If you look at the 108 pages on the web site, you will see the largest gallstone a human can pass; the size of the gallbladder its self! Behind this huge stone cvan be a hand full of stones that were clogging the liver. These often are created in pockets that the liver fluke parasites have eaten in the liver.
I always suggest people to liver flush until NO lrge stones appear, nothing larger than the size of BBs. Otherwise do the superior old medical method of consuming lecithin every night and NEVER EVER make a liver stone again and cure the circulation, the nerves and the brain with the cheapest supplement of them all, soybean lecithin.
