"Scientists found that histatin, a small protein in saliva previously only believed to kill bacteria was responsible for the healing."
"Some salivary proteins have even been found to even neutralize the HIV virus."
I do not recommend just licking your lips, either. The important part is to apply a natural lip balm such as Palmer's Cocoa Butter right afterwards.
