Not meaning to get off the subject here. Actually we are now chelating our autistic son, or I would say mercury poisoned via immunizations. Right now he is a priority for chelation, as he is doing better all the time. for him we are working with an excellent doctor, all out of pocket, ouch!!!. I haven't done a complete Colon Cleanse yet. I have done a good gall bladder cleanse and I believe that may have addressed the liver also. I passed many Gallstones and a liver fluke, and egg sacs, scary!!!!! I have done several parasite cleanses and seen many parasites, small ones in my stool, and am now doing both a candida cleanse and parasite cleanse. The parasite cleanse does do a good cleaning of the colon. I haven't seen much in the way of parasites with this cleanse which is encouraging. I do know that if my husband is not doing those same cleanses properly we will just continue to be plagued with our problems, as he passes what ever he has to me. We stay at arm lengths away from each other. I think we both need to be cleansed to clear up our problems.
