Thanks for your reply. I have had Hubby on parasite herbs for 2 weeks then kidney/bowel ones for 2 weeks prior to cleanse. Last weekend we had friends for dinner, we all ate the same food plus he had 2 beers. That night he was violently ill (no one else was) but OK the next day and a few days later felt sicky. I wondered was this because of the herbs? I had no problem with them. I have had a good result with this cleanse 3 tan stones then 20 or so green ones larger than peas then 20 or so green a lot smaller. Should I get larger ones again if I do another flush down the track or now they have gotten smaller so quickly does that mean I have pretty well got them all?
