For the purpose of investigating weights in the era when the
Shan Han Lun was set forth, the weight and measures described in the
Ben Cao Jing Ji Zhu, written in the period slightly after the
Shan Han Lun, were studied. Some descriptions of the metrological standards are confusing in the
Ben Cao Jing Ji Zhu. We focused on the measuring container, whose volume is equal to that of the one cun square spoon (fang cun bi), shown in the dun huang version of the
Ben Cao Jing Ji Zhu. The volume of this measuring container was calculated on the assumption that the measures in this text follow those of the
Han Shu Li Li Shi, and a result of 5.07 cm
3 was obtained. The result was confirmed by using the actual measured values of the crude drugs. The result was also considered to support measurements of the volume in the
Ben Cao Jing Ji Zhu as following the
Han Shu Li Li Shi. With those results, descriptions of the density of honey and lard were examined, and the weight in the
Ben Cao Jing Ji Zhu was clarified to follow that in the
Han Shu Li Li Shi.
