Lufenuron has helped us greatly with worms, fungus and Candida. My daughter was expelling little red worms for about two months while using Lufenuron! I noticed some thread worms and that I had a lot more energy. However, I am still having a problem with intestinal Amoeba which I believe the Lufeneron does not work on because Amoebas don't have Chitin in their membrane? From my research, Lufenuron has no known negative side effects for humans. I bought mine from owndoc website (from Sarah Vaughter)
Apparently Tumeric will also kill Amoebas and other parasites.
Castor oil packs are also supposed to help greatly!
