Steve: Just wondering. I have hypothyroidism. Often, I cannot sweat and I get prickly heat instead. I have just read today that mercury replaces iodine on the thyroid. The thyoid does not work without iodine. When mercury replaces iodine, you get hypothyroidism with sypmtoms which I listed on miriam's post. (I forget to mention the fact that you can't sweat as well as you should). Perhaps, if mercury has left your thyroid, and iodine has replaced it, you are now developing an ability to sweat. We are often, as a nation, according to the dr. whose column I just read, deficient in iodine. However, if you are taking Algin, and if that Algin has still got its iodine, (kelp has oodles of iodine), then, as the mercury leaves, iodine will take its proper place, and you will be able to sweat - which is good - it helps you to detox. Russ, does the Algin you sell still have iodine?
