血竭素有“活血圣药”之称，原药系由天然分布于热带雨林中的棕榈科黄藤属（Daemonorops）的常绿攀缘植物麒麟血藤（D．draco）及该属其他物种的果实的分泌树脂萃取而成。我国商品血竭，传统上原由东南亚进口。由于热带森林面积税减，野生植物资源枯竭，血竭货源匮乏，价格昂贵 It is known as the “blood and holy medicine.” The original medicine consists of the D.draco, an evergreen climbing plant of the genus Daemonorops, which is naturally distributed in tropical rain forests, and the fruit of other species of this genus. The secretory resin is extracted. China’s commodity exhaustion has traditionally been imported from Southeast Asia. Due to the tax reduction in the tropical forest area, wild plant resources are depleted, blood supply is scarce, and prices are high
