水杨酸甲酯(Methyl salicylate)是由甲醇的羟基和水杨酸的羧基结合而生成的有机化合物,又名冬青油(由冬青树提炼)。它是一种有些许淡黄色的液体,有药草的特殊气味,味道甜甜、辣辣的,物理特性熔点-8.6℃,沸点218 ~224℃(沸腾时部分分解)。药用方面主要作为外用局部发赤剂,常用于消肿、止痛方面,但后来因为有影响血液中铁离子等相关的副作用,因此现在鲜少用于内服药物方面,主要被阿斯匹林所取代。它具有局部刺激作用,可促进局部血液循环,外用或局部涂擦可产生皮肤血管扩张、肤色发红等刺激反应,并反射性地影响相应部位的皮肤、肌肉、神经及关节,从而起到消肿、消炎和镇痛作用,亦有止痒之效。可用于扭伤、挫伤、腰痛、肌肉痛、神经痛、止痒。

Methyl salicylate (oil of wintergreen or wintergreen oil) is an organic ester naturally produced by many species of plants, particularly wintergreens. It is also synthetically produced, used as a fragrance, in foods and beverages, and in liniments.

The compound methyl salicylate was first isolated (from the plant Gaultheria procumbens) in 1843 by the French chemist Auguste André Thomas Cahours (1813–1891), who identified it as an ester of salicylic acid and methanol.
