In brief: No
Cold sores are caused by a herpes virus.
There is no cure for viruses, just treating the symptoms and pain until the resolve themselves(10-14 days). Benzoyl peroxide may dry them or crust them over. There are medication (oral and topical) that will help. Also, some supplements and Amino Acids that have been shown to make them go away quickly.
