At the start of my retirement, I attended a "Science Expo" in Sandton. Talking to representatives of the Health Department, I asked what was being done to investigate the herbal and other 'sangoma' treatments, in order to expand (and legitimise) the general availability of traditional medicine. Nothing was being done, and as far as I know, that is still the case. So, if there is so much to "African Knowlege", why isn't it being acknowleged by the African Government?
