hi I just read your message and wondered how u know the size of the stone. Oh it is calcified so it showed up on an exray. Anyway, I thought you might like to look at this web site. It has alternative recipies for flushes adding in the use of chinese type herbs and one of them is for breaking down big stones into smaller stones. It also has great info all around esp for hormone issues and liver congestion. it is http://www.sensiblehealth.com Let me know what you think. I haven't tried it yet, but may. It also talks about getting stones stuck in the duct during a flush and what to do. She seems to know her stuff to me. we'll see what others think/know. good luck Lin
