Abstract:
To gain an in-depth understanding of the clinical application of Rehmanniae Radix during the Qing Dynasty and to clarify its specifications and corresponding therapeutic effects， this study took Rehmanniae Radix in the prescriptions documented in Research on Medical Cases of the Qing Imperial Court as the research subject. According to historical medical literature， a comprehensive investigation was conducted on the specifications， therapeutic efficacy， frequency of use， dosage， and seasonal patterns of Rehmanniae Radix employed by imperial physicians. The findings revealed that Rehmanniae Radix in the medical cases of the Qing court was primarily classified into three categories： Xiaoshengdi， Zhongshengdi， and Dashengdi. Xiaoshengdi was also referred to as Xishengdi or Cishengdi， all denoting dried Rehmanniae Radix. The term Xishengdi was inconsistently defined in the literature. It should refer to the slender variant of dried Rehmanniae Radix and was utilized as a specific specification in the medical cases of the Qing court. In contrast， the wild fresh roots of Rehmanniae Radix， described as "as slender as fingers"， were commonly documented as fresh Rehmanniae Radix in these medical cases. There were variations in Rehmanniae Radix size and grading between historical and contemporary standards. Furthermore， therapeutic differences were observed among Rehmanniae Radix specifications in the medical cases of the Qing court. Xiaoshengdi and Zhongshengdi exhibited slightly stronger blood-cooling and heat-clearing effects while maintaining a non-cloying Yin-nourishing property. In contrast， Dashengdi demonstrated a greater emphasis on Yin supplementation with relatively milder heat-clearing activity. In the medical cases of the Qing court， the dosage of Rehmanniae Radix in different specifications was usually 11.2-18.7 g per dose， typically administered twice daily. Rehmanniae Radix in different specifications exhibits variations in efficacy， which can provide evidence-based insights for precise clinical application.
