3. Lysine Supplements
Lysine is an amino acid that may inhibit the replication of the herpes virus. Taking lysine supplements regularly, or incorporating lysine-rich foods like dairy, fish, and chicken into your diet, can help prevent future outbreaks and possibly shorten the duration of existing cold sores.
4. Tea Tree Oil
Tea tree oil has antiviral and anti-inflammatory properties that can help reduce the severity of cold sores. Dilute tea tree oil with a carrier oil, such as coconut or olive oil, and apply it to the sore with a cotton swab. Be cautious to avoid irritation, as tea tree oil is strong.
