麻黄是一种常用中药,始载于《神农本草经》,有“发表出汗,去邪热气,止咳逆上气,除寒热”之功效。麻黄的炮制方法主要是蜜炙,据文献记载:麻黄蜜炙后,其挥发油含量减少了二分之一,而麻黄碱减少甚微:;。为进一步探讨麻黄不同炮制的(麻黄、炙麻黄、麻黄绒)对临床疗效的影响,本文以麻黄总生物碱为依据, Ephedra is a commonly used traditional Chinese medicine. It was first published in the “Shen Nong’s Materia Medica.” It has the effect of “publishing sweat, removing evil heat, relieving cough and reversing upper air, and removing cold and heat.” The processing method of ephedra is mainly candied fruit. According to the literature, after the ephedra preserve, its volatile oil content is reduced by one half, and ephedrine is reduced by a small amount. In order to further investigate the effects of different processing of ephedra (Ephedra, Ephedrae, and Ephedrae) on clinical efficacy, this article is based on the total alkaloids of Ephedra.
