Home Remedies for Cold Sores

1. Ice

Ice helps reduce the swelling, redness, and pain caused by a cold sore.

• Wrap an ice cube in a clean washcloth.
• Place it over your cold sore for 10 to 15 minutes.
• Repeat this every three to four hours.

2. Garlic

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.
• Repeat the process three to five times a day.

Warning: You may feel a burning sensation when applying raw garlic on the blister-like lesions.
