Aspirin (acetylsalicylic acid) is present in many analgesic tablets. Salicylic acid is used in corn applications and in dermatologic ointments or as sodium salicylate for internal use. Methyl salicylate (oil of wintergreen) is the active ingredient in many skin liniments and ointments used for analgesic purposes. Salicylamide, salsalate (Disalcid), and sodium thiosalicylate are less toxic than aspirin and are used as weak analgesics given orally.
