Yes, artemisinin is for treating Babesia:
www.personalconsult.com/posts/artemisinin-poor-treatment.html Although Buhner now recommends Sida acuta & cryptolepis and a few other things.
But here is what Buhner said to one person asking why arteminisin:
"Artemisinin is an isolated constituent, cryptolepis is a whole herb, as such it is better for the body and much harder for bacteria to develop resistance to—at this point malaria is developing a rapid resistance to artemisinin but not to cryptolepis. Artemisinin has more side effects, crypto much less—it is much safer for the liver, no side effects have been noted to its use. That is what I would use if I were you."

using arteminisin for adrenal issues, but I haven't launch an all scale attack in looking for that information either.
