I have a beginning cold sore. Is it possible that hydrogen peroxide and salt a few times daily can help it heal?

Putting an ice cube on it helps too, as long as it's done before it breaks out.

a liberal application of noxema seems to help it from spreading and also takes the sting away

cold sores are caused by the herpes virus. The best think you could put on it is zinc cream to dry it out and protect it from the sun. The less sun the better.
