论文部分内容阅读
本文中所举四种生药,原大都有显微镜下观察,攙雜等节,因恐对一般读者帮助不大,已从译文中删去。本品:木贼科(Equisetaceae)的植物问荆(E-quisetum arvense L)的地上干燥部分.
The four kinds of crude drugs mentioned in this article have all been observed under a microscope, and noisy sections have been removed from the translation because they have not helped the general readers. This product is the aerial dry part of Equisetum arvense L (Equisetaceae).
