Indigenous trade of medicinal plants in South Africa is a multi-million-rand industry and is still highly relevant in terms of primary health care. The purpose of this study was to identify today’s most traded medicinal barks, traditionally and contemporaneously used for dermatological, gastrointestinal, and respiratory tract infections; then, to investigate the antimicrobial activity and toxicity of the respective extracts and interpret outcomes in light of pharmacokinetics. Thirty-one popularly traded medicinal barks were purchased from the Faraday and Kwa Mai-Mai markets in Johannesburg, South Africa. Information on the medicinal uses of bark-based medicines in modern commerce was recorded from randomly selected traders. The minimum inhibitory concentration (MIC) method was used for antimicrobial screening, and brine shrimp lethality was used to determine toxicity. New medicinal uses were recorded for 14 bark species. Plants demonstrating some broad-spectrum activities against tested bacteria include Elaeodendron transvaalense, Erythrina lysistemon, Garcinia livingstonei, Pterocelastrus rostratus, Rapanea melanophloeos, Schotia brachypetala, Sclerocarya birrea, and Ziziphus mucronata. The lowest MIC value of 0.004 mg/mL was observed against Staphylococcus epidermidis for a dichloromethane bark extract of E. lysistemon. The tested medicinal barks were shown to be non-toxic against the Artemia nauplii (brine shrimp) bioassay, except for a methanol extract from Trichilia emetica (69.52% mortality). Bacterial inhibition of bark extracts with minimal associated toxicity is consistent with the safety and valuable use of medicinal barks for local muthi market customers. Antimicrobial outcomes against skin and gastrointestinal pathogens are feasible because mere contact-inhibition is required in vivo; however, MIC values against respiratory pathogens require further explaining from a pharmacokinetics or pharmacodynamics perspective, particularly for ingested rather than smoked therapies.

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, andStylochaeton natalensiswere 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.

Sclerocarya birrea subsp. caffra (Marula) is widely used throughout its natural distribution range by rural populations to meet livelihoods requirements. Every part of the tree, including the fruits, branches, stem and roots, provides goods and services of high cultural, social, and economic importance. Its usefulness and unique properties have encouraged local people to retain S. birrea in communal areas. However, there is a paucity of data quantifying the role of local communities in conserving S. birrea. This study quantifies the role of local communities in protecting S. birrea in 300 randomly selected households in Matiyane Village, Limpopo Province, South Africa. The study found that the majority of the respondents (92%; N = 276) are positive about the conservation of S. birrea. Most importantly, the respondents play a significant role in the protection of S. birrea in the village. Management strategies and factors responsible for the protection of S. birrea in communal land are discussed.

The marula tree (Sclerocarya birrea subsp. caffra), a common species in sub-Saharan Africa, grows naturally in both protected and communal land. Although considerable research has been undertaken on these trees in southern Africa, to the authors’ knowledge, the attitudes of local communities towards the protection of marula trees, particularly in communal land, has not been researched. This study intends to fill this gap in knowledge by examining the attitudes of local people towards conservation of marula trees. Studying the attitudes of people can provide insights on how they behave and how they are willing to coexist with S. birrea. The case study is set in Limpopo Province of South Africa in the villages of Ha-Mashau (Thondoni) and Ha-Mashamba where marula trees grow naturally. To fulfil the aim of this study, door-to-door surveys were carried out in 2018 and questionnaire interviews were used as the main data collection tool in 150 randomly selected households. The study revealed that local communities in the study area had positive attitudes towards conservation of marula trees. Strategies that are used by local communities to protect marula trees in communal land are discussed.
