I was actually busy re-reading the article I posted here previously called: Lots of herb info.... and found this in relation to our concern in finding something to treat brain parasites:
The Chinese Wormwood (Artemisia annua) is known as the sweet variety used to treat the parasite that causes malaria, Plasmodium falciparum. It contains the chemical artemesin, not found in any other species of Artemesia, and is now being viewed as a possible prototype for a new antimalarial medicine. This herb shows a broad spectrum of activity against protozoa and yeast. It is also effective against the liver fluke (Clonorchis sinensis), the blood fluke (Schistosoma japonicum), and the amoeba Giardia and other protozoa. This herb has a low toxicity level, and no side effects have been reported. It appears safe to use, even with heart, liver, or kidney diseases, as well as during pregnancy. The herb is not only effective, but quick-acting. IT IS ABLE TO CROSS THE BLOOD-BRAIN BARRIER, MAKING IT EFFECTIVE AGAINST AMOEBIC INFECTIONS OF THE BRAIN. High doses of antioxidant supplementation should be withheld during treatment of protozoan infection, especially when using A. annua.
