20 Natural Remedies for a Cold Sore
Baking Soda
Most people have baking soda sitting on a shelf in the kitchen, so this remedy is at least worth a shot.
Mix a small amount of baking soda with enough water to create a paste. Apply the paste directly to the cold sore, and then allow it to dry. Once the paste is dry let it sit for a few minutes, and then rinse. Repeat every day until the cold sore disappears – usually about 5 days.
