I beleie the offending product was made in Japan. At any rate they had just changed their process, and a chemical they were using in the extraction was being left in the product. This toxic impurity was what was causing the problem. > Guess there is not enough profit in a natural product to run through the FDA > testing program and get it back on the market. Since it is a natural product, testing should not be necessary. I think the problem is that it is not patentable, so it is cheaper and safer solution to the patented chemicals that are marketed by big companies. Just like CS. Outlawing it was an illegal act by FDA as far as I can tell. Marshall -- The silver-list is a moderated forum for discussion of colloidal silver.
