For many centuries, plant species have been used by local and indigenous communities as part of their culture and traditions for the preparations of medicines to treat, both human and animal diseases. Local and Indigenous communities are culturally distinct ethnic groups with a different identity, culture, and traditional expressions from the national society, and draw their existence and survival from their local resources or environment [1]. Furthermore, indigenous, and local communities are socially and culturally extinct from the dominant society and often times regarded as vulnerable and disadvantaged by the modern society development processes [2].

Harvesting of medicinal plants in the wild has an impact on sustainability of medicinal plants, which leads to the need for intervention in terms of conservation strategies. Siphonochilus aethiopicus, commonly known as African ginger or wild ginger is used to cure a variety of health conditions/illnesses, such as coughs, colds, asthma, nausea, headaches and pains. This study explored the potential role of indigenous knowledge on the uses, sustainability, and conservation strategies for African ginger among two communities in Mpumalanga province. Qualitative method entailing in-depth interviews were used for this research. We used a non-probability sample (snow-balling) to recruit ten (10) participants that comprised of four traditional health practitioners, four knowledge holders and two herbalists, considered as experts on African ginger in the study area. The data was analysed using thematic analysis. The diverse indigenous knowledge on the uses of African ginger were divided into two categories (diseases and spiritual/cultural purposes) among the local communities. African ginger is indigenous to South Africa and the plant species in the wild is mainly lost to commercial trade. As revealed by the participants, the multiple uses of African ginger are major contributing factors exacerbating the demands for the plant. The uses of African ginger have resulted in the scarcity and possibly extinction of this plant species in the wild, which remain a major concerns to several stakeholders especially traditional health practitioners. Harvesting of the rhizomes of African ginger is recommended instead of the root given the relative ease and higher chances for survival and regeneration. To ensure the sustainable utilisation of African ginger, its cultivation was recommended by the participants. However, there is a need for further intervention to assess how the community members can be assisted with developing and adopting indigenous conservation protocols for the continuous sustainability of African ginger. In addition, it is pertinent to strongly discourage the indiscriminate destruction of natural habitats and create more awareness on the importance of designating protected areas among local communities.

Siphonochillus aethiopicus, known as African ginger, is indigenous to South Africa and has multiple traditional uses in health to treat human diseases. The multiple traditional uses of African ginger have exacerbated the over-harvesting of the plant species from the wild for trade on the traditional medicine market. The wild populations of African ginger have almost completely depleted from the wild and a few African ginger cultivation sites have been established in South Africa, to conserve the plant species. The aim of the study was to compare the major chemical markers of the cultivated and wild harvested African ginger from Mpumalanga using Liquid Chromatography-Mass Spectrometry (LC-MS). The Council for Scientific and Industrial Research (CSIR) wild-harvested African ginger dated 2010 was used as a reference sample for comparison purposes. The LC-MS data generated from the ethanol extracts of the cultivated African ginger detected the presence of 4,4a,5,8a,9-tetrahydro-3,5,8a-trimethylnaptho[2,3-b]furan-8. This chemical marker was also detected in the wild harvested African ginger as compared to a previous study, which auto oxidised in the referenced sample over time. This study supports the efforts to conserve African ginger through cultivation for further development in commercialisation.
