I also bought several bottles of sweet wormwood because of the anti-cancer effects. It is listed as artemenisin extract. I have a high probability of a mutated gene that increases risk of colon and liver cancer. A sibling had it and has been battling cancer for over a year. I was refused a dna test to verify I have the mutated gene as well, so screw them, I'm doing my own thing. Chemo has been very rough on my sister. Ill pass on chemo. Buy from independently verified and reputable supplement manufacturers. As listed above, I also take quinine and zinc.
