okay, when john G says liver i think he means liver and all the many biliary passages that surround the liver. alot of the stones that cause the "damage" are in fact in the smaller bilary passages leading to the main bile ducts. these passages have the ability to hold far more stones than the liver.(this is not my opinion but what i read from Andreas Moritz )
p.s-90 flushes a an extreme. 90 % of the time 8 to 20 flushes is the norm needed for clear all stones.
