Coconut Oil for Cold Sores

Overview

Coconut oil is a potent natural ingredient that has been used for therapeutic purposes for millennia. One of its lesser-known applications is as a possible treatment for cold sores.

Coconut oil is rich in medium-chain triglycerides that exhibit antiviral, antifungal, and antibacterial activity, all of which can encourage recovery and help ward off secondary infections in lesions caused by viral agents.

It also has antiseptic qualities that may relieve discomfort. Additionally, its moisturizing nature can soothe the affected area and reduce visible symptoms.

Cold sores, often termed “fever blisters,” are small fluid-filled blisters that typically appear in clusters on or around the lips. After they rupture, a crusted scab forms. Cold sores are contagious and are caused by the very common herpes simplex virus.

How to use coconut oil for cold sores

Coconut oil can be used both topically and orally to assist in managing cold sores. For optimal results, opt for organic, unrefined coconut oil.

To use it topically, begin with a little melted coconut oil. Dab it directly onto the area with a cotton ball or cotton swab, gently massaging it into the blisters. If you touch the blisters, wash your hands right away.

You can also take coconut oil internally by consuming it plain or incorporating it into meals. Melt it into coffee, or use it as a cooking fat.

Is it effective?

Research specifically on coconut oil for cold sores is limited, but several studies show various health benefits of coconut oil and its effectiveness in certain treatments.

Coconut oil contains monolaurin and lauric acid, two compounds with notable antiviral, antimicrobial, and antibacterial effects. Research has shown these substances can be effective against certain viruses, including herpes.

Virgin coconut oil’s anti-inflammatory and pain-relieving properties may also help reduce swelling and speed healing.

Even with coconut oil treatment, cold sores need time to resolve. The initial outbreak usually lasts the longest, roughly two weeks. Later outbreaks may run about a week, although coconut oil and other remedies may shorten recovery by a few days.

Risks and side effects

Applying coconut oil topically is safe for most people. Those with sensitive skin, though, might develop irritation or acne. For that reason, test it on a small area of skin before wider use.

There are greater concerns with ingesting coconut oil. It is a fat and can cause digestive upset, particularly if you’re not accustomed to consuming it neat or in large amounts. If you choose to eat it, do so sparingly, like any fat.

Some evidence suggests that consuming coconut oil could be unfavorable for heart health because of its high saturated fat content. Therefore, limit intake to small, occasional amounts. If you’re aiming to lower cholesterol, prefer heart-healthy oils that remain liquid at room temperature.

Other remedies for cold sores

Besides prescription antivirals and over-the-counter antiviral products (both of which can work well), several other natural remedies may help reduce cold sore symptoms and aid healing.

Aloe vera gel is a notable example. Some preliminary studies indicate that pure topical aloe vera can ease discomfort from cold sores due to its anti-inflammatory and restorative effects.

Lemon balm is another natural option that may help with cold sores because of its antiviral and anti-inflammatory actions. A member of the mint family, lemon balm—or an infusion of it—can lessen swelling and redness tied to cold sores, improving their look. If sores are on your lips, use a lip balm with this ingredient to keep the lips hydrated. Aim for a product with at least 1% lemon balm and free of irritants.

You can apply these remedies topically alongside coconut oil.

Takeaway

Coconut oil’s antiviral, antiseptic, and anti-inflammatory qualities are what make it a possible option for treating cold sores. Applying it topically several times a day offers the most immediate benefit without the saturated fats associated with ingestion. It can be used together with over-the-counter antivirals or other natural treatments like aloe vera or lemon balm to promote faster recovery.
