Just wanted to comment on how Iodine is a GREAT treatment for poison ivy! Get the tincture in drug stores and paint it on the rash...not only does it really help the itch, it also dries it up in a couple of days....the rash does not last near as long!
I also take 7 drops of Lugol's in water a day-not sure if that is helping with it or not, but painting the tincture on is awesome.
I'm suffering with my fourth (or is it fifth now?) batch of poison ivy, and this has really, really helped me a lot!
