Cold sores and vaseline
Submitted by Miss Rachet
Vaseline petroleum jelly rubbed in as soon as you feel a cold sore developing will reduce the size and duration, and sometimes prevent it entirely. Keep the spot covered with Vaseline until it has healed. It will be less painful, and less apt to crack and bleed as it heals. I used to get cold sores 3 or 4 times a year, haven't had one since using Vaseline. It's important to keep the Vaseline on it. I think it works by depriving the virus of air.
