herpes simplex
"I am so happy with this products. Everytime I get a high fever which is usually once or twice and year I always have a break out of fever blisters. I have tried everything under the sun from ice, tea bags, herpicin L, releev, carmex... Anything and it would always take a 3-4 weeks to just see it start to scab. I bought Abreva yesterday morning and it is already at the scabbing stage and I had a fever blister start the day before. I apply every 2-3 hours and its working great! I do make sure the wash and dry hands before and after applying abreva."
