Cold sores are commonly characterized as recurrent crusting lesions that affect the lips and the mouth. Often, cold sores are caused by herpes labialis – a viral infection of the mouth. Cold sores clinically represent a fluid-filled blister-like lesion that is highly contagious. The outbreak of the blisters leads to ulcer formation that is tender to touch. Often, the ulcers scab, creating an unpleasant crusted surface on the skin around the lips. Typically, the treatment of cold sores includes a full course of topical antiviral therapy that lasts for at least ten to 12 days.

However, there are alternative treatments that have proven to be active and soothing as compared to traditional medication therapy. One such treatment is the use of essential oils. Essential oils are natural extracts of herbs and plants that have fewer side effects as compared to the antiviral drug.
