Artemisia annua has been used in Traditional Medicine for thousands of years but has still not been the subject of the numerous studies required by Western medicine to be able to write that it cures. However, it is well known that Artemisia annua has biological action on numerous parasitic pathologies (malaria, bilharzia (schistosomiasis), leshmaniasis, filariasis, trypanosomiasis, Chagas disease, babesiosis), and viral, bacterial, fungal and cancerous diseases. It has immuno-regulatory, anti-inflammatory, anti-osteoporosis and anti-adipogenic actions.
Clinical trials have shown that it treats uncomplicated malaria and schistosomiasis. See:
