《金匮要略》黄芪用量考证及其量效关系探讨

Textual research on the dosage of Astragali Radix in Synopsis of Golden Chamber and discussion on the relationship between its dosage and effect

黄芪是现代中医临床常用的补气药,其扶正祛邪之效最早可追溯至汉代。文章通过对《金匮要略》吴迁本与邓珍本方剂中黄芪用量的文献考证,提出其量效关系:在《金匮要略》7首含有黄芪的方剂中共有两种用量。用量为三两时主治无形邪气,主要发挥入里补虚、助阳开郁的功效;用量为五两时主治有形实邪,主要发挥走表驱邪、温阳实卫的功效。提示应充分重视《金匮要略》吴迁本的研究与使用;对于经方用量,应充分利用版本、他书异文等做好文献考证,为中医临床提供指导。
