Help, could u give me steps on treating 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 topical 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. Use a topical anesthetic cream when in the ulcer stage.
