I agree with LoricaLady that you should call and ask for an explanation of what she saw in your release that indicated heavy metals.
I have been giving colonics since the 1990's and have never heard of seeing such a thing. Even with a microscope what distinguishes heavy metal waste? During my colonic training we had access to microscopes to view specimen samples from the waste return of colonic clients to help identify parasites and undigested food matter such as tiny fruit seeds etc., but this is the first time I've heard about heavy metals being visible in a colonic release.
Please follow up here if you get more information. Meanwhile, I'll do some research on this subject.
