well I heard of that theory from Doc too but I have different opinion on why liver is making stones, I dont think liver will make toxic stones to protect it self from parasites, if so you shouldn't feel good after you do LF, you should actually feel more sick after the flush but thats not the case, Ive done flushes without parasite cleanse and still felt great. I believe liver does not release bile because of parasite infection. liver stones are not more than just concentrated bile
