清代伤寒医案267人次的舌象分析

This study was aimed to discuss common characteristics of the tongue diagnosis in typhoid medical records in the Qing dynasty. Through the reading of 46 books on typhoid medical cases with tongue diagnosis, 214 medical tongue diagnosis records with 267 tongue diagnosis mentioned were obtained. Meantime, the tongue body and tongue coating occurrence rate was counted and tongue diagnosis records in early, mid, and late Qing dynasty were analyzed. The results showed that in the 267 tongue diagnosis, tongue coating was recorded the most (91.39% ). Different stages of Qing dynasty record comparisons showed that more tongue coating texture were recorded in mid and late Qing dynasty (P < 0.01); more tongue coating color were recorded in early Qing dynasty, and less in mid Qing dynasty (P < 0.01), and increased again in late Qing dynasty; more greasy fur tongue and red color tongue were recorded in the late Qing dynasty (P < 0.01). It was concluded that the common characteristics and evolution of the typhoid tongue diagnosis were valuable in diagnosing acute infectious diseases. It may bring beneficial references for the treatment in traditional Chinese medicine.
