中药剂量单位"分"的考证研究OA

The verification of dosage is an important component of contemporary classic formula research,and to accurately convert the dosage of ancient formulas,a clear understanding of ancient measurement scales is required.This article reviews the evolution process of the unofficial unit of measurement commonly used in ancient Chinese medicine,'fen'.It is believed that during the Han and Tang dynasties,'fen'was a unit under the'Liang-Fen-Zhu'system,which was used according to the standard of 4 Fen equal to 1 Liang.During the Song,Jin,and Yuan dynasties,there was a process of transition from the'Liang-Fen-Zhu'system,where the 4 Fen combined with 1 Liang,to the'Liang-Qian-Fen'system,where the 10 Fen equal to 1 Qian.During the Ming and Qing dynasties,the'Liang-Qian-Fen'system was adopted,which could be converted according to the standard of 1 Qian for every 10 Fen;However,some medical books directly copied the dosage of previous prescriptions without making any changes,so it is necessary to pay special attention to the source of these prescriptions and analyze them separately for specific doctors and medical books.If it is clear that they come from the Han,Tang,and Song dynasties,they should still be converted and used according to the old system of 4 Fen in 1 Liang,and cannot be generalized simplistically.
