Cold sores

Cold sores are caused by the Herpes simplex virus, which is transmitted by contact such as kissing an infected person or sharing eating utensils.

The virus may lie dormant in the body for years, sometimes without causing any symptoms, only to be activated during periods of low immune status, stress, exposure to cold, and sunburn. Some women also find that menstruation can trigger cold sores.

• The amino acid L-lysine helps to reduce the frequency and severity of cold sore outbreaks
• Zinc, Echinacea and Vitamin C help to keep the immune system strong, and help to fight the Herpes virus

The Herpes virus is made stronger by the amino acid L-arginine and weaker by L-lysine. Avoid foods rich in L-arginine (such as nuts, chocolate, carob, coconut, soya beans and oats). At the same time, increase foods high in L-lysine, (such as kidney beans, split peas, fish, lamb, milk, cheese and sprouts), and consider taking an L-lysine supplement.

Stress can be a trigger for cold sore outbreak - if you are getting lots of cold sores your stress levels may be to blame - look for ways to cope better.

Consult your healthcare professional if:

• Cold sores develop near the eyes or on eyes
• You develop a high fever or chills
• Your sores are very painful
