My wife E, seen in the context of history, may be at the tail end of those who once knew about the medicinal and food plants of Africa -- as a working knowledge rather than a specialised knowledge. It is interesting, too, that while she knows nothing about some of the things I learnt at school, she knows much about things I know nothing about. Our local urban park cultivates many medicinal and food plants once used by indigenous peoples. I took the photo this morning, of an indigenous Khokhoi tea. I think that this one is a remedy for worms.
