I dealt with the fungus ringworm for a few years, still getting breakouts when I started Iodine two years ago this month.
Not only did all the ringworm clear up, but the major old brown scar on my calf is even UNnoticeable now, and I can TOUCH my husband's (very contagious) ringworm, and not breakout at all.
Iodine is THE bomb! (Wish hubby would take Iodine internally, but...alas)
