P.S. With evaporation you will absorb about 12% to 14% through the skin. I suspect one would absorb a higher percentage if you use grapeseed oil, olive oil, coconut oil with the Iodine or wrap the area, if possible with plastic or large bandaid. So 100 MILLIgrams of elemental Iodine by itself, painted on, would give you 12mg to 14 mg's through your skin.
