Here are the top 10 home remedies for cold sores.
1. IceIce helps reduce the swelling, redness, and pain caused by a cold sore.

- Repeat this every three to four hours.
Garlic has enzymes that work as antibacterial, antiviral and antifungal agents that help treat cold sores. In addition, it acts as an anti-inflammatory and reduces swelling and inflammation.
- Cut a garlic clove into halves.
- Crush one-half and apply it on the affected area.
- Leave it on for 10 to 15 minutes.

3. Acetone Nail Polish Remover
Believe it or not, many people have actually tried this remedy and even found it effective. Acetone is believed to help dry out a cold sore.
- Dip a cotton ball in acetone nail polish remover.
- Dab it on the cold sore.

This herb prevents and treats cold sores. It has an active ingredient called glycyrrhizin with antiviral and anti-inflammatory properties.

- You can also have licorice root tea or supplements.
6. Lysine
Studies have found that taking lysine on a regular basis can help prevent cold sores due to its antiviral effects. Lysine is an essential amino acid that blocks the activity of another amino acid called arginine, which promotes replication of the herpes simplex virus.
- Take 1,000 to 1,500 mg L-Lysine supplements daily to help keep the herpes virus dormant. During an outbreak, take 1,000 mg three times a day. You can also use creams, but oral lysine is considered more effective.
- Include meat, milk, yogurt, cheese, soybeans, and other protein-rich foods in your diet as they are good sources of lysine.
Lemon balm, also known as Melissa officinalis, speeds up the healing process, soothes discomfort, and prevents the infection from spreading. It contains tannins and polyphenolic compounds that contribute to its antiviral effects.
- Steep one to two teaspoons of dried lemon balm leaves in one liter of hot water for 10 minutes. Strain and drink three to four cups of this herbal tea daily.
- Alternatively, you can apply lemon balm tea or essential oil on your cold sore three to five times a day.
Whole milk contains immunoglobulins that inhibit the virus that causes cold sores. Plus, it has a type of fat known as monocaprin with antiviral effects. Furthermore, cold milk soothes the tingling sensation and discomfort.
- Soak a cotton ball in cold, whole milk.
- Apply it on the affected area and leave it on for about 10 minutes.
- Do this once or twice a day.
9. Echinacea
Echinacea is a powerful herb that bolsters the immune system and has antiviral effects. A study by the University of Ottawa found Echinacea extract to be active against the herpes simplex virus-1.
- Dab Echinacea liquid extract on the affected area.
- You can also drink Echinacea tea, or take it in the form of tincture or capsules.
10. Tea Tree Oil
Tea tree oil has antiviral properties that can help treat cold sores and shorten the healing time.
- Dilute tea tree oil by adding three parts of water to one part of tea tree oil. Dip a cotton ball in the oil and apply it on your cold sore three times a day.
- Alternatively, you can combine tea tree oil with an equal amount of olive oil and a little eucalyptus oil. Apply it two to three times a day.
