Of all the parasite cleanses I have used, Humaworm is by far the best. I think part of the reason is that he uses fresh herbs and makes his capsules per order. His product is much stronger smelling than any I have tried. Also, it it the pure stuff, not diluted with alcohol like tinctures or glycerin or sugar like the syrup based products (I remember taking one of those as a child when my brother had pinworms). I live in the country, go barefoot most of the time, have been know to eat fresh fruits and veggies right off the vine, and I have a bunch of dogs. I could be the postergirl for parasites, but Humaworm has helped me a great deal.
