I would hope it is inexpensive. As a tea it may help but I do not know. Check with your local natural path.
Artemisinin has been widely used for malaria, so it is not a new drug. But it is not without risk.
My husband was prescribed artemisinin for what was called Lyme disease and within 5 weeks, his liver failed. He survived, but his bilirubin went up to 58 before it went down in 3 months. The artemisinin was the only new thing he was taking.
Be sure to keep up with liver panel bloodwork whenever taking new medicines, including powerful herbs.
