Years ago when I came back from India with some 'friends' I tried DE,, and then switched over, can't remember the results. BUT, I do have reservations about DE. Under a microscope it appears like broken glass, or so I've read. If someone doesn't have a thick mucous coating on their intestines, small and large, I am not convinced it doesn't possible get into a fold and cause irritation. You might try brushing your teeth or really gums with it, and look for abrasion or irritation. I've read where the tape worm ingests it and it tears up their insides or even crawling around in it can abrade them to death. And yes, I too would like to know what you find out. thanks, Van
