A long article about Iodine. It includes on disgusting photo of a person with sporotrichosis like fungal eruptions and suggests these may disappear within 2 weeks when treated with Iodine.Although many texts discuss Iodine and the Thryoid this article says that possible just 3% of the iodine in your body is held by your thryoid (of course when you are not deficient)
The article also offers links to many other great articles on Iodine
