10 Natural Treatments for Cold Sores

Oral herpes, also known as cold sores or fever blisters, is caused by a virus that is generally passed from one person to another by kissing or close contact with someone who has an active breakout, or by using contaminated objects such as shaving razors, lipsticks and towels, among others.

Cold sores appear as red blisters or breakouts on the lips. Before these blisters become visible, the person may feel an itching or burning sensation, which are signs that a breakout is on its way.

According to specialized studies, by the time we reach adulthood, almost everyone has had a cold sore at a certain point. And since this condition is so common, there are lots of different treatments that could help you treat or even cure it.

How can I naturally treat and cure cold sores?

We usually realize we have oral herpes when we wake up and see we have a cold sore. When this happens, there are a number of things you can do to help alleviate this lesion and make it less bothersome for you.

Before implementing any kind of natural treatment, we recommend cleaning the affected area with antibacterial soap and water to keep the virus from spreading any further.

Garlic treatment

Chopping garlic

Garlic is a natural antiviral element that’s ideal for fighting off cold sores. All you have to do is cut a clove of garlic in half and rub it on the blister for a few seconds.

Milk treatment

Milk is rich in lysine, a component which helps to inhibit arginine, the amino acid responsible for causing oral herpes breakouts. Therefore, you can speed up the curing process with this milk treatment. Just dip a cotton ball in a bit of milk and rub it on the cold sore.

Ice treatment


As soon as you start to feel any itching or swelling around your lips, we recommend applying a bag of ice wrapped in a towel to the area for a few minutes.

Black tea treatment

To alleviate the pain associated with cold sores and speed up the curing process, you can apply a black tea compress to the affected area.

Tomato and aloe vera treatment

Insides of aloe

Clean the affected area daily and then apply a bit of tomato pulp. Allow it to set for a minute and then apply some aloe vera. This will help the blister to dry out.

Lemon juice treatment

Lemons are natural disinfectants and antiseptics, meaning they are great for fighting off viruses like oral herpes, which causes cold sores. For this treatment, just apply 4 drops of lemon juice to the blister 3 times per day.

Yogurt treatment


Yogurt contains a substance that naturally eliminates the herpes virus and cleans the affected area. We recommend eating yogurt during the entire time that you are suffering from this condition, as well as applying it directly to the blister. If you choose to apply it directly, the yogurt should be nice and cold.

Green tomato treatment

Mix green tomato pulp with a tablespoon of baking soda. Then, apply this mixture to the affected area with a cotton ball.

Honey treatment


Mix one teaspoon of pure honey with a bit of vinegar. Apply the mixture to the affected area 3 or 4 times per day.

Salt treatment

Use a spoon to crush salt until it becomes very fine. Then, apply it to the affected area with a cotton ball; repeat this process 2 to 3 times per day.

Recommendations for even better results

In addition to treating cold sores naturally, you should keep in mind that there are certain hygiene habits that can help you get rid of the virus altogether and thus avoid having to deal with this condition in the future.

  • If you want cold sores to dry out quickly, you should clean them every day.
  • Avoid exposing them to direct sunlight.
  • Do not pop the blister or remove the dead skin once it has dried out. This will go away on its own once the virus is gone.
  • Once you have finished your treatment, throw away any products or elements that were in contact with the wound, such as toothbrushes, razors and makeup products, among others.
  • Stop consuming all foods with arginine. This amino acid is crucial to the herpes virus’s metabolism and will allow the virus to live longer in your body. Some foods with very high levels of arginine include chocolate, cola drinks, peas, peanuts, gelatin, walnuts and beer.
