Thanks. I have severe chemical sesitivities. I've been colon cleansing for quite some time now and its time to add the liver cleanses. Next is sauna. Do you belong to the Hulda Clark site? I recieved an email from them a few days ago with test results from a typical liver cleanse and it verified what we already know. It was indeed calcified stones and debris. Hulda 1/ Quackwatch -100
