Methyl salicylate
Methyl salicylate is an aromatic ester with a characteristic wintergreen odor, used in topical pain-relief products, fragrances, and flavorings.
TRPV1: A sensory ion channel activated by heat, capsaicin, and several other chemical stimuli. Methyl salicylate can activate this channel, contributing to warmth and irritation on skin.
Topical analgesic: A medicine applied to the skin to relieve pain in a localized area. Methyl salicylate is an active ingredient in some topical analgesic products.
Salicylic acid: An aromatic carboxylic acid containing neighboring hydroxyl and carboxyl groups on a benzene ring. Methyl salicylate is its methyl ester.
Menthol: A naturally occurring cyclic alcohol with a minty odor and cooling sensory effect. Menthol usually produces a cooling sensation, unlike methyl salicylate’s characteristic warming counterirritant effect.
Gaultheria procumbens: A North American evergreen commonly called eastern teaberry or American wintergreen. Its leaves contain methyl salicylate and have been used to produce wintergreen oil.
TRPA1: A sensory ion channel responsive to reactive chemicals, irritants, and environmental stimuli. This channel helps explain sensory responses to methyl salicylate and related aromatic compounds.
Wintergreen oil: An essential oil, commonly distilled from wintergreen leaves, whose principal component is methyl salicylate. The oil is a natural source of the compound and a traditional source of its wintergreen scent.
Methanol: The simplest alcohol, with the formula CH₃OH, used as a chemical feedstock and solvent. Methanol supplies the methyl group when salicylic acid is esterified.
Methyl benzoate: An aromatic ester formed from benzoic acid and methanol, used in fragrances and flavorings. It resembles methyl salicylate as an aromatic ester but lacks the neighboring hydroxyl group.
Betula lenta: A North American tree commonly called sweet birch or black birch. Its bark yields oil rich in methyl salicylate, another natural source of the wintergreen odor.
