i had thought for a long time that Colloidal Silver would be effective but never got a confirmation on that till now. this is good, because CS doubles for Iodine in the body by performing many of iodine's extrathyroid functions like immune system enhancement and tissue repair.
i am not surpised about diet. i think the Iodine protocol and eating, wearing, and swishing some quality oils is all it would take. avoidance of mercury and fluoride is essential as well.
