Well, after my second Humaworm cleanse, I pulled out 12 6 inch ascaris (round worms)and one 13 incher and tons of flukes. I used a chop stick to investigate. I also eliminated a tape worm. They are all parasites. lol. you can see my photo's on this forum if you don't believe me which I think you do. But, mine were all dead from the Humaworm cleanse that I did. They did not have a chance to wiggle again, EVER! Donna
