Herpes simplex virus type 1 (HSV-1) is the most common herpes simplex virus and is usually associated with cold sores. According to the National Institutes of Health, by adulthood, 30 to 90 percent of people will have antibodies to HSV-1. Campho-Phenique has become a common form of treatment for cold sores.
In 1867, Joseph Lister demonstrated that cleansing of patients' skin before and after surgery with phenol could greatly reduce infections. By 1884, Campho-Phenique Liquid was introduced as an antiseptic.
Campho-Phenique contains both camphor and phenol. Campho-Phenique works to block infections that can slow the healing process.
