WHAT ARE AFRICAN CONTRIBUTIONS TO GLOBAL HEALTH?

South African medicinal plants in global health

Let us now turn to an example of how African knowledge can contribute to global health: In this podcast, Tanja Hammel and medical anthropologist Diana Gibson discuss two South African medicinal plants. How could the world benefit from the plants’ medical properties? How can we guarantee that indigenous communities will profit from this knowledge? Listen to the podcast – you can find the transcript below this step.

Diana Gibson is Emeritus Professor of Anthropology at the University of the Western Cape, Cape Town, South Africa. As a medical anthropologist, Gibson has done research on the connections between science, ethnobotany, ethnopharmacology, pharmacy, botany, traditional medicine and anthropology, with a focus on medicinal plants in the Cape floristic region.

In this podcast, Gibson shares her expertise on two medicinal plants: cancer bush/balloon pea (Sutherlandia frutescens) and kanna (Sceletium tortuosum). Sutherlandia frutescens is particularly interesting, as it relieves noncommunicable conditions by acting as an immune modulator and has anti-bacterial and anti-cancer properties. Sceletium tortuosum alleviates pain and reduces stress, depression and anxiety.
