29 Home Remedies to Get Rid Of Cold Sores

22. Make a Cornstarch Paste

Cornstarch is one of the easiest, not to mention cheapest, treatments that can be used for cold sores. Cornstarch has properties that can neutralize pH, which creates a highly acidic environment that the fever blisters thrive on. Placing a cornstarch paste on the sores, which is basically made from cornstarch mixed with water, will soothe any inflammation and lessen the pain that comes from cold sores. Put it on the sores around three times a day to help lessen the common symptoms that come with them.
