Cold Sore Treatment.

What the gurus are saying

The evidence on whether this treatment actually shortens cold sore healing is mixed, with some studies showing benefit and others finding no real effect. Those who have tested it note that even when it does help, the difference amounts to roughly one day shorter, and the required application schedule of five times daily makes it a lot of upkeep for a fairly small payoff. For people who get cold sores often, the time and cost may not justify the modest results.
