HONEY, its magic, got to be the raw honey from amazon, amazing for skin
A research study by Al-Waili (2004) [page references] tested the application of honey to fever blisters, as opposed to acyclovir cream (a prescription antiviral medication).
The study's findings were that the honey treatment performed better. Specifically: "The mean duration of attacks and pain, occurrence of crusting, and mean healing time with honey treatment were 35%, 39%, 28% and 43% better" than when the prescription item was used.

I won't call it bullshit but I am very skeptical of that on the face of it.
