Best and fast home remedy for cold sore ?
Yes ! Mens stiptic pencil. Get it at Walgreens. Used for Knicks from shaving. Wet it, break a tiny piece off and apply to sore. It does sting until it dries but that just means it working by drawing the gunk out.
Home remedy? If you have "Campho Phenique" at home... that works. Abrieva works better though.
