Kathie, you have me very intrigued. What is this "clay"? What is it called, where do you get it, how much do you take and how often. What differences in your overall health did you notice after using it? I assume that the silymarin is found in health food stores and I will look for it there. Same questions regarding dosage as for the above, if you will. I am most interested in hearing your reply. Barb Bates
