagine this relationship and its possibilities, I follow medicinal plants collected from Genadendal through three research spaces with disparate but intertwined knowledge heritages to investigate these tensions but also to tease out how knowledge about locally used medicinal plants is generated and �done� in practice. The first space was at the South African Herbal Science and Medicines Institute (SAHMI) as part of an experiential science project led by scientists who were interested in studying medicinal plants which could potentially provide new sources of safe, affordable, and sustainable medicine for communicable conditions such as TB.

    Materia medica and care : a study of the uses of medicinal herbs and remedies as a form of treatment and negotiating social relationships in Cape Town and surroundings
    (2012) Davids, Denver; Gibson, D.
    This study falls within the framework of the larger multidisciplinary university health initiative (MUTHI) objectives to investigate and document the use of local medicinal plants for the treatment of HIV and symptoms of related opportunistic infections such as tuberculosis, thrush and shingles in the Western Cape. The study stems from twelve months fieldwork in Strand, Western Cape and the collection of plants from Mpoza, Eastern Cape for a variety of reasons. The study ethnographically documents when, under which circumstances and where plants are collected for use.As far as I am aware this is the first anthropological study which "follows" traditional healers in the Western Cape to a site in the Eastern Cape where they collect plants. Seventeen plants were collected from different genera which traditional healers reported to use as treatment for suspected HIV and related symptoms. For each plant I describe the medicinal uses,preparatory techniques and plant parts used as suggested by traditional healers. I also explore healer's aetiologies concerning plants, treatments and the social-material relations which are prevalent in my research settings.

    Traditional health practitioners� perceptions, herbal treatment and management of HIV and related opportunistic infections
    (BMC, 2014) Davids, Denver; Blouws, Tarryn; Aboyade, Oluwaseyi
    In South Africa, traditional health practitioners� (THPs) explanatory frameworks concerning illness aetiologies are much researched. However there is a gap in the literature on how THPs understand HIV-related opportunistic infections (OIs), i.e. tuberculosis, candidiasis and herpes zoster. This study aimed to comprehend THPs� understandings of the aforementioned; to ascertain and better understand the treatment methods used by THPs for HIV and OIs, while also contributing to the documentation of South African medicinal plants for future conservation. The study was conducted in two locations: Strand, Western Cape where THPs are trained and Mpoza village, Mount Frere, Eastern Cape from where medicinal plants are ordered or collected. Semi-structured interviews were conducted with 53 THPs of whom 36 were diviners (amagrirha: isangoma) and 17 herbalists (inyanga). THPs were selected through a non-probability �snowball� method. Data were analysed using a thematic content analysis approach.
