Abstract: Objective: To summarize the rules of medication for constipation treated by four scholastic sects of Jin-Yuan dynasties, in order to provide documentary evidence for the clinical treatment of this disease, and to contribute to the improvement of the academic system of the four scholastic sects of Jin-Yuan dynasties.Methods: Collect the prescriptions related to constipation in the medical works of the four scholastic sects of Jin-Yuan dynasties, make statistics on the prescriptions that meet the inclusion criteria, use WPS Excel software to establish the database of prescriptions, use SPSS 20.0 statistical software to analyze the frequency, factor analysis and correlation of traditional Chinese medicine, and use IBM SPSS modeler 18.0 statistical software is used for data mining of high-frequency drugs for the treatment of constipation, and the core network diagram of high-frequency drugs is drawn with the software of cytoscpae.Results: A total of 67 prescriptions for constipation were obtained, including 111 prescriptions, with a total frequency of 571. According to the statistics, the common high-frequency drugs for constipation are tonifying qi herbs, heat-clearing herbs, purgative herbs, surface-relieving herbs, regulating qi herbs and tonifying blood herbs. According to the high-frequency drug association analysis, 38 pairs of commonly used drugs and 15 groups of commonly used drugs were excavated. According to the correlation analysis of high-frequency drugs, the core network of drugs was drawn, and four groups of commonly used clinical core groups were mined.Conclusion: The study found that the four masters of Jin-Yuan dynasties believed that constipation was closely related to spleen, large intestine and stomach.
