Hi. I'm sure not as experienced as the majority of people here at this website as I just completed my first flush. But, I did get loads of stones out with Dr. Clark's recipe. I also just started on Chinese Bitters and the other one (coptis or something like that) from www.sensiblehealth.com. I hope to do my 2nd cleanse soon. In the meantime, I would think taking these 2 herbs for at least a month would be extremely helpful in helping dissolve stones. Julia, at same website, could tell you how long to take them. She's extremely knowledgeable. Be prepared, however, these herbs are really bitter.
