I had a friend who had cold sores so bad that they were inside her throat, too. She tried L-Lysine, and it worked wonders. Have your hubby start taking it...he can pick it up at a health food store, and they can advise him of the dose. I've never heard of putting the powder on the sore, just of taking the pills. It works as a cure and a preventative!
