Cold Sore Treatment.

What the gurus are saying

The gurus who looked at this found the evidence mixed at best. One expert called the benefit negligible, noting it may cut cold sore duration by roughly a day while asking for five daily applications, making it a heavy lift for the payoff. The other found the research itself divided, with some studies supporting it and others not, and suggested it might work in specific cases but without strong confidence. Cost and effort weighed against modest results make this a tough sell for people who get cold sores often.
