竹叶与淡竹叶之源流效用辨析.doc竹叶与淡竹叶之源流效用辨析[ 摘要] 目前临床上大多用淡竹叶代替竹叶使用, 虽然两者功效有相似之处, 但其来源和在临床应用时依然有诸多差别。本研究主要通过文献考证的方法, 对竹叶和淡竹叶的名称来源和历代本草对其性味归经和功效主治的记载进行考辨, 发现明代以前的本草中, 淡竹叶是多种竹叶中的一种, 两者并无本质区别,至《本草纲目》始收载来源与竹叶不同的淡竹叶, 并作为独立的药物被后世各家本草著作收载。因此, 为保证疗效和中药名称规范化,开展竹叶和淡竹的本草考证具有重要意义。[ 关键词] 竹叶;淡竹叶;来源;功效[ 中图分类号] R284 [ 文献标识码]A[ 文章编号] 1673-7210 ( 2016 ) 05(a) -0073-04 [Abstract] Now Lophatherum gracile can usually replace bamboo leaves in clinic. Although the two herbal medicines have similar efficacy , their sources and clinical application are still different. By making a textual research on the literature , this paper distinguishes the differences between bamboo leaves and Lophatherum gracile , including the name , the source , the flavor and meridian tropism and the efficacy recorded in Chinese materia medica works , which finds that before the Ming dynasty , in Chinese materia medica works , Lophatherum gracile isa kind of bamboo leaves , there is no essential difference between them. pendium of Materia Medica began to collect Lophatherum gracile whose source was different from bamboo leaves , Lophatherum gracile became an independent herbal drug , it was recorded in later generations materia medica works. Therefore , in order to guarantee the curative effect and the standard names of Chinese medicine , it is quite significant to carry out a textual research on the literature of bamboo leaves and Lophatherum gracile.
