息半夏是息县独有的优良中药材品种，在二千多年前《礼记、月令篇》曾有关于半夏的药用记载。在《本草纲目》等医学著作中对半夏入药的有关问题作了详细、深刻的阐述。清嘉庆四年，息州志对此已有记载，1979年版《辞海》将半夏列为息县特产。医药、医疗界对息县所产半夏极为推崇，为了将它区别于另外产品，特意在半夏二字 之 前 冠—“息”字，称为“息半夏”，以示对它的青睐。1914年3月，在 旧金山举办万国商品博览会上，息半夏因其个大、粉足、品质优良、疗效显著广受外商欢迎。近年来，随着市场经济的快速发展，息半夏远销日、韩及欧美市场，长期供不应求，国内各大药市常年出现有价无药的局面。息半夏以淮河、闾河沿岸出产的品质为最佳，通过大量临床试验和药理检测，9克息半夏相当于外地半夏15 克药效。多年来，息半夏以质量地道，信誉卓著而驰名中外，在同类药材中被视为珍品。据 《五十二病方》、《局方》、《仁斋直指方》和《金匮要略》等记载，息半夏入药能够治疗咳痰喘急、肺胃虚寒、呕吐眩悸、便秘泄泻、小儿惊风等症，药物实验有镇咳、止吐解毒等功效，外敷可止痛消肿。
