Arteminisin must be used carefully, but artemesia annua is different. Arteminisin is a derivative of artemesia annnua - it's a concentrated portion of the active chemicals of the plant. They have removed some of what keeps it actively working on the infection, and the part that helps protect the body. While arteminisin is pretty effective, it can only be used for a short period of time - I think they are still trying to figure out how much and how long it's best used for.
I prefer to use the whole herb, as you don't have to worry about
the enzyme in the GI tract that will prevent it from being effective, even if used long term.
So, it comes down to which version of the herb you wish to use - artemesia annua (whole herb) or the arteminisin (concentrate).
