Herpes Simplex
"This product makes the cold sore worse. It made my one pimple sized cold sores itch and 2 more popped in the area. I have given it a chance in the past (3 more times) but now am convinced that it doesn&#039;t work. ITS THE MOST ADVERTISED ON TV but its JUST A SCAM. Please save your money and try something like tree tea oil to make the blister small and dry."
