- Description: The main aim of this study was to examine the meanings attached by locals to medicinal plants in Kabokweni, Mpumalanga and how such meanings tend to shape the character of local struggles over access to, use and even commercial benefits of medicinal plants. This study draws its theoretical schema from political ecology, especially ethnoecology where the goal is to elucidate environmental conflict, most especially in terms of contestations over knowledge, power and practice, as they relate to the meaning and control of medicinal plants in Kabokweni. The study, therefore, recognises the complex interconnections between nature and society through a careful analysis of what one might call the forms of access and control over resources and their consequences for environmental health and sustainable livelihood. In-depth interviews, oral histories and non-participant observation were used to collect data and thematic analysis was used to analyse the data into meaningful themes according to the research questions and objectives of the study. The study found that Swati medicinal plant names are not subjective, but depend on socio-cultural and pragmatic perspectives, and meanings shape local struggles over medicinal plants in Kabokweni. Four underlying discourses were identified from the analysis of local narratives on the meanings and uses of medicinal plants. Each discourse offered a noticeably different concept of medicinal plants and people-plant relationships. Firstly, the ‘sustainability discourse’ referred to the role of foresters and environmentalists in sustainably managing plant resources. Secondly, the ‘livelihood discourse’ was entrenched in the local culture and economy. Thirdly, the ‘knowledge discourse’ conceptualises medicinal plants predominantly in terms of species richness and natural processes, while the ‘economic discourse’ emphasised the economic potential of medicines derived from plants as their major concern. Powerful social actors who influenced decisions about use and management of indigenous medicinal plants controlled these discourses. Finally, the study argues that rural communities would continue harvesting natural resources, even if illegally. Hence, to avert conflicts between indigenous actors and environmental agencies, communities need to be integrated into management programs, so they can be aware of some crucial issues such as sustainable harvesting of medicinal plants. , Thesis (MSoc) -- Faculty of Social Science and Humanities, 2020

- Description: Use of traditional medicinal plants (TMPs) during pregnancy, labour and delivery is common globally although evidence on their therapeutic effectiveness and safety is scarce. Research relating to indigenous practices and utilisation of traditional medicinal plants by childbearing women during pregnancy in Makoni District, Zimbabwe was carried out. The study included identification of culturally important indigenous knowledge (IK) practices and TMPs used by pregnant women in order to understand how such plants and practices may affect maternal, foetal, labour, and infant outcomes. Four hundred questionnaires were distributed to postnatal mothers in Makoni District, aimed at obtaining information on IK practices associated with utilisation of TMPs by childbearing women during pregnancy. In addition to this, five focused group discussions were carried out between September 2016 and December 2017 with 66 traditional healers from Makoni District. Documented information included names of utilised plants, plant parts used, dosage, methods of preparation and administration, and reasons for use. Voucher specimens of the utilised plant species were collected. Brine shrimp lethality test was used to evaluate potential toxicity of the documented plant species. The collected data were analysed used Epi info version 7.1 and SPSS version 16.5. Quantitative data revealed that 168 (42.0percent) of pregnant women in Makoni District use TMPs and 95 (23.8percent) used traditional practices (including elephant dung) for maternal and childcare. Among the women who used TMPs were those who experienced precipitated and prolonged labour. Correlation was found between demographic factors and utilisation of TMPs. For example, being a Christian was significantly associated with using TMPs with relative risk (RR) value of 8.9. Postnatal mothers who used TMPs during their pregnancy were 82.0percent less likely to have their membranes ruptured artificially, RR = 0.2 and more likely to experience late decelerations during active phase (RR = 2.8) than those who did not use TMPs. The differences between those who used TMPs and those who did not during pregnancy and labour, showed no significant differences in infant outcomes. The ethnobotanical survey revealed that a total of 47 plant species from 27 families and 13 non-plant products were used as herbal, complementary and alternative medicines (CAM) by pregnant women. More than half of all the documented plant species (59.8percent), belonged to the Fabaceae (19.1), Asteraceae, (8.5percent), Convolvulaceae (6.4percent), Asparagaceae, Euphorbiaceae, Malvaceae, Rubiaceae, Vitaceae and Xanthorrhoeaceae (4.3percent each) families. The most used plants were shrubs (40.4percent), trees (27.7percent), climbers (17.0percent), herbs (12.8percent) and a grasses (2.1percent). The most used plant parts were roots (61.7percent), leaves (25.5percent), fruits (12.8percent) and bark (10.6percent). A total of 26 medical conditions were treated with the majority of medicinal plants used to dilate or widen the birth canal (55.3percent) and to augment labour or speed up the delivery process (46.8percent). Interviews with traditional healers revealed that 14.9percent of the documented herbal medicines were used to guard against witchcraft and to prevent the infants’ illnesses. Other major uses of herbal medicines during pregnancy included their use to lower blood pressure or hypertension during pregnancy (12.8percent), to prevent caesarean section (10.6percent) and to loosen or relax muscles during pregnancy (8.5percent). Widely used non-plant products included soil of a burrowing mole (relative frequency citation (RFC) value of 0.61), elephant dung (RFC = 0.59), wasp nest (RFC = 0.32) and soap (RFC = 25). The majority of these non-plant products (22.8percent) were used to dilate birth canal (7.6percent) and augment labour (15.2percent). None of the twenty-five species with (RFC) > 0.05 evaluated for potential toxicity were categorised as toxic, but Albizia amara, Datura stramonium and Ricinus communis were categorised as having medium toxicity levels, nine species as having low toxicity levels while 13 species were categorised as non-toxic. This study provides valuable insights into the use of medicinal plants used by women during pregnancy, labour, delivery and post-delivery in Makoni District, Zimbabwe. Medicinal plants play an integral role in the provision of basic health care in Zimbabwe. However, the brine shrimp lethality test results categorised some of the prescribed species such as Albizia amara, Datura stramonium and Ricinus communis as having medium levels of toxicity and this is a cause of concern regarding utilization of TMPs during pregnancy. Therefore, TMPs used during pregnancy should be subjected to detailed phytochemical, pharmacological and toxicological experiments aimed at identifying some of the potential toxic compounds and side effects associated with intake of TMPs and associated herbal products. , Thesis (PhD(Nursing)) -- Faculty of Health Sciences, 2020
