In his article on giardia, Dave McBee gives a graphic description of what this parasite does and his experience with it. He tells first of his attempt to cure the illness with modern medicine, but that left him worse off than he was in the beginning. Following that failure, he consults a naturopath, who, after a brief examination, prescribes a few herbs. This natural method is able to succeed where modern medicine failed. A telling tale, no?
