A lot of very useful drugs have come from non-Western medicine traditions. Drug companies have people all over South America seeking native folk medicinal plants to check for useful drug activity. A Chinese doctor decided to investigate artemisia, an ancient Chinese medicinal herb as a treatment for malaria with her own random blind trial. It worked so well she won the Nobel Prize for Medicine!
Turns out the plant that Madagascar herbal drug is brewed from.....is artemisia! It might actually work. Works for my wife's undiagnosed lyme-like recurrent syndrome. Once or twice a year she gets debilitating abdominal pain. Western medicine has told her it's all sorts of different things by ruling out other stuff. Only thing that stops it is artemisia.
