Top 10 Best Essential Oils for Cold Sores

Table of Contents (Show/Hide)

Cold sores are painful, irritating, ugly-looking and embarrassing. Some of us get them from time to time, while others suffer from them more often.

The sad truth is once you contract the herpes virus that causes them, it stays in your body for the rest of your life. There is no cure for it and it causes cold sore outbursts when certain risk factors kick in, such as a change in hormones, weakened immune system, stress, and over exposure to the sun.

Fortunately, there are treatments that can relieve you from pain and make you feel like your old self again – by speeding up the healing process.

What are Cold Sores?

Cold sores are red blisters filled with clear fluid, usually forming near the mouth or on other parts of your face. They often clump in patches – painful and tender to the touch.

Cold sores are caused by the herpes simplex virus, which usually finds its way inside your body through a break in the skin, around or inside the mouth. It is estimated that around 90% of adults worldwide test positive for this type of virus, as the virus is highly contagious.

Namely, it spreads when a person comes in contact with a cold sore or the infected fluid. People are contagious even when the cold sores are no longer visible. Once you contract the virus, you will never get rid of it and it may reactivate, causing cold sore outbursts.

When your immune system is weakened because of the infection, fever or cold, or when you over-expose your skin to the sun, or when you are under a lot of stress or go through hormonal changes, that is when you are at the highest risk of developing a cold sore once again.

Before the cold sore appears, that spot will usually give out a tingling, burning or itching sensation, 6 to 48 hours before the blistering occurs. You may also experience high fever, sore throat or swollen glands. The blisters will then break open and the fluid will ooze out, forming a crust.

Cold sores usually start to heal on their own after a few days and disappear completely within 2 weeks’ time.

Treating Cold Sores with Essential Oils

Various treatments for cold sores can speed up the healing process and help with the painful blisters and other uncomfortable symptoms. Treatments often include skin creams, ointments, and in some cases pills.

The alternative is to treat your cold sores with natural essential oils, as they can help ease the discomfort and pain, reduce swelling, and speed up the healing process.

Make sure to browse through the properties of each individual plant and its essential oil before you apply it on your skin.

It’s possible to be allergic to some of the compounds contained in the essential oils, so be careful and apply only a small amount of it to your skin for the first time in order to spot a possible reaction. If you develop a rash, swelling, or any irritation, stop using the essential oil immediately and consult a healthcare professional.

Plant Oils That Treat Cold Sores

  • Aloe Vera

    You are able to buy Aloe Vera essential oil or use creams, lip balms, or juice made out of it. However, the gel you get when you snip off the pieces of your homegrown Aloe Vera plant is also very efficient when applied directly to the cold sore.

    Aloe Vera is known to speed up the healing process, and stop the pain and inflammation. Moreover, it stimulates the growth of new, healthy skin, thanks to the glycoproteins and polysaccharides found in it. It is also rich in amino acids and contains vitamins B1, B2, B6 and C.

  • Lemon Balm Essential Oil

    This essential oil can help you heal faster and reduces the redness and swelling around the cold sores. Some studies even show that it has the potential to reduce the chance of cold sores appearing again after some time.

  • Tea Tree Oil

    Tea tree oil is known for its anti-inflammatory properties and it is proven effective against certain strains of the herpes virus.

    Never swallow tea tree oil, and test with small amount first as it is known to sometimes cause allergic reactions. Tea tree oil can be gotten in the form of gel or mixed with carrier oil.

Application

Essential oils can be used in various ways to treat cold sores. For instance, you are able to apply them directly on the infected spot, mix them with carrier oils, buy a commercial product containing them, or brew a tea to treat the affected area. Here are a few ways to use essential oils to treat cold sores.

  • Brewed Herbs

    Brewing herbs is a great way for extracting the essential oils from them. Boil a cup of water and add 2 to 4 teaspoons of crushed herbs. Let the mixture boil for another 10 to 15 minutes.

    When it cools down, strain out the plant matter and apply the tea with cotton balls on your cold sore several times a day. Never drink essential oils.

  • As a Lip Balm

    Use a cotton swab to apply a lip balm that contains essential oils to avoid spreading cold sores all over your lips and face. Avoid sharing your lip balm with anyone as this can spread the virus – even if your cold sores are healed.

  • Ointment Form

    It is possible to apply essential oils to cold sores in ointment form. In your local store, you can find ointments and creams that contain peppermint oil, lemon balm and others.

    How often you use the ointment depends on how concentrated the essential oil is.

  • Mix with a Carrier Oil

    carrier oils help carry the essential oil into the deeper parts of your skin. Usually, the mix should contain 3-6 drops of essential oil for an ounce of carrier oil.

    One of the best choices for carrier oil is coconut oil, since it contains a lot of oleic acid. This is a fatty acid which is one of the ingredients that help other elements in the mix penetrate the skin.

Potential Risks

Although essential oils are natural remedies and are usually beneficial, they need to be used properly. Here are a few things to pay attention to when applying them in your treatment.

  • Usage with Other Medications

    Firstly, to be on the safe side, if you are using any medication for a chronic condition, look up whether it’s safe to use essential oils alongside it.

    Essential oils can sometimes interfere with the effects of diabetes medicines, sedatives, thyroid issues medication, blood pressure regulation drugs and HIV therapy.

  • Don’t Overdo It

    Although they can be useful in small amounts, essential oils can become harmful if overused. Pay attention to how much and how often you apply them. Excessive amounts can weaken your epidermis, which leads to difficulties in your skin’s ability to self-repair.

  • Negative Reactions

    Your skin is unique and reactions to essential oils can be different for everyone. Pay attention to the way your skin responds to essential oils and in case there is any, even the slightest negative reaction, discontinue the treatment.

    Negative reactions can vary from rashes to irritation and burning. This might mean you are allergic or you are applying too strong of a dilution. If you develop a negative reaction, stop using the oil and consult a professional.

  • Diluted Oils are Safer

    When using essential oils in their pure form, be aware of their strength. If applying to skin, make sure you’ve diluted them with a neutral and non-abrasive carrier oil.

    This will prevent any worsening of your inflammation and will make the essential oil actually work for and not against you. Only a few essential oils, such as aloe vera oil, are mild enough for usage without prior diluting.

Safety Measures

Consult Your Doctor

If you plan to use essential oils as your only cold sore treatment, or if you plan to combine it with other medicines, you should consult your doctor beforehand.

If you start using essential oils and have an adverse reaction, or the cold sores persist and don’t respond to treatment, you should consult your doctor.

Another important thing for chronic patients is the potential interference between their chronic condition medications and essential oils. Consult your doctor before using essential oils if you are already using other medications.

Be Cautious When Pregnant

The most sensitive period of a pregnancy is the first trimester. Please do your research about using essential oils when pregnant, and consult your doctor before using essential oils.

Be Cautious When Using on Kids

Before including any essential oils in treatment for kids, consult your doctor about potential usage and dosage. As kids are much smaller than adults, we need to take special attention when it comes to dosing essential oils for them.

Generally, the dilution strength should be 1%, meaning that 1 teaspoon of carrier oil is used for 1 drop of essential oil.

Children should not use peppermint oil for treating cold sores.

Never Use on Open Sores

Essential oils should not be used on open sores since there is a high risk of irritation. Even aloe vera, which is one of the mildest of oils, may cause a negative reaction if applied on any type of open wound.
