Overview

Cold Sores, or HSV-1, are caused by the Herpes Simplex Virus, which is known to hide in the spine. During times of stress or when the immune system is compromised, the herpes virus may cause an outbreak, resulting in one or more cold sores. Cold sores cause mild discomfort to severe physical pain. While few over the counter herpes treatments work, Lysine (especially as a combination therapy) has been linked to a reduction in Cold Sore symptoms.
