Herpes Simplex
"I&#039;m surprised to see any negative reviews, I guess everyone&#039;s body reacts differently and Abreva is no different.

It works for me. I&#039;ve been using it for the past 6 years or more at the first sign I get, usually a tingle or tenderness on the lip. Even if a sore has already formed it seems to quickly stop it in its tracks. Definitely pricey, but the little bottle lasts me years. Love Abreva for doing what it&#039;s advertised to do!"
