Yes I have tried the malic acid caps. I neevr had any success with the liver flushes. Tried a lot of them too but I never could get my bowels to move...no epsoms was going to move my decripit ole bowels* sheesh* :-(. Could have taken a firecracker in there to get anythng out. I think my liver was so congested it was frozen. Never got any stones per say...did get some bile, but that seemed to make my leaky gut waaaay worse. I gave up on them after a while, but some people swear by them :-) But sorry to get going on that. i tend to be long winded.
