Abstract
Several communities in developing countries derive substantial part of their livelihood needs from alien plants cultivated and managed in home gardens. The aim of this study was to assess useful alien plant species cultivated and managed in home gardens of Limpopo province in South Africa. Semistructured interviews, personal observation, and guided walks with 300 participants between January 2015 and December 2016 were employed to obtain data on names of alien plants cultivated in home gardens and their use categories. A total of 101 plant species belonging to 44 families were recorded from the study area. More than half of the species (66.3%) belonged to 14 families, Fabaceae, Asteraceae, Rosaceae, Solanaceae, Lamiaceae, Anacardiaceae, Poaceae, Amaranthaceae, Apocynaceae, Brassicaceae, Cactaceae, Euphorbiaceae, Moraceae, and Myrtaceae. Twenty-six use categories of alien plants were identified in this study with the majority of species (75.2%) used for medicinal purposes, followed by ornamental (33.7%), edible fruits (24.8%), spices (16.8%), vegetables (16.8%), shade (11.9%), beverages (10.9%), construction materials (8.9%), firewood (7.9%), and hedge (7.9%). These findings corroborate the existing body of knowledge emphasizing the importance of plants grown and managed in home gardens to the livelihood needs of local communities.

Abstract
Elaeodendron transvaalense is a plant species, which is in high demand as a herbal medicine in southern Africa. This study critically reviewed the medicinal applications, phytochemistry and pharmacological activities of E. transvaalense. The literature on medicinal applications, phytochemical, and pharmacological activities of E. transvaalense, was collected from multiple internet sources including Elsevier, Google Scholar, SciFinder, Web of Science, Pubmed, BMC, Science Direct, and Scopus. Complementary information was gathered from pre-electronic sources, such as books, book chapters, theses, scientific reports, and journal articles obtained from the University library. This study revealed that the species is used as herbal medicine in 62.5% of the countries where E. transvaalense is native in southern Africa. It is mainly used as herbal medicine for diarrhoea, menorrhagia, stomach aches, skin infections, inflammations, and rashes. Phytochemical compounds identified from the species, include flavonoids, peltogynoid, phenols, proanthocyanidins, tannin, and triterpenes. Ethnopharmacological research revealed that extracts and phytochemical constituents isolated from E. transvaalense have antibacterial, antifungal, anti-HIV, anti-inflammatory, antioxidant, antiplasmodial, anti-protozoan, anti-pyretic, hypoglycaemic, larvicidal, cytotoxicity, and mutagenic activities. Elaeodendron transvalense should to be subjected to detailed phytochemical, pharmacological, and toxicological evaluations aimed at correlating the medicinal uses of the species with the ethnopharmacological properties of the species.

Abstract
BACKGROUND Studies focusing on plants used medicinally to heal and manage rhinitis are very scarce in Africa and elsewhere. OBJECTIVES To document plants used by traditional healers (THs) in the treatment and management of rhinitis and related symptoms in the Limpopo Province of South Africa. METHODS Data was gathered using a semi structured interviews with 105 THs in the Limpopo Province, supplemented by field expeditions for plant specimen collection and observation. RESULTS 63 plant species from 59 genera distributed across 40 botanical families, mainly the Asteraceae (7 spp.) and Euphorbiaceae (6 spp.) were therapeutically used by THs. Overall, 77 herbal recipes (87%=mono and 12.9%=poly), mainly prepared from roots (55.5%) and leaves (19%) were recorded. Most of these recipes were processed via pounding (59.7%) and boiling (20.7%). Oral (44.1%) and nasal (33.7%) was the preferred modes of dispensing remedies by THs. Artemisia afra, Clerodendrum ternatum, Cryptocarya transvaalensis, Enicostema axillare, Kalanchoe brachyloba, Lasiosiphon caffer, Lippia javanica, Schkuhria pinnata, Securidaca longepedunculata, Spirostachys africana, Stylochaeton natalensis and Zanthoxylum capense were the most widely used and preferred species for treatment of rhinitis and/or related symptom by all questioned THs. CONCLUSION This study is the first to document plants used traditionally to treat rhinitis in Africa. Therefore, it provides a baseline data on the plants used to heal rhinitis in the Limpopo Province. Finding of this study can be used as apedestal for further investigation in to effective plant-based anti-rhinitis drugs.

Abstract
We provide details of 306 plant species used to treat and manage respiratory infections and related symptoms in South Africa. About a third of the documented species belong to four plant families, namely the Asteraceae (15.7%), Fabaceae (6.1%), Lamiaceae (5.6%) and Amaryllidaceae (4.6%). An overwhelming majority of documented species are used as medicine to treat tuberculosis (40.2%), cough (36.6%), fever (29.1%), chest complaints (28.8%) and cold (23.2%). The potentially bioactive phytochemical compounds and associated pharmacological properties of the documented plant species are also provided. This data demonstrated strong correlation between phytochemistry, pharmacological properties and medicinal uses of more than three quarters (80.1%) of the documented species used against respiratory infections and related symptoms. Data of this nature can be used to identify research gaps on ethnomedicinal uses, phytochemistry and pharmacological properties of plant species used as herbal medicines.

Abstract
To the best of our knowledge there are presently no ethnobotanical surveys focusing on the utilisation of herbal remedies for asthma in South Africa. The present study is therefore an attempt to fill this gap in knowledge. A total of 140 Bapedi traditional healers (THs) practicing in the Capricorn, Sekhukhune, and Waterberg districts of the Limpopo Province (South Africa) were queried using semistructured questionnaires, supplemented by field observations during face-to-face interview. A total of 104 medicinal plant species (92 indigenous and 12 exotics) belonging to 92 genera, distributed across 54 botanical families, mostly the Asteraceae and Fabaceae (18.5%, for each) as well as Malvaceae (12.9%), were used as antiasthmatics and related symptoms by these THs. Most of the plants were trees and herbs (37.5%, for each), with root (57%), leaf (15.8%), and bark (7.5%), respectively, being the saliently used parts for preparation of remedies. Clerodendrum ternatum, Cryptocarya transvaalensis, Lasiosiphon caffer, Enicostema axillare, Mimusops obovata, Sclerocarya birrea, and Stylochaeton natalensis were widely used and valued by all THs across the surveyed districts. Furthermore, these taxa also scored both the highest use value and fidelity level indexes as asthma therapies. Overall, the larger number of species documented in the present study is recorded for the first time in literature as asthma and/or related symptoms remedies. Our study finding generally contributes towards an establishment of South African database of herbal therapies used traditionally against these conditions.

Abstract
BACKGROUND Plants used for medicinal purposes are very common feature in Bapedi traditional healer's home-gardens, but information about their diversity and application is not available. MATERIALS AND METHODS To investigate medicinal plants found in Bapedi healer's home-gardens, 51 traditional health practitioners were interviewed using a semi-structured questionnaire in 17 municipalities of the Limpopo Province of South Africa, during the first half of 2013. RESULTS A total of 43 plant species (67.4% indigenous and 32.5% exotics) from 32 families, mostly from the Asteraceae and Apocynaceae (9.3% each) were documented. Species cultivated in home-gardens were used to treat three major groups of ailments that include sexually transmitted infections (44.1%), chronic diseases of life style (44.1%) and reproductive ailments (32.5%). The exotics Catharanthus roseus (54.9%) and Carica papaya (15.6%) was the most cultivated. Threatened (11.6%) and protected (6.9%) species are also present in home-gardens, mostly due to their unavailability in natural areas. CONCLUSION This study concludes that the practice of cultivating medicinal plant species in home-gardens is a positive development that in the long term will sustain both species and accompanying indigenous knowledge, as well as preserve the cultural identity of the Bapedi.

Abstract
BACKGROUND The global burden of sexually transmitted infections (STIs) is a major concern to the World Health Organization (WHO). OBJECTIVE To document STIs treated by Bapedi traditional healers and their methods of diagnoses in the Limpopo Province, South Africa. METHODS A semi-structured questionnaire with closed and open-ended questions was used to collect data from 34 traditional healers, during a face-to-face interview. RESULTS Five seemingly dissimilar STIs; gonorrhoea, chlamydia, HIV/AIDS, nta (Bapedi-terminology) and syphilis were identified as being treated by Bapedi traditional healers. With the exclusion of HIV/AIDS, all STIs are known by healers via their vernacular names. Not all of the recorded STIs are treated by all the questioned traditional healers. Generally, diagnosis of these infections was based primarily on the presentation of symptoms and certain behavioural traits; mostly unprotected sexual intercourse with multiple partners. CONCLUSION The current study concludes that Bapedi traditional healers play an important role in the treatment STIs in the Limpopo Province. Of concern is their diagnosis which is based primarily on the presentation of symptoms and behavioural traits, which are not always accurate indicators. Thus, to make their contribution to the treatment and management of STIs beneficial, they have to receive elementary training in diagnostic methods particularly for HIV/AIDS.

Abstract
BACKGROUND The ethnic usage of exotics and indigenous problem plants is a highly debated topic, as legislative requirements over-shadow their potential medicinal value, particularly to treat sexually transmitted infections (STIs). Limited information exists regarding their medicinal value among the Bapedi. OBJECTIVES To ascertain the importance of exotics and indigenous problem plants in the treatment of STIs, a major global primary health care challenge. METHODS A field observation and semi-structured questionnaire focussing on species diversity, types of STIs treated and medicinal preparation as well as application was used to collect data from 34 traditional healers. RESULTS Seven exotics and three indigenous problem species were identified. These species were used to treat four STIs; with Catharanthus roseus illustrating its dominance in the treatment of gonorrhoea. Some medicinal species used by Bapedi traditional healers have been validated through scientific research or through their extensive use by various cultures in South Africa and other parts of Africa. To the best of our knowledge Alternanthera pungens, Caesalpinia decapetala, Cinnamomum verum, and Citrullus lanatus are reported for the first time in the treatment of the investigated STIs. CONCLUSIONS Exotic and indigenous problem species constitute an important component of the STIs treatment protocol. Their utilization by Bapedi cautions against the narrow-minded approach of indiscriminate eradication, as these species can play a significant role in the primary health care needs of socio-economic vulnerable people.

Abstract
The present study was aimed at documenting medicinal plants used for the treatment of tuberculosis (TB) by the Bapedi traditional healers in three districts of the Limpopo Province, South Africa. Fifty two traditional healers from 17 municipalities covering Capricorn, Sekhukhune and Waterberg districts were interviewed between January and July 2011. Twenty one medicinal plant species belonging to 20 genera and 18 families were documented. The majority (61.9%) are indigenous and the rest are exotics, found near homes as weeds or cultivated in home gardens as ornamentals or food plants. Hyacinthaceae, Moraceae and Rutaceae families were the most represented families in terms of species numbers (9.5% each). Herbs and trees (38% each) constituted the largest proportion of the growth forms of the medicinal plants used. Tuberculosis remedies were mostly prepared from leaves (34%) followed by roots (21%). The therapeutic claims made on medicinal plants used to treat TB by the Bapedi traditional healers are well supported by literature, with 71.4% of the species having antimicrobial properties or have similar ethno medicinal uses in other countries. This study therefore, illustrates the importance of medicinal plants in the treatment and management of TB in the Limpopo Province, South Africa.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE This paper provides ethnobotanical information on medicinal plants used to treat diarrhoea in the Limpopo Province, South Africa. Documentation of this nature usually provides the basis for selecting medicinal plants for future phytochemical and pharmaceutical studies aimed at developing new, effective and affordable plant-derived diarrhoea remedies. AIM OF THE STUDY To record and document medicinal plants used by the Bapedi traditional healers to treat diarrhoea in the Limpopo Province, South Africa. MATERIALS AND METHODS In order to record and document medicinal plants used by the Bapedi traditional healers to treat diarrhoea, 51 healers from 17 municipalities covering Capricorn, Sekhukhune and Waterberg districts in the Limpopo Province, South Africa were interviewed between January and July 2011. Data collected included the names of plants, plant part(s) used, methods of herbal preparation, administration, dosage and duration of treatments. Voucher specimens of the plants used by the Bapedi traditional healers to treat diarrhoea were collected, identified and deposited as future reference material at the Larry-Leach Herbarium (UNIN), University of Limpopo. RESULTS A total of 20 plant species representing 16 families and 20 genera were found to be commonly used by the Bapedi traditional healers to treat and manage diarrhoea in the Limpopo Province, South Africa. The largest proportion of the medicinal plants belonged to the families Anacardiaceae, Asteraceae, Fabaceae and Malvaceae (10% each). The most frequently used species were Punica granatum (39.2%), Grewia bicolor (33.3%), Dombeya rotundifolia (21.6%), Commiphora marlothii (19.6%) and Acacia senegal (13.7%). The roots were the most commonly used plant part (50%), followed by leaves (20%), bark (15%), fruits (10%), pericarp, seed, tuber and whole plants (5% each). Mono therapies based on preparations made from a single plant species were the most dominant (90%). All medicinal preparations were taken orally for 1 week or until diarrhoea subsided. The therapeutic claims of the medicinal plants documented in this study are well supported by literature, with 70% of the species having anti-diarrhoeal properties or are used as diarrhoea remedies both in South Africa and also in other countries. CONCLUSION This study reveals that local communities in the Limpopo Province, South Africa still depend on traditional medicines for basic healthcare; and the use of traditional medicines is still an integral part of their socio-cultural life.
