hi, if you look down at the post called "detox foot bath" you'll see my post about this. I have used this five times so far and do think I feel better, actually I do feel much better. I had the burning sensation in my leg on Sunday and used the foot bath and it went away, having said that my leg is still a bit sore, but I do feel better to answer your post. My kids used it also they do not have any fillings but the water only went light brown with them, with my self the water was dark brown/black !!!!! ...Yukk! <img src="/ubbthreads/images/graemlins/smile.gif" alt="" /> I am going to keep using it as I think it can only do some good.
