薄荷始载于《唐新修本草》本品原名薄荷,薄荷为其音讹,故名。薄荷为唇形科植物薄荷{Mentha leplocalyx Bxiq }的地上部分,是我国常用的传统中药之一,又是世界三大香料之一,号称“亚洲之香”,广泛应用于医药、化工、食品等领域,世界年消费量在万吨以上,且以每年5%~10%的速度增长。我国主要产地有江苏、江西、河北、四川等省。其药用价值是以薄荷全草入药,亦可食用,主要用来提炼薄荷油和薄荷脑,二者是薄荷发挥作用的主要成分,也是区分不同薄荷品种的依据。薄荷可用与牙膏于口腔卫生用品、食品、卷烟、酒、清凉饮料、化妆品与香皂的加香。在医药上,它广泛应用于祛风、防腐、消炎、镇痛止痒等药品中,如清凉油、风湿油等。
《本草纲目》认为:薄荷味辛、性凉、无毒。长期做采生吃或熟食,能祛邪毒,除劳气,解困乏,使人口气香洁。还可以治痰多及各种伤风。此外,煎汤洗可治脚疮,榨汁服可去风热及口齿诸病,捣成汁含服去舌苔苦涩;用叶塞鼻,止出血;还可以蜂蛰蛇伤。薄荷有疏散风热、清头目、利咽、透疹、疏肝解郁的功效,用于治疗风热感冒及温热初起、麻疹不透或风疹
