Most people have heard of cold sores, but might not know exactly what they are. Cold sores are small, fluid-filled blisters that usually appear on the lips or around the mouth. While they can be irritating and embarrassing, they typically go away without any treatment within a few weeks.

However, there are some things you can do to speed up the healing process and get relief from the symptoms. One natural remedy is using essential oils for cold sores! Essential oils have many properties that can help to heal wounds and soothe inflammation.

In this post, we will discuss what cold sores are and how to use essential oils for cold sores relief. We will also provide a few recipes for blends that you can easily make at home!


What are Cold Sores?

Also known as fever blisters, cold sores are fluid-filled red blisters that appear in patches and form around the mouth (most common), nose, or any other part of an individual’s face. Although rare, these blisters may also appear on your fingers. Cold sores are spread by the Herpes Simplex Virus (HSV-1).

These contagious blisters are spread from one person to another through physical contact. Kissing has been shown to be the most common method through which cold sores are spread. Oral sex, though rarely, also provides another route of transmission.

Typically cold sores heal on their own within 2 to 3 weeks.

Symptoms include:

  • sore throat
  • muscle aches
  • fever
  • headache
  • painful gums
  • swollen lymph nodes

There is no definitive medication for treating cold sores. Recurrence and drug resistance are some of the challenges facing both patients and doctors when it comes to the treatment of these itchy, painful, and scab-forming blisters.

This has led to extensive research on alternative methods of managing fever blisters and associated symptoms. One promising therapeutic alternative is the use of safe essential oils.

What causes cold sores?

Below are some of the most common causes of cold sores!

Viruses of the Herpesviridae family

Both Herpes Simplex Virus (HSV) type 1 and type 2 belong to the Herpesviridae family. These 2 viruses are the specific microorganisms for cold sores in humans. It was initially believed that HSV-1 only caused oral sores, but according to the WHO it can also cause genital herpes.


After an infection with HSV and subsequent healing, these viruses remain dormant in one’s body until they are triggered to recur.

Hormonal changes, trauma or injury to the skin, long periods of exposure to sun and wind, bouts of stress, fever, other viral infections, and changes in one’s immune system are some of the factors known to cause a cold sore to reappear in a previously infected person.

Applying any of the above-mentioned essential oils directly on your skin is one of the easiest and most effective ways of managing cold sores and associated symptoms. Always dilute essential oils with a carrier oil before applying to the skin. Below are recipes to apply topically to your skin!

Consider inhaling your preferred essential oil for cold sores by using an oil diffuser. Strategically place your diffuser in a convenient spot. That is in a spot where the oil vapors will still reach you in concentrated amounts and where the risk of knocking the diffuser down is lowered.

I recommend you place it in the middle of the room.
