《千金要方》开心散剂量的文献考证

Textual research on the dosage of Kai Xin San in Qian Jin Yao Fang

以《古代经典名方目录》中的"开心散"为研究对象,通过对该方在《千金要方》宋校本、新雕本中剂量差异的考证,参考两版本各自成书的特点,比对考察宋校本同一卷中其他方剂的载录方式,并以同时代的《医心方》"开心散"的记载为佐证,推论出开心散的药量应为"远志、人参各四分(一两),茯苓二两,菖蒲一两"。按照《经方本原剂量问题研究》及对方寸匕的研究结果,折算出本方的现代剂量为远志13.8 g、人参13.8 g、茯苓27.6 g、菖蒲13.8 g,再结合其散剂的服用方法,计算得知日服量为远志3 g、人参3 g、茯苓6 g、菖蒲3 g。
