WT, this is a classic argumentation against LF, but a girl with a number like 3something wrote in the Liver-Flush forum that she put turmeric powder in the OO/grapefruit mix just to verify. The stones that came out were jellow only in the suface, but not inside. Which answers I think clearly enough to what those doctors say. Besides, just tell me how come all these people (me included) loose symptoms after some LF's. All placebo? I don't think so. Come on WT, are you really against the overwhelming evidence in favor of LF?
