How to Get Rid of a Cold Sore

Herpes simplex virus (HSV) is one of the most common causes of viral infections in people. HSV-1 is the most common cause of cold sores. As many as 90% of Americans have been exposed to HSV-1 because it is highly contagious and easily transmitted in saliva when kissing, or sharing items like straws, forks or toothbrushes.

Some people are more prone to cold sores than others. Some people, though exposed to the virus, have never had a sore, or had only a few outbreaks during childhood. Others have ongoing episodes of cold sores throughout their lives.

This is because once you have been exposed to the virus it will stay stagnant in your body. When the immune system is weakened by infections, during menses or times of stress, the virus reactivates and causes an outbreak. While most infections are mild and resolve spontaneously within a week, infants and people with a very weak immune system (i.e. HIV or cancer patients) can suffer serious complications from HSV-1 infections.

They’re unsightly and painful, but fortunately, there are a few things you can do to treat them. Read on to learn how to get rid of a cold sore and keep it from coming back.

1. Don’t Touch!

First and foremost, if you have an outbreak avoid touching the blisters to prevent them from spreading around your mouth or to other parts of your body.

2. Lysine

Lysine is a natural supplement that can decrease the frequency of cold sore outbreaks and speed up the healing process. Avoid taking high doses of lysine for a long time, and take the supplement cautiously if you have high cholesterol levels or heart disease. You can safely increase the amount of lysine in your diet by adding more lysine-rich foods like fish, chicken, and eggs.

3. Zinc

Zinc is a mineral with potent antioxidant qualities, thus boosting the immune system. Studies have found that zinc can fight both HSV-1 and HSV-2, and applying zinc oxide on sores can help speed up recovery time.

4. Propolis

Propolis is a natural resin made by bees that contains plenty of antioxidants. Some research studies indicate that propolis can inhibit the replication of HSV-1 and HSV-2, reduce the symptoms and pain in affected areas, and may have comparable effects with the prescription ointment Zovirax. Use propolis cautiously if you suffer from allergies and asthma to avoid allergic reactions.

10. Be Careful Who You Kiss

To prevent getting a cold sore, avoid kissing a person who has a visible cold sore. You could still get infected with HSV from kissing a person without visible sores who carry the virus, but the risk is much lower.

11. Don’t Share Personal Items

Don’t share items like toothbrushes and razors, as this is a good way to spread the virus. It also pays to wash your hands as much as possible, especially after using public washrooms, airports, buses, ATMs, etc.

12. Be Sun Smart

Exposure to the sun is a well-known trigger for cold sores, and so you may want to limit your exposure to the sun and use sunscreen. Remember that your skin makes vitamin D when it is exposed to the sun, so if you avoid sun take vitamin D in supplement form to prevent a deficiency. Vitamin D helps keep the immune system strong and also has anti-viral effects.

Reduce and Manage Stress

13. Reduce and Manage Stress

Stress is another trigger of cold sores. Learn stress managing techniques such as deep breathing, meditation or yoga and use them regularly.


Always talk to a healthcare professional before starting to take a supplement, to learn about the benefits, as well as possible side effects and interactions with other herbs and drugs. All herbal supplements can trigger allergic reactions in susceptible individuals. Taking the right dose is important. Since natural supplements are not evaluated by FDA for efficiency or safety, you should use a supplement from a reputable brand.

Remember that cold sores develop more often when the immune system is weak. Choose a healthy lifestyle including a healthy diet, regular exercise and stress management techniques to boost your immune system.
