Cold sores? I despise them. Unfortunately, I am one of the not-so-lucky people who get them. Repeatedly. Lately, it seems that I’ve been getting them more frequently—no doubt due to stress.
You see, stress happens to be my biggest trigger for the painful sores, but illness, sleep deprivation, exposure, and more can all contribute to a cold sore outbreak. Now, as soon as I feel one coming on, I turn to proven effective essential oils for an easy cold sore treatment.
Also known as fever blisters, cold sores are most frequently caused by the herpes simplex virus and are usually spread by contact or kissing. At the onset of a cold sore, the area may turn red and begin itching or tingling.
Quickly after that, a blister forms and crusts over until the sore eventually heals. Not only are they unsightly, but they can also be very painful. And on top of all that, it can take several weeks before the sore is completely healed. Ugh!
The good news is that if treated at the first sign of onset, the duration of the cold sore can be shortened or even possibly eliminated altogether. The bad news is it can be tricky to do since the onset usually happens pretty quickly

The Best Essential Oils for Cold Sores
Over-the-counter treatment options are available for cold sores, but did you know that several essential oils are considered beneficial when treating them as well [source]? Not only are essential oils a completely natural alternative to OTC remedies (which, let’s be honest, is always a plus), but they’ve been shown to be an effective alternative to boot [source].
Below, I’ve listed six of the best essential oils for cold sores, and as a bonus, I’ve included some simple cold sore treatments and a recipe for a DIY cold sore-fighting lip balm.
1. Tea Tree Essential Oil
Why It’s Great: Tea tree has potent antiviral, antibacterial, and anti-inflammatory properties, which help reduce the severity of cold sores and speed up healing. It also prevents secondary infections.
Not only does tea tree possess antiviral activities that are considered effective against herpes viruses [source], it also contains potent anti-inflammatory properties. Because of this, it is commonly used when dealing with inflamed and irritated skin, making it a great choice to consider if you’re dealing with a painful and irritated cold sore.
Cold Sore Spot Treatment:
- Mix 1 drop of tea tree oil with 1 teaspoon of coconut oil.
- Apply directly to the cold sore with a cotton swab 3–4 times daily.
Tea Tree Lip Balm:
- Melt 1 tablespoon shea butter and 1 tablespoon coconut oil.
- Stir in 2 drops of tea tree oil and pour into a small container. Let it set before use.
2. Peppermint Essential Oil
Why It’s Great: Peppermint essential oil is frequently used for cold sores. When the skin is sore and inflamed, its cooling and pain-relieving properties can provide immediate relief to the burning sensation of the blister, not to mention that it also contains potent antiviral properties.
In fact, peppermint essential oil was found to directly affect the herpes virus and may be beneficial for those dealing with recurrent outbreaks. It was also shown to be effective in treating one of the virus strains resistant to antiviral medication [source].
Cooling Peppermint Compress:
- Mix 1 drop of peppermint oil with 1 tablespoon aloe vera gel.
- Apply the mixture to the cold sore with a clean cloth for 5–10 minutes.
Peppermint Lip Serum:
- Combine 1 teaspoon jojoba oil with 1 drop peppermint oil.
- Dab a small amount onto your lips twice a day.
Caution: Do not use more than two drops of peppermint EO per lip recipe. The cooling properties of peppermint can cause a strong tingling sensation that some individuals may find uncomfortable.
3. Lemon Balm (Melissa) Essential Oil
Why It’s Great: Melissa essential oil—also known as lemon balm—is generally regarded as one of the most well-known essential oils for cold sores [source]. In fact, a study published in 2012 found that even in low concentrations, Melissa showed elevated antiviral activity and inhibited the herpes virus from binding to cells [source].
Melissa is frequently listed among aromatherapy texts as one of the best—if not THE best—essential oil for cold sores. It’s important to note that Melissa is an extremely pricey essential oil, but the good news is, only a very little bit is needed!
Lemon Balm Oil Spot Treatment:
- Dilute 1 drop lemon balm oil in 1 teaspoon sweet almond oil.
- Apply to the cold sore with a cotton swab several times daily.
Lemon Balm Protective Lip Balm:
- Melt 1 tablespoon beeswax and 1 tablespoon coconut oil.
- Add 2 drops lemon balm oil and pour into a small tin. Use as needed.
4. Eucalyptus Essential Oil
Why It’s Great: Eucalyptus is another essential oil considered useful for cold sores—and much less expensive. Eucalyptus contains potent antibacterial and antiviral properties [source].
It not only benefits the cold sore but it is considered beneficial for the immune system as well. It is a potent antioxidant [source] that also contains anti-inflammatory and analgesic properties to help with pain and inflammation [source].
The cooling sensation of eucalyptus brings can also bring much needed relief to inflamed lips.
Eucalyptus Lip Ointment:
- Combine 1 teaspoon coconut oil with 1 drop eucalyptus oil.
- Apply gently to the cold sore 3 times daily.
Eucalyptus and Chamomile Compress:
- Add 1 drop eucalyptus oil and 1 drop chamomile oil to a bowl of cool water.
- Apply with a clean cloth to soothe irritation.
5. Lavender Essential Oil
Why It’s Great: Lavender makes the cut on this list due to its soothing properties. Lavender is one of the most commonly used essential oils, and for good reason—it’s beneficial for just about anything!
If your cold sore is especially inflamed and painful, lavender is an excellent choice to help relieve pain. Most commonly known for its skin-soothing properties, it is also considered beneficial when dealing with inflammation [source].
Lavender may not have the antiviral properties exhibited by some of the other essential oils on this list, but it’s definitely one of the best for inflamed and painful skin.
Lavender Honey Balm:
- Mix 1 teaspoon raw honey with 1 drop lavender oil.
- Apply to the cold sore as needed for soothing relief.
Lavender Compress:
- Add 2 drops lavender oil to a bowl of warm water.
- Soak a clean cloth in the mixture and press gently onto the sore for 5 minutes.
6. Chamomile Essential Oil
Why It's Great: Chamomile is another essential oil that has gentle, skin-soothing properties. Like lavender and tea tree, it can be used on a number of skin problems and is especially helpful when dealing with inflammation. However, that’s not all that chamomile is good for.
I tend to think of chamomile as a sort of gentle giant. It is one of the gentler essential oils, but it packs a big punch when it comes to therapeutic properties. In fact, research has shown that chamomile essential oil was active against the herpes virus without any irritating effects [source].
Chamomile Lip Mask:
- Mix 1 teaspoon raw honey and 1 teaspoon almond oil with 1 drop chamomile essential oil.
- Apply to the cold sore as needed for soothing relief.
Chamomile Healing Lip Salve
- Mix 1 teaspoon beeswax and 1 tablespoon olive oil with 3 drops chamomile oil and 3 drops tea tree essential oil.
- Melt beeswax over low heat and stir in olive oil. Add essential oils and pour into small salve container and let sit until it solidifies.
This lip balm recipe is not only moisturizing for chapped lips, but it also includes essential oils that are great for helping to keep cold sores at bay.
