Essential Oils for Cold Sores

Also referred to as “fever blisters”, cold sores are inflamed blisters caused by the herpes simplex virus (HPV). They are often found on the mouth and lips but can also appear on the nose, fingers, and cheeks.

When you get a cold sore, the likelihood of getting a second one is very high. Changes in hormones, too much exposure to the sun, and stress can trigger HPV to create another sore.


A few days after the cold sore appears, it breaks and oozes after which a yellow crust develops. In the end, the crust falls off and gives way to healthy skin underneath. Some of the cold sore triggers include fever, stress, certain foods, colds, allergies, sunburns, and menses.

Cold sores are relatively harmless except for HIV/AIDS patients whose immune systems are low. In rare instances, the infection spreads to the eye and affects the vision or spreads to the brain and causes encephalitis and meningitis.

Over-the-counter medications deal with cold sores but due to their side effects, more organic options are now preferred.
