描述
Docosanol is a saturated 22-carbon aliphatic alcohol which exhibits antiviral activity against many lipid enveloped viruses including herpes simplex virus (HSV). Docosanol speeds the healing of cold sores and fever blisters on the face or lips. It also relieves the accompanying symptoms, including tingling, pain, burning, and itching. Docosanol cannot, however, prevent cold sores or fever blisters from appearing. Docosan-1-ol is found in ginkgo nuts and potato.
