Wow, sounds like you're having a good deal of success!
I have a booklet on the benefits of MSM- and one of the things the author stated was how over a certain amount of MSM daily in the diet actually does kill intestinal parasites. It creates a coating on the intestinal lining which causes the parasites to keep slipping off . Many parasites need to latch onto the intestines to suck up nutrients--- and if they can't latch on- they starve- and/or get flushed out of the body.
MSM is a natural nutrient found in all raw fruits and vegetables. MSM supplements are non-toxic- even in very high doses, and great to take for healing the body's cells and skin/hair tissues-- and also with the added bonus of kicking off parasites ;-)
