What’s A Cold Sore

Cold sores are nothing but contagious oral ulcers caused by the herpes simplex virus. Shilpi Agarwal, board-certified family medicine and integrative and holistic medicine physician in Washington, D.C, explains that the virus is mostly transmitted by close contact with skin or saliva.

Quite similar to the chickenpox virus, the HSV virus lives in nerves with branches to the skin. 

There are two broad strains of HSV:

HSV 1 infects the mucous membranes near the mouth, lips, nose, and face, while HSV 2 infects near the genital organs. 

Causes Of Cold Sores

The cold sores can be transmitted amongst family members or to partners through kissing, sharing personal items, food, or via oral sex. 

After the initial flare-up, the virus reaches a collection of nerve cells called ganglion and resides in a dormant position. 

Several factors might be responsible for recurrence or trigger of cold sores; some of these are:

  • Hormonal changes due to puberty, menopause, or pregnancy
  • Fever or flu
  • Exposure to UV rays of the sun or harsh weather conditions
  • Immune system changes
  • Stress
  • Fatigue 

As per WHO, 67% of the population below the age of 50 years has HSV 1. Also, some people are more prone than others to recurrent cold sores. This includes the ones with a weakened immune system, those suffering from HIV or undergoing chemotherapy, or those who are organ recipients. 

Eczema and psoriasis also increase the risk of recurring cold sores.

Here are some of the most effective ones:

Peppermint essential oil is one such energy-boosting oil that has been found to relieve the pain and redness of cold sores. 

The aromatic tea tree essential oil also shows promising benefits of fighting against the herpes simplex virus that causes cold sores. Apart from these two, several other essential oils have also been proven to miraculously alleviate symptoms of cold sores.
