Re: heavy metals in Algin. Since Algin is a mercury sponge, it seems to me that a person using Algin - even if there were trace amts. of mercury in it already, should have no mercury absorption problem from the Algin, as Algin, being a sponge like it is, would hang onto the mercury as well as pulling mercury from the person's system. I do not use Algin because of it being a seaweed, I am afraid that it will contain trace amounts of iodine - even if the iodine has been removed, and iodine, I think, causes problems with my autoimmune thyroid. Therefore, I use Bentonite clay with psyllium. The Bentonite clay does contain aluminum, but they say that because of the charge on the aluminum, it is held by the oppositely charged clay and not distributed to the body. In fact, the clay is supposed to detox. aluminum from the body. It all has to do with the electrical charge in the clay and in the body and the heavy metals. I certainly stand to be corrected on that if necessary. Because if this is not true, I certainly do not need any more heavy metals in my body. I have also started using the clay foot baths. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
