杜仲(Eucommia ulmoides Oliv.)是杜仲科植物,为我国特产。《本草纲目》载:“皮可治肾虚腰痛、风冷伤肾、频惯堕胎”。我国古代医家很早即用于治疗类似近代高血压症状的疾病。由于杜仲效果确实,使用量大,而又是剥皮使用,生长期长,长期以来药源不足,供不应求。因此寻找其代用品,对国民经济和人民健康都有重大意义。杜仲树每年生长大量树叶,均任其枯黄萎落,弃而不用。杜仲叶是否具有与皮相同的成分和功用,值得研究。我们进行了下列实验,现报告于下。一、实验与结果1.样品所用样品均由南川药物种植场王桂英等供给。(1)杜仲皮水煎出物:简称皮水。原生药
Eucommia ulmoides Oliv. is a plant of the Eucommia family and is a specialty of our country. “Compendium of Materia Medica” contains: “Pi Kezhi kidney deficiency back pain, wind-chilled kidney, frequent abortion ”. Ancient Chinese medical doctors used to treat diseases like the symptoms of modern hypertension very early. Due to the fact that the effect of Eucommia is indeed high and its use is large, it is also used for stripping and has a long growing period. Since the source of medicine has been insufficient for a long period of time, the demand exceeds supply. Therefore, finding substitutes for them has great significance for the national economy and people’s health. Eucommia tree grows a lot of leaves each year, all let its yellow withering, abandoned without use. It is worth studying whether Eucommia ulmoides leaves has the same composition and function as skin. We conducted the following experiments, which are reported below. I. Experiments and results 1. Samples used by the sample were all supplied by Wang Guiying, a Nanchuan drug plantation. (1) Decoction of eucommia ulmoides water: Abbreviation dermal water. Native drug
