I also take GCG often, but I use it mainly to crush the Gallstones before I do a flush. I also take Chinese Bitters to clense the liver. I never got any tooth ache from these herbs but I know that Julia Chang sells a special herb for problemetic teeth. (http://www.sensiblehealth.com)
Do you know, by the way if the gentian in the Chinese Bitters are enough to kill off parasites or if I'll definatley need to do another parasite clense?
