Cold sores are painful, fluid-filled blisters that appear on the lip, mouth or throat. They typically are caused by the herpes simplex type 1 virus, and it’s estimated that 90 percent of adults older than 40 carry it.
Outbreaks often begin with a tingling sensation around the mouth and blisters can last between seven and 10 days. The amino acid lysine has been known to heal cold sores, so eating foods rich in this substance is important during an outbreak.
Try these natural remedies for cold sores:
- Honey: Researchers at Dubai Specialized Medical Center found that topical honey application is safe and effective for treating cold sores.
- Lemon balm: The essential oils in lemon balm might inhibit the virus.
- Yogurt: Acidophilus bacteria found in certain yogurt has been shown to hinder the virus’ growth.
- Apples: High in lysine, an apple a day keeps cold sores away.
