What are cold sores and what causes them?

Cold sores, also known as fever blisters, are red, fluid-filled blisters that form around your lips, normally caused by the herpes simplex virus (HSV).

Cold sore blisters are often found clumped together in patches. At points, these blisters break leaving a scab that can last for several days.

While they can persist for three weeks or longer, cold sores usually heal completely in two to three weeks and don’t tend to leave scars.

While cold sores usually form close to the mouth, they can occur on other areas of the face and in rare cases, may even appear on the fingers, nose, or inside the mouth.

A common tell-tale sign that you’re developing a cold sore is when you experience a tingling, itching, or burning feeling around your mouth.

Cold sores are contagious and can spread the herpes virus through contact such as kissing or sharing beverages from the same vessel.

They’re usually contagious from the moment you first feel tingling or other signs of a cold sore coming on up until the sore has completely healed and disappeared. This means that cold sores can be contagious even when they’re not visible.

At present, there’s no cure for cold sores, and those who suffer from them will often experience breakouts multiple times in their lifetime. Saying this, there are certain treatments that can relieve and manage outbreaks.

While there are many over the counter and prescription treatments,

How can essential oils help with cold sores?

Whenever you peel an orange, pluck a stalk of lavender, strip a sprig of rosemary, or sniff a rose, the lovely fragrance that fills your nose is the essential oil of the plant.

Essential oils are liquids containing the natural fragrant essence extracted from flowers, leaves, bark, roots, fruit peel, berries, and other natural sources.

But how can these plant liquids help with cold sores?

Essential oils can help with many aspects of cold sores. This includes helping to reduce inflammation, offering anti-viral protection, promoting healing of the skin, preventing scarring, relieving itchiness, reducing pain, tightness, and preventing infection.

As will be explained in the next section, each essential oil has different properties and will help with cold sores in different ways and to different degrees.

How To Use Essential Oils For Cold Sores Safely:

To use essential oils for cold sores, simply dilute around 4 drops in 1 ounce of your chosen carrier oil (we recommend jojoba, sweet almond, or coconut oil) then dab it on the affected area using a clean cotton ball.

Make sure to always wash your hands before and after treating your cold sores to avoid infection and prevent spreading the virus.

The production of essential oils is not monitored by the Food and Drug Administration (FDA), so it’s important to do some research on the brands you use so you know they are high-quality and safe.

Essential oils are highly concentrated plant oils, meaning many are toxic if ingested or applied to the skin when undiluted. (Hence why they make good bug repellents!) For this reason, it’s crucial to dilute your essential oils in a neutral carrier oil before applying them to the skin.

Finally, if you have any adverse reactions, stop use immediately and consult a doctor if the issue persists.
