I had a surgeon oversee my Liver Flush treatment. He did an ultrasound before the flush and another one the day after, and said the flush cleared almost all the stones. I passed about 75 stones in the first flush. Most were small, marble size or smaller. Five years later I had another gallbladder attack and another surgeon who did the before and after ultrasound. The second flush caused me to pass a stone almost as big as my thumb. The surgeon was amazed at how well it worked and has asked me several times for the recipe to pass along to other patients.
