Methyl salicylate is an organic ester naturally produced by many species of plants, particularly wintergreens. Methyl salicylate is used for temporary relief of muscle or joint pain caused by strains, sprains, arthritis, bruising, or backaches. It is also used in aromatherapy as oil of wintergreen. In cosmetics, it is used as a warming agent and in sport massage products, as a rubefacient. Very low concentration of methyl salicylate is used as a flavoring agent in candy, chewing gum, cough drops and toothpaste.
