Good post! I've always wondered when reading about " liver stones " threads like this, would this ailment show up in the standard liver function parameters included in comprehensive blood panels? Such parameters are itemized in the first link below.
Also, I'm not sure how much impact they would have on the "stones" ailment, but a number of good "liver support" supplements are out there. Perhaps they might help...? (Second link)
Good liver info from health gurus Dr. Andrew Weil and Dr. Michael Murray in the third and fourth links.
