细辛在《外台秘要》汤剂中的用量研究

Research on Asarum herb dosage of herbal decoction in Waitai Miyao

文章应用文献计量分析手段,对《外台秘要》中涉及细辛的汤剂进行整理,总结共97首汤剂中使用细辛,对其不同剂量频次分类整理,得出细辛的日常用剂量为13.8g、27.6g和41.4g,剂量范围在6.9～69g,明显高于《中国药典》对细辛用量范围的规定。文章分析《外台秘要》汤剂中应用细辛剂量明显大于《中国药典》的规定,原因是唐代以前医家认为细辛无毒,并且唐代以前单味中药用量普遍大于现代用量规定;应用细辛的剂量范围较广,可能与《外台秘要》不同医家的中药用量经验有关。本研究为细辛用量研究提供文献学的依据,为《中国药典》及《中药学》教材中细辛剂量的标准设定提供参考。
