Don't really know iodine and I've never used it or really researched it's uses, but I found this and thought I should share anyway. Oz, you know more about these things. What do you think?
Tincture of Iodine is another thing I came across. It is not the same thing as Povidone Iodine or Betadine. In fact, there are warnings against using the tincture. It is said to be poisonous and ..."dangerously inflames mucus membranes and if put on a wound or piercing it can result in a toxic level of iodine absorption."
