Abstract
Abstract Multiple daily applications of a topical composition having as the active ingredients an anesthetic and a surfactant with anti-vital activity decrease the time of healing of herpes simplex viral lesions from approximately seven to ten days to five to six days, as well as decrease inflammation and pain. The composition is applied to the lesions daily, approximately every four hours, preferably beginning at the prodromal stage of infection. Relief is almost immediate, and is characterized by decreased pain, swelling, and more rapid healing as compared with the untreated lesion.
