息半夏是息縣獨有的優良中藥材品種，在二千多年前《禮記、月令篇》曾有關于半夏的藥用記載。在《本草綱目》等醫學著作中對半夏入藥的有關問題作了詳細、深刻的闡述。清嘉慶四年，息州志對此已有記載，1979年版《辭海》將半夏列為息縣特產。醫藥、醫療界對息縣所產半夏極為推崇，為了將它區別于另外產品，特意在半夏二字 之 前 冠—“息”字，稱為“息半夏”，以示對它的青睞。1914年3月，在 舊金山舉辦萬國商品博覽會上，息半夏因其個大、粉足、品質優良、療效顯著廣受外商歡迎。近年來，隨著市場經濟的快速發展，息半夏遠銷日、韓及歐美市場，長期供不應求，國內各大藥市常年出現有價無藥的局面。息半夏以淮河、閭河沿岸出產的品質為最佳，通過大量臨床試驗和藥理檢測，9克息半夏相當于外地半夏15 克藥效。多年來，息半夏以質量地道，信譽卓著而馳名中外，在同類藥材中被視為珍品。據 《五十二病方》、《局方》、《仁齋直指方》和《金匱要略》等記載，息半夏入藥能夠治療咳痰喘急、肺胃虛寒、嘔吐眩悸、便秘泄瀉、小兒驚風等癥，藥物實驗有鎮咳、止吐解毒等功效，外敷可止痛消腫。
