Cold sores, otherwise known as fever blisters, are the result of the herpes virus, known as herpes simplex. Cold sores usually show up on or around the lips, and can even show up on the nose or face. The ailment is painful and unsightly—and is highly contagious. The virus lives in the body and manifests itself only when we are under stress and have a lowered immune system. Fighting the herpes virus needs to be approached from the inside, although external application will help the area heal after the virus has been fought.
Prevention is the best remedy for this ailment. Many factors can trigger cold sores, including an imbalance of amino acids or a lack of l-lysine (an essential amino acid provided in foods), too much stress, and overexposure to sun. To protect yourself, always wear a sunscreen on your face and lips when outdoors, and keep it on continuously. Some trigger foods that can cause an outbreak include almonds, peanuts, citrus fruits, and chocolate. Also keep your immune system up by getting rest. If cold sores are reoccurring, find out why your immune system is so low, and deal with that problem.
