Cold sores are caused by the Herpes simplex virus, which is related to chicken pox and shingles. The virus enters the body through the skin, and remains in the body for life. Herpes simplex lies dormant for long periods of time, and becomes active during a cold or flu, stress, or hormone changes.

Symptoms can develop within a week after exposure to the virus. A tingling sensation usually occurs one or two days before the sore appears, followed by a painful red bump. A scab forms as the sore begins to heal.  Because Herpes simplex is contagious, you should cover the sore, wash your hands after touching the sore, and avoid direct contact with others during an outbreak. Natural remedies for cold sores provide antiviral, soothing properties.

Lemon balm

A member of the mint family, lemon balm (Melissa officinalis) contains antiviral compounds known as polyphenols. These compounds prevent the virus from attaching to the body’s healthy cells. Lemon balm is particularly effective against herpes viruses.

Prepare a lemon balm infusion by placing 1 ounce of dried leaves in a quart size canning jar. Fill the jar with boiling water, cover tightly, and brew the mixture at room temperature for 4 hours. Strain and drink freely throughout the day.  You can also apply the infusion or the dregs topically to the cold sore.

Kitchen remedies

Two natural remedies for cold sores may be in your refrigerator right now: ice cubes and whole milk. To relieve pain, rub the sore with an ice cube every 10 minutes for an hour. You can prepare a soothing compress by soaking a cloth in a room temperature glass of whole milk. Apply the compress to the sore for 10 minutes.

Lysine

Two amino acids-lysine and arginine-play a key role in the life of the Herpes simplex virus. Arginine promotes reproduction of the herpes virus, and lysine suppresses it.  To help your body fight the virus, avoid foods that contain high levels of arginine, such as nuts, chocolate, and cola. You can take a daily 2000 mg lysine supplement, or eat plenty of lysine rich foods, such as grapefruit, pears, apples, papaya, lentils, and soybeans. 

Echinacea

Echinacea (Echinacea spp.) stimulates the immune system and provides antiviral properties. Take 15 to 30 drops of echinacea root tincture in water 3 times a day at the first itching, tingling sign of a cold sore. A slight numbing or tingling of the tongue after taking echinacea is normal and harmless. Individuals with autoimmune illnesses, such as
