ABSTRACT

Colophospermum mopane (J. Kirk ex Benth.) J. Kirk ex J. Léonard occurs over a very large region of southern Africa, occupying varying habitats that could account for ecotypic speciation. This investigation statistical analysed the variations in the architecture of the leaflets of C. mopane from the Limpopo Province of South Africa, with the purpose of ascertaining whether natural variability can act as a source of information for investigating ecotypic variation. Leaf morphometric traits, such as leaflet area, length, width, perimeter, pulvinus angle and the acuteness of the apex, were digitally measured and statistically compared for intra- and inter-population variability. Data indicate that the intra-population variation is 35.33% (statistical similarity: 64.67%), while the inter-population (n = 5) variation is 46.67% (statistical similarity: 53.33%).

ABSTRACT

Mopane worm samples, obtained from different districts of the Limpopo Province of South Africa between April and July 2018, were investigated for the incidence of microbial flora. Over a period of ten weeks, samples consisting of market-obtained, field-prepared and sun- dried worms, were evaluated. It was revealed that after cooking at 89- 93°C, the microbial population was reduced to less than 9 000 CFU/g. The most prominent microbial populations cultured after cooking were spore- formers. Field-processed worms had a microbial population of 4 × 104 -1 × 108 CFU/g. Bacteria and fungi isolated included Aspergillus niger, Enterobacter aglomerans, Escherichia coli, Micrococcus luteus and Penicillium sp. Total microbial population ranged between 4 × 105 and 3 × 105 CFU/g after cooking. Total bacterial count increased in the sun- dried worms from 3 × 105-4 × 105 CFU/g, while it decreased from 2.0 × 105-1.4 × 105 CFU/g after cooking. This data can be used to generate safety guidelines related to the processing of edible insects, such as mopane worms.

ABSTRACT

Background Sexually transmitted infections continue to be a major health concern in sub-Saharan Africa where antimicrobial drugs are becoming ineffective due to increasing resistance. Many healthcare seekers in lower socio-economic settings depend on invasive alien plants administered by traditional health practitioners to treat sexually transmitted infections. Methods Roots of selected plants were analysed for phytoconstituents using standard methods. Both the disc diffusion model and microdilution technique were used to determine the inhibition zone and minimum inhibitory concentration (MIC) of plant extracts against six clinical fungal strains and standard strain of Neisseria gonorrhoea. One-way ANOVA was used to find significant differences. Results Different phytoconstituents such as alkaloids, steroids, cardiac glycosides, terpenes, flavonoids, tannins and saponins were qualitatively detected, depending on plant species. Acetone extracted the highest number of phytoconstituents in Senna didymobotrya, while methanol revealed most from Ricinus communis. Senna didymobotrya showed significant inhibition against Candida glabrata, C. krusei, C. parapsilosis and C. tropicalis. Dichloromethane extract of Catharanthus roseus and methanol extract of S. didymobotrya demonstrated excellent MIC values of 0.03 and 0.08 mg/mL, respectively, against C. glabrata. Catharanthus roseus, Opuntia ficus-indica and Ricinus communis demonstrated moderate to good antigonococcal activity, with all exhibiting more than 63% inhibition. Catharanthus roseus had the best antigonococcal activity with a moderate MIC value of 0.63 mg/mL. Conclusion Some of the plant extracts demonstrated potency towards clinically isolated fungal strains and against N. gonorrhoea, which validate the notion that some of the species need further pharmacological studies for isolation and characterisation of active compounds.

ABSTRACT

BACKGROUND: Invasive alien plant species (IAPs) are plants that have migrated from one geographical region to non-native region either intentional or unintentional. The general view of IAPs in environment is regarded as destructive to the ecosystem and they pose threat to native vegetation and species. However, some of these IAPS are utilized by local inhabitants as a substitute for scarce indigenous plants. The aim of the study is to conduct ethnobotanical survey on medicinal usage of invasive plant species in Waterberg District, Limpopo Province, South Africa. MATERIALS AND METHODS: An ethnobotanical survey on invasive plant species was conducted to distinguish species used for the treatment of various ailments in the Waterberg, District in the area dominated by Bapedi traditional healers. About thirty Bapedi traditional healers (30) were randomly selected via the snowball method. A guided field work by traditional healers and a semi-structured questionnaire was used to gather information from the traditional healers. The questionnaire was designed to gather information on the local name of plants, plant parts used and methods of preparation which is administered by the traditional healers. RESULTS: The study revealed that Schinus molle L., Catharanthus roseus (L.), Datura stramonium L., Opuntia stricta (Haw.) Haw., Opuntia ficus- indica, Sambucus canadensis L., Ricinus communis L., Melia azedarch L., Argemone ochroleuca and Eriobotrya japónica are used for treatment of various diseases such as chest complaint, blood purification, asthma, hypertension and infertility. The most plant parts that were used are 57.6% leaves, followed by 33.3% roots, and whole plant, seeds and bark at 3% each. Noticeably, most of these plants are cultivated (38%), followed by 28% that are common to the study area, 20% abundant, 12% wild, and 3% occasionally. Schinus molle is the most frequently used plant species for the treatment of various ailments in the study area. National Environmental Management Biodiversity Act (NEMBA) (10/2004) and Conservation of Agricultural Resource Act (CARA) were consulted to confirm the invaders status. Only eight plants (60%) are regulated by CARA (10/2004). Of 10 IAPs, 80% (8 species) are listed in both NEMBA and CARA legislation. Only 20% (2 species) are listed in NEMBA alone. CONCLUSION: Invasive alien plants are utilized by communities to combat various ailments in humans and these plants can help to reduce pressure on heavily harvested indigenous plant.

ABSTRACT

BACKGROUND: Bapedi traditional healers of Blouberg are custodians of indigenous knowledge on medicinal plants of this region. They provide primary health care to a large number of people in the Blouberg area of South Africa. There is concern that this profession is dying out, which may be detrimental to the Blouberg community and to biodiversity conservation in the area. METHODS: Thirty two healers and 30 community members were interviewed between March 2011 and July 2013 around Blouberg Mountain in the Blouberg Municipality. A semi-structured questionnaire was used to elucidate socio-cultural and demographic variables and healing customs of practicing healers. Attitudes to sustainable management of medicinal plants were captured. A second semi-structured questionnaire was used to gather information on community members' views of traditional healers and their practices. RESULTS: Sixty seven percent of interviewed community members visited traditional healers. Female traditional healers dominated (80%) the profession. Sixty four percent of the healers have no formal education, with only 4% having secondary school education. Seventy nine percent of healers see between 15 and 20 patients per month. Clinics and a hospital in the vicinity have resulted in a shift by the community from using tradition-based healing to that of allopathic health care. Most interviewed traditional healers (71%) are in favour of conservation actions to prevent over-harvesting, as 86% believe that indiscriminate collecting is compromising the flora of the area. Most (93%) are willing to use cultivated plants. CONCLUSIONS: State health care has negatively influenced the practice of traditional healing as patients now first consult government health centres before turning to traditional healers. In the past, traditional healing has been ignored because, as an oral history, it could not be included in school curricula or government policy documents. Those traditional healers who learn to write will have the skills to document and safeguard their own knowledge. This can help to prevent the erosion of knowledge around Blouberg's medicinal plants and support the conservation of natural resources in the area. Adult learning programmes might therefore be worth implementing amongst healers.

ABSTRACT

The increasing prevalence of overweight and obesity among female adolescents is a global health problem. In developing countries such as South Africa, this increase is often associated with urbanisation and the adoption of a Western lifestyle. Two aspects of the Western lifestyle that contribute to the development of overweight and obesity are a decrease in physical activity levels and an increase in the consumption of energy-dense food, high in fats and refined sugar. Information on the prevalence of increased body fatness in populations in transition is scarce, but necessary for effective planning and intervention. Current indications are that there is a trend towards unhealthy behaviour among high-school girls, globally and in South Africa. Schools can play an important role in the prevention of overweight and obesity among schoolgirls. It is recommended that school governing bodies institute remedial action to prevent weight gain in children, especially girls.

ABSTRACT

BACKGROUND: Relatively little has been researched or published on the importance of peri-urban domestic gardens as part of a household livelihood strategy in South Africa. Due to lack of comprehensive data on peri-urban domestic gardens, their potential value as luxury green space, provision of food, income and ecosystem services to the fast growing urban population in South Africa is not clearly known. The aim of this study was to document differences and similarities in plant use and diversity in domestic gardens of two peri-urban communities in the Limpopo Province that differ in proximity to an urban area. METHODS: Data on plant use categories of 62 domestic gardens in the peri-urban areas of the Limpopo Province were collected in Seshego and Lebowakgomo. Semi-structured interviews, observation and guided field walks with 62 participants were employed between May and October 2012. RESULTS: A total of 126 plant species were recorded for both Seshego and Lebowakgomo. Domestic gardens in the more remote areas of Lebowakgomo were characterized by higher percentage of food plants (47 species, 83.8% of the total food plants recorded) and medicinal plants (31 species, 83.7%). Lebowakgomo domestic gardens were also characterized by higher numbers of indigenous plants (76.7%) showing similarities to the natural surrounding vegetation in terms of plant species. On the contrary, domestic gardens of Seshego on the periphery of the city centre were characterized by higher percentage of exotic species (81.8%) and ornamental plants (73%), with food plants playing a supplementary role. Comparison of the two areas demonstrated a remarkable difference in plant use and composition. CONCLUSIONS: This study revealed that there are differences in utilization of plant resources between households on the edge of an urban centre and those in the more remote areas. Food and medicinal plants play an important role in remote areas; while ornamental plants play an important role in urban domestic gardens. But the collective desire for food, medicinal and ornamental plants by both communities on the edge of an urban centre and those in the more remote areas highlight the importance of plant resources in domestic gardens.

ABSTRACT

BACKGROUND: Bapedi traditional healers play a vital role in the primary health care of rural inhabitants in the Limpopo Province, South Africa. However, literature profiling their social and demographic variables, as well as their traditional healing practices is lacking. METHODS: Convenience sampling were used to identify and select two traditional healers from 17 municipalities (resulting in 34 healers being used in this pilot survey) of the Limpopo Province in South Africa. Information on the social and demographic variables, and traditional healing practices of these healers was gathered from January 2013 to July 2013, using a semi-structured questionnaire, supplemented by field surveys for plant identification and collection used in the preparation of remedies. RESULTS: Males constituted nearly two-thirds of the participants. Forty eight percent of them became healers through the mentoring of another healer, while 38% acquired their traditional healing knowledge from parents and 14% from grandparents. In contrast to this, 62% of the females obtained theirs from their parents, 30% from fellow traditional healers, and 8% from grandparents. A total of 154 plant species were indicated as used by healers in the treatment of 52 health-related problems. A vast majority (89%) of these practitioners reported that prepared herbal remedies do expire, which is a temperature-dependent process. Determinations of the efficacy of remedies by most healers (67%) were via consultation with ancestors (90%). This study also found that none of the interviewees had any knowledge of provincial or national environmental legislation. CONCLUSIONS: The current study has shown that Bapedi traditional healers could play a leading role in both the preservation of indigenous knowledge and the primary health care sector. However, of concern is the traditional methods (via consulting ancestors) employed by most of these healers in determining efficacy of remedies, thus indicating a need for a scientific investigations to establish their safety and effectiveness. Equally, there is a need to educate traditional practitioners' regarding the significance of various conservation legislations in their traditional healing. By addressing these, the national and provincial legislators, medical fraternity as well as environmental agencies will be able to better integrate them in primary health care systems and environmental management.

ABSTRACT

BACKGROUND: Most rural people in the Limpopo Province depend on plant resources to meet their livelihood needs. However, there is insufficient recorded information regarding their use and management. The current study therefore was carried out in selected villages of the Limpopo Province, to close this knowledge gap. METHODS: Information was collected from 60 people residing in two villages, using a semi-structured questionnaire, supplemented with field observations. RESULTS: A total of 47 wild plant species (95% indigenous and 5% exotics) from 27 families, mostly from the Fabaceae (17%), Anacardiaceae (9%), and Combretaceae (9%) were documented. These species were used primarily for firewood (40%), food (36%) and medicine (29%). Significantly used species included Sclerocarya birrea (85%), Combretum kraussii (35%) and Harpephyllum caffrum (35%). Local traditional rules and regulations including taboos, social beliefs and fines are in place to aid in the management of communal resources. However, a significant number (67%) of participants mentioned that they were not pleased with these rules and regulations. CONCLUSION: The current study concluded that plant resources still play an important role in the surveyed rural areas of the Limpopo Province. Furthermore, for sustainable utilization and long-term conservation of plants in these areas the government should assist communities in the management of their plant resources.

ABSTRACT

ETHNOPHARMACOLOGICAL RELEVANCE: Most exotic plants are usually labelled as alien invasives and targeted for eradication. However, some of these exotic plants play an important role in the traditional primary healthcare sector of the Bapedi culture in the Limpopo Province of South Africa. The medicinal uses of most of these species have neither been documented nor their biological activity evaluated. AIM OF THE STUDY: To make an inventory of exotic species employed by Bapedi traditional healers to treat different human ailments in the Limpopo Province, South Africa. MATERIALS AND METHODS: Semi-structured interviews, observation and guided field walks with 52 traditional healers were employed to obtain ethnobotanical data during first half of 2011 on the use of exotic plant species by Bapedi healers to treat human ailments. Based on ethnobotanical information provided by these healers, specimens were collected, numbered, pressed, and dried for identification. RESULTS: A total of 35 exotics species belonging to 21 families and 34 genera, mostly from the Fabaceae and Solanaceae (11.4% for each), Apocynaceae and Asteraceae (8.5% for each) were used by Bapedi healers to treat 20 human ailments. Trees (45.7%) and herbs (37.1%) are the primary source of medicinal plants. Species most frequently reported were used for the treatment of hypertension (35%), diabetes mellitus, erectile dysfunction and gonorrhoea (25% for each). The highest consensus from individual accounts of the traditional healers on the use of exotic plant remedies in this study was noted for the three ailments. These were for Catharanthus roseus (gonorrhoea, 60%), Punica granatum (diarrhoea, 38.4%) and Ricinus communis (sores, 21.5%). Of the 35 exotic plant species recorded, 34.2% are regulated by the Conservation of Agricultural Resources Act (1983) (CARA) No. 43 of 1983 either as worst weeds or invaders. CONCLUSION: The present study demonstrated that exotic plant species play an important part as medicinal remedies employed by Bapedi healers to treat different human diseases in the Limpopo Province. The use of these species as alternative sources of medicinal remedies could alleviate harvesting pressure of wild indigenous plants, thereby enhance biodiversity's region. However, there is a need to formulate an appropriate policy to retain some of the useful medicinal exotics (listed under CARA No. 43 of 1983) within the environment before their medicinal value vanishes as they are eradicated through management strategies adopted by the South African government.
