I do not know the direction you know to go. But I want to share that I fell upon coconut oil from Tropicaltraditions.com and with the first spoon, I had the most severe and longest lasting die-off pain ever. My stomach was totally empty when I took it that night because I had not wanted to eat or drink anything that day. (Tired of the intensity of this parasite fight.)
Also Diatomaceous Earth is very, very good. Their site is earthworkshealth.com. These things won't get rid of big parasites. But they have affect on smaller varieties. I am also now seeing a Chiropracter who is treating me with neurolink. My body has passed some big ones following two of his treatments and I am working closely with him with diet and such. I think he will finish the fight for me. See if you can find a doctor who practices this.
