    The most effective essential oils for cold sores and how to reduce symptoms of herpes with the best cold sore remedy.

    Essential Oils for Cold Sores & Fever Blister

    Cold sores are caused by the herpes simplex type 1 virus. It’s estimated that between 50-80% of Americans carry the virus, but some may never experience a cold sore outbreak.The virus can be transmitted through physical contact, such as touching or kissing.

    Cold sores present themselves in the form of irritated patches of skin, and blisters around the mouth. The first time you experience these symptoms you may also feel swollen lymph nodes, cold and flu symptoms, or headaches. Generally, these symptoms do not accompany every outbreak; the first is usually the worst.1

    Once the herpes simplex virus is contracted, it remains with the individual for life. There is no permanent cure for cold sores, but flare ups of the blisters can be treated through over the counter applications, or naturally at home, with the help of essential oils for cold sores.

    Some individuals prefer to use natural remedies for cold sores, rather than turning to pharmaceutical treatments, which may contain harsh chemical ingredients. Of the various natural or homeopathic cold sore remedies, using essential oils for a cold sore has become increasingly popular because they’re affordable, effective and safe to use topically, when diluted with carrier oils.

    Essential oils for virus treatment, such as herpes simplex type 1, work well because of their antibacterial, antiviral, and anti-inflammatory properties.

    Cold Sore Remedies at Home

    To create a preventative face wash, combine 8 drops of lemon essential oil, 8 drops of eucalyptus essential oil, ¾ cup of water, ¼ cup of castile liquid soap, 4 drops of vitamin E oil, and ½ Tsp. of jojoba oil. Mix well and pour into a clean soap dispenser or foaming soap bottle.

    If any DIY cold sore remedy causes an allergic reaction or skin irritation, halt treatment immediately and speak to a physician. Individuals with sensitive skin should always conduct a patch test before applying natural cold sore remedies to cold sores. When using essential oil fever blister remedies near your mouth, be careful not to accidently ingest them.
