Do you have a cold sore on your lip that is bothering you? If so, you are at the right place. Cold sores are common blisters that appear on or around the lips. In this article, we will tell you some home remedy for cold sores on lips and some with a prescription.

What Causes Cold Sores on Lips?

Cold sores are a symptom of Herpes simplex virus (HSV-1) type 1 infection. HSV-1 is more common and usually causes oral herpes. HSV is very contagious and can spread through direct contact with an infected person or their secretions, such as saliva, blisters or sores. You can also get HSV from sharing objects like razors, towels, utensils or lip balms.

How to Treat Cold Sores on Lips

There is no cure for HSV, but you can treat cold sores to reduce their duration and severity. The sooner you start treatment, the better. Here are some of the options you can choose from:

1. Antiviral Medications

Antiviral medications are the most effective way to treat cold sores. They work by stopping the virus from multiplying and spreading. You can get them as oral pills, creams or injections, depending on the severity of your case.

2. Over-the-Counter Creams

If you don’t have access to antiviral medications, you can try over-the-counter creams that contain docosanol. Docosanol reduces pain and itching. However, it is not as effective as antiviral medications.

3. Lemon Balm

Lemon balm is a herb with antiviral properties and helps heal cold sores faster. You can use it as tea, oil, or cream.

To make lemon balm tea, steep one teaspoon of dried lemon balm leaves in a cup of hot water for 10 minutes. Strain and drink up to four cups a day.

To use lemon balm oil or cream, apply it directly to your cold sore three to four times a day.

4. Ice

Ice can help numb the pain and inflammation caused by cold sores. It can also prevent the virus from spreading to other areas of your lip or mouth.

To use ice, wrap an ice pack or a frozen bag of peas in a cloth or paper towel and place it over your cold sore for 10 minutes at a time. Do not apply ice directly to your skin, as it may cause frostbite or damage your nerves.

5. Aloe Vera

Aloe vera is a plant that has soothing and healing properties for various skin conditions, including cold sores. To use aloe vera, cut a leaf from an aloe vera plant and squeeze out the gel. Apply it to your cold sore three times a day until it heals.

6. Sunscreen

Sun exposure can trigger or worsen cold sores, so it is important to protect your lips from the sun. Use a lip balm or cream that contains sunscreen with at least SPF 15. 

7. Stress Reduction

Stress is one of the main triggers of cold sore outbreaks, so reducing stress can help prevent or shorten them. Find what works for you and practice it regularly to lower your stress levels and boost your immune system.
