My mother has Hepatitis C, Diabetes, and a very large gall stone. She wants to do a liver/ gall bladder flush but is worried about the large stone getting stuck. (We are not sure how big it is, the doctor just told her it is one of the largest he has seen)I have read that gold coin grass can break up stones, making them easier to pass, but we obviously need to make sure that any herbs, supplements, etc. will be safe for her liver. Do you know if the GCG is safe to use with Hep C?
