Regardless of whether they are "real gall bladder stones," it is clear that whatever they are, they were 1) lodged somewhere in my biliary tract and 2) expelled with both the coffee enema and, in much larger numbers, the liver flush. So whether they were "real gall bladder stones" or not, the flush got them out, and my health improved markedly as a result. I think that's enough to prove liver flushes' efficacy.
