论张仲景对方药的计量只能用东汉官制

Weight measurement of medicinal in ZHANG Zhong-jing's formulas being only based on official system in the Eastern Han Dynasty

通过文献考据的方法从以下几方面对仲景方中药物计量只能用东汉官制进行阐析:东汉、魏晋在官秤以外不存在其他权衡制度,医家无力在官制以外创建另外一种秤两,医家不敢另行官秤以外的任何秤两,医药计量具有高度的历史稳定性,两汉权衡标准相差不大,晋代权衡沿用东汉制度,隋唐方药计量仍用汉制,经方1两的量值即是东汉官秤1两13.8 g。

Based on literature research, it is concluded that the weight measurement of medicinal in ZHANG Zhong-jing＇ s formulas was only based on official system established in the Eastern Han Dynasty from several aspects as follows： there was no other measurement systems except the official system in the Eastern Han Dynasty and Wei and Jin Dynasties. It was incapable for medical practitioners in that period to create another measurement system. It was incapable for medical practitioners to have courage to use another measurement system different from the official system. The measurement of medicinal had powerful historical stability. There was only a little difference in the standard of measurement between the Eastern Han Dynasty and Western Han Dynasty. The official system was continue to be used in the Jin Dynasty, Sui Dynasty and Tang Dynasty. It is confirmed that one liang （两） in ZHANG Zhong-jing＇ s formulas weighed 13.8 grams of the official system in the Eastern Han Dynasty.
