What Are Cold Sores?

Do you call them fever blisters or cold sores? Most people know these bright red sores by one of these two names. They are painful spots that usually burn or itch without medication or an over-the-counter treatment. In the end, the tiny blisters eventually pop and begin to form a crusty layer on the surface.

They commonly develop on the edges of the lip, but they might also be seen on the chin, cheeks, or around the nose.

A fever blister is actually caused by the herpes virus type one. You may have this virus in your body without even knowing it until it is awakened and presents itself in the form of a cold sore.

An outbreak is easily triggered by stress, sunburn, fever, or cold. You should keep in mind that sores are highly contagious when in this stage. It can be spread to other parts of the body if you inadvertently touch it and then rub the eyes, scratch your arm, or touch another person.

These cold sores can’t actually be cured with any type of treatment. You may be able to take away some of the more troublesome symptoms that cause discomfort, though. This is where the all-natural approach of using castor oil for fever blisters comes in.

How Does Castor Oil Help with Cold Sores?


While there is no known cure for the herpes virus that causes cold sores, you can use castor oil for fever blisters with successful outcomes. The ricinoleic acid in castor oil has great anti-viral and antibacterial properties. This means that it can help the virus to return to a dormant state and kill any bacteria that might be worsening your sore.

The second reason that it’s ideal to use castor oil for cold sores is to moisturize and comfort the sore skin. It can naturally restore moisture and help to generate the growth of new skin as the blister heals. This allows you to move on from this embarrassing outbreak rather quickly.

How to Use Castor Oil for Cold Sores?

Castor oil, known for its anti-inflammatory and antimicrobial properties, can potentially help with cold sores if applied in the correct way:

  • Clean the Area: Before applying anything to a cold sore, you should first clean the area with mild soap and warm water. This will help remove any dirt or other irritants that could further inflame the sore.
  • Apply the Oil: Once the area is clean, apply a small amount of castor oil directly to the cold sore. You can use a cotton swab or your fingertip, but make sure your hands are clean before applying.
  • Leave it On: Allow the oil to soak into the skin rather than washing it off. It might be most convenient to do this before bed so that the oil can stay on overnight.
  • Repeat: Reapply the oil a few times a day until the cold sore has completely healed.
