一、四种药用植物的生长概况近些年来在东北的大兴安岭、小兴安岭、张广才岭、老爷岭、完达山寒冷地带开发了具有独特疗效的几种药用植物:①刺五加〔Acantho panax senticosus(Rupr.etMaxim.)Harms〕土名老虎(?)子,生长在东北次生林下,灌木,茎常被密剌,有少数较直的分枝,小叶五枚,有时三枚,叶纸质,上面有毛或无毛,幼叶下面沿脉有褐色毛,有特异香气。每年春、秋两季挖根和根状茎入药。它虽属五加类药物,但它由于所处地理位置不同其药性也异。同现在应用的“五加皮”属萝藦科植物杠柳(Periploca sepi-um Bge.)和五加科植物细柱五加(Acantho-panax gracilistylus.W.W.Smitn)的根皮不同,前者称为北五加皮(香加皮),后者称南五加皮,两者同刺五加并非同一物。②山豆根(Menispermum dauricum Development of First and Fourth Medicinal Plants In recent years, several medicinal plants with unique curative effects have been developed in the northeastern Daxinganling, Xiaoxing’anling, Zhangguangcailing, Laoyeiling and Wandashan cold regions: 1 Acantho panax Senticosus (Rupr.et Maxim.) Harms] The native name of the tiger (?), growing under the secondary forest in the Northeast, shrubs and stems often densely enclosed, with a few straight branches, five leaves, sometimes three, sometimes leaves papery , Hairy or glabrous above, with brown hairs along veins below young leaves, with a characteristic aroma. Every year in spring and autumn, roots and rhizomes are used as medicine. Although it is an additive drug, it has different drug properties due to its geographical location. In contrast to the root bark of Periploca sepi-um Bge. and Acantho-panax gracilistylus. WWSmitn, which is currently used, the former is called North Wujiapi (Shangjiapi), the latter known as South Wujiapi, are not the same thing as Acanthopanax. 2 Shan sowing root (Menispermum dauricum
