there is no danger in oilpulling.
as for iodine, there was in the 1920's an indian man who studied in england,
he got very sick, was about to die, when he spent some time on the coast of france
where they happened to burn seaweed for potassium i think. Staying there healed him of his maledy, and he as he was a medical student, began to find what exactly healed him. He found out about the Iodine in the seaweed and became a Iodine prophet. however, in the years to come, he found out that not all his patients responded well to iodine, even if they had similar diseases as others who got themselves healed. Confused he went to a psychic medium, unknown at that time. the medium was Cayce and he told how Iodine had a toxic character responsible for the uneven results in people. The doctor was told how to detox it and the results were peachy, everybody happy, unill one day when the product went off the market, and the procedure of detoxifying seemed lost. Caycy staked his life as a medium on the fact that iodine BALANCED the thyroid, and other glands, he never had someone tell him the cure did not heal them.
