I found a very interesting interview by author Thom Hartmann where he talks about how many people are now intentionally putting hookworms into their bodies to cure diseases like asthma, Crohn's disease and multiple sclerosis. And there are quite a few studies to back this up. They're all pdf files however, so not sure how to post them. Anyway, here's the link to the interview: http://www.kuow.org/program.php?id=18121 And another link to a report of how the little guys are helping people w/Crohn's: http://cbs5.com/health/hookworm.treatment.therapy.2.1016319.html COULD THEY HELP THOSE OF US w/CFS/Fibro, etc.? Not sure, but this quote is intriguing: "In order to live as a parasite inside the human, the parasite must convince the host's immune system to chill and not try to reject it. With hookworms, they secrete a chemical that distracts the immune system, dampening down its response." Does that mean a th1-th2 shift, or vice versa?
