A nasty cold sore arose on my bottom lip. After 2 days of it annoying me I decided to put a drop of Lugol's iodine on it. Yes, it burned for a few minutes, but, I think it killed it outright. I put another drop on later in the day just to be sure. The next day I noticed it had flattened out quite a lot, then, in a few days a scab peeled off in two very thin layers and my lip looked completely normal. I could not believe it!
