cold sores
"Sunday woke up with a tingle on my lip. Took two pills 1 gram each and through out the day I put on Abreva. My lip got swollen a bit but never did it come to a head and burst or leak. By day two in the morning the bumb was significantly smaller and by late afternoon it practically was gone. Day three can't see much of the cold sore except for a sore only and it's not really noticeable. Very happy with the results!"
