为了把黄精与其易混淆品种区分开来，对其名称、原植物和功效进行了整理研究。结果表明，历代文献记载以黄精为正名，其原植物来源于黄精Polygonatum sibiricum Red.、多花黄精Polygonatum cyrtonema Hua和滇黄精Polygonatum kigianum Coll. et Hemsl.的干燥根茎，而黄精属其他植物常混为黄精用；黄精常用作补益药，但各地使用也有用作其他功效者。“,”In order to distinguish Huangjing from other herbs ,a literature study was performed on the name , botanical origin and functions. The results showed that in the ancient literature Huangjing is the normal name,and the botanical origin includes the dry rhizome of Polygonatum sibiricum Red.,Polygonatum cyrtone-ma Hua and Polygonatum kigianum Coll. et Hemsl. However ,other plants of Polygonatum are often used as Huangjing. Huangjing is usually as an herb to tonify ,but in some areas Huangjing is also used for other ef-fects.
