I am a Cheney patient. I have not seen him since early in the year, prior to the XMRV study, but at that time he was recommending that I take one capsule of artesunate (sold as "hepasunate" by hepalin.com...can also be bought from Guilin Pharmaceuticals in China, but apparently is the subject of a tremendous amount of counterfeiting in Asia) on Tues & Thurs mornings and one capful of wormwood solution (from Mediherb) on Mon, Wed & Fri mornings. Don't take either on Sat. & Sun. He recommends that both be taken sublingually (not swallowed) out of some concern that artemisinins can cause drug-induced hepatitis if taken for a prolonged period. For me, sublingual means basically swishing the stuff around in my mouth and gargling with it and then spitting it out after a few minutes. Fair warning, the wormwood solution tastes truly foul and needs to be diluted with water to about 1/3 strength. I am not exactly sure why Cheney recommends taking these artemisinin-related compounds only 5 out of 7 days each week, but this has often been his protocol for treatments that he thinks have immune-modulating or anti-microbial properties. (For example, his protocol for Isoprinosine/Inosine used to be the same, 5 days on, 2 days off.)
I have found this protocol to be helpful in reducing fatigue and flu-like symptoms. It is not a miracle cure, of course, but I definitely feel more fatigued on Saturdays and Sundays when I am taking neither the artesunate nor the wormwood solution.
