Fever Blister or Cold Sore

Whenever I notice that I have a "fever blister" or "cold sore" starting to form around my lips I go to our medicine cabinet and get a Lysine tablet. I take one each day until the sore disappears.

Lysine is one of the amino acids which we use to make proteins. I have no idea why extra Lysine helps get rid of the sore. Lysine tablets can be found in the grocery store or pharmacy where vitamins and minerals are found.
