How to treat cold sores?

A volatile solvent: Many times a herpetic (cold sore) lesion can be aborted if caught in the premonition phase (when you feel the burning sensation) by the topical application of a volatile solvent such as ether or chloroform. I should be applied topically with a q-tip and sparingly. Dab it with the solvent three or four times and repeat a few hours later. If an ulcer forms, topical antiviral agents are needed.

Valtrex, (valacyclovir) etc.: Agree w dr.Ryan. Here are more options: melissa officinalis or lemon balm (cream) expedites healing of cold sores. It can reduce healing time by half. Studies also show that regular use can help v recurrences. Brief supplementation with lysine 1, 000mg orally three times a day at the onset, can also hasten healing. Your physician can prescribe oral valtrex (valacyclovir).
