Has some effect: The best treatment is laser such as the biolase md laser which will relieve the pain immediately and decrease the normal healing time for the cold sore.

Somewhat: Cold sores are viral infections ( herpes simplex i ) and do not respond to antibiotics. The Amino Acid lysine, is very effective at reducing the time to heal.
