Causes Of A Cold Sore: What Are Its Symptoms And Natural Remedies

Cold sores are characterized by small blisters that are observed around the lips, nose or the mouth. These blisters are painful and may last for a few days. Cold sores are caused due to a viral infection and are associated with a higher chance of recurrence compared to the other viral infections.

Fortunately cold sores can be treated naturally with home remedies. This article provides information about how to treat the symptoms of cold sore naturally and at home.

Cold sores are caused by Herpes Simplex virus. There are two variants of this virus and cold sores are formed due to HSV type I.

The virus is highly contagious. During its active phase, the virus results in the formation of cold sores or blisters on the face. Eventually the sores dry and become crusted.

The virus now moves through the nerve cell to a location called the ganglion (i.e. a collection of nerve fibers) and lies there dormant for several months. The virus may get reactivated from its dormant phase, due to sudden fall in natural immunity, and may again travel to the nerve end and cause blisters.

What Are The Causes Of Cold Sores?

Cold sores are caused due to HSV type 1. The condition is highly contagious and spreads from one person to another through skin contact. Also it is suggested that kissing can lead to the transmission of this virus which causes cold sores, since the virus can multiply in infected saliva.

While it is believed that the virus can spread through contaminated surfaces or towels, this is rarely possible since herpes virus can’t survive in the environment. While there is little information about how the infection happens there are some predisposing factors,

  • Frequent fever, flu or cold infections are associated with higher risk of cold sores.
  • Exposure to the sun or ultraviolet radiation is also linked with cold sores.
  • Stress and its impact on the immune system are important causative factors.
  • Hormonal changes.
  • Skin injury.

Cold Sores Symptoms

Some of the common signs and symptoms associated with cold sores include the following,

  • Some individuals may complain of burning or tingling numbness before the appearance of the blisters.
  • As the blisters develop the area becomes inflamed and fluid filled. This condition may last for several days and the blisters may increase in size.
  • Blisters eventually dry up and leave a scab on the skin which may remain for several days. However at this time the infection is less severe and is not as contagious as during the blister stage.

Natural Remedies For Cold Sores

There are a host of treatment options for the management of cold sores. These treatment options largely include simple home remedies and natural treatment,

  • Various experts suggest that Lysine, an essential amino acid is very beneficial in reducing the severity and frequency of cold sores. Include Lysine supplements in your diet.
  • Increase the intake of citrus and fresh fruits and include vitamin C supplements in your daily routine. Vitamin C is very important to strengthen the immunity and thereby prevent the recurrence of cold sores.
  • Local application of vitamin E oils like almond oils or avocado oil is also considered very useful. Vitamin E helps in hastening the healing process by assisting the development of collagen tissue fibers.
