I know I have liver flukes but I have seen other things that I am not sure what they are. One looked like it had legs. Ugh! The good thing about this medicine is it works fast. I LOVE HUMAWORM too but it takes ahile for it to eliminate the bugs or atleast it did for me. In all fairness, my system is eliminating better because I have been gluten free for a over a year now. I highly recommend people to try it and it only costs 6 bucks and shipping. I have spent much more money on other anti parasitic protocols.
