I read on one of the post from Dr. Andrea that you could use chanca Piedra herb to reduce stones 20 drops 3xa day. I think Julie Chang sells this or you could look up chinese herbs on the web and see if you could locate it. Or put out a bulletin on the cure zone and ask. I also read people saying that when they started gold coin grass that they felt great. This also reduces stones.
Hope this helps God Bless
