10 Best Essential Oils For Cold Sores & How To Use Them

Recommended Posts


Cold sores, also known as fever blisters, are painful and also embarrassing. Some people struggle with them more than others and because they are a contagious oral virus, you can pass them back and forth between people you are close to.

The virus that causes cold sores is known as herpes simplex virus (HSV). There are two types of HSV, type l, and type ll. Cold sores are generally caused by type l. The virus can be spread by kissing or other close contact with the sores or even from contact with skin that seems normal but is shedding the virus and infected saliva without the presence of sores.

The virus is most contagious when open sores are seen and the risk is less once the blisters have dried and crusted over. You may have heard that you can catch the herpes virus from touching contaminated surfaces, washcloths or towels, know this is a myth.

Progression Of The Virus
Fever blisters go through several stages. At first, you might have tingling of your skin, followed by itching and burning around your lips. This is the first sign that a fever blister is developing (the best time to begin treatment). The blister will form on the border of the lips within 24-48 hours. It will eventually break and ooze and then dry out and crust over. A scab will form and protect the new skin underneath.

When the sores disappear, the virus enters the dormant stage where it travels up the nerve where it stays latent. When it becomes active again it travels back down the nerve to the skin and causes blisters called cold sores.

Although not usually serious, a cold sore infection can be life-threatening for those with a compromised immune system.

Some people develop antibodies and don’t get another infection again. However, 40% of adults get repeated cold sores.

Numerous studies have shown the effectiveness of essential oils to remedy cold sores. Essential oils may have an advantage over antiviral drugs that can have side effects. Keep in mind that you should not take essential oils orally. When used for the remedy of cold sores, most essential oils are applied topically to the skin after being mixed with a carrier oil such as coconut oil or sweet almond oil.

Here are ten essential oils that show promise in the treatment of the virus and ease of symptoms associated with cold sores.
