Yeah, it's probably not a bad idea to keep going for now so you can really see if anything comes out. I have used the Clark herbs, also have used humaworm, also have used some of MH's anti parasite herbs, can't say what is best I have had varying results, I think they all work pretty well. Normal hospital tests will miss most parasites, not sure about candida, but I think mainstream doctors are pretty useless for these type of problems. There are some good candida tests, never tested myself as I self-diagnosed myself with candida.
