Objective,2,To analyze and explore the prescription rules of traditional Chinese medicine fumigation and washing to promote postoperative wound healing of perianal abscess based on data mining.,Methods,2,Literatures on the promotion of postoperative wound healing of perianal abscess by traditional Chinese medicine fumigation and washing published from January 1, 2010 to December 31, 2019 were retrieved from the databases of CNKI, WanFang Data, VIP, China Biomedical Literature Service Platform (CBM), and PubMed, etc. With the help of Microsoft Office Excel 2003, IBM SPSS Statistics 23.0 and IBM SPSS Modeler 14.1 softwares, we conduced frequency analysis, the properties, taste and meridian tropism analysis of the included traditional Chinese herbal medicines(TCHMs), cluster analysis, and association rule mining of high-frequency herbs.,Results,2,①Finally 72 articles were included, involving 72 prescriptions and 93 TCHMs, which were mostly bitter cold herbs entering the liver meridian. ②The results of frequency analysis showed that there were 6 most commonly used TCHMs (,f,>,50%), namely, Jinyinhua (,Flos Lonicerae,), Gancao (,Radix Glycyrrhizae,), Kushen (,Radix Sophorae Flavescentis,), Danggui (,Radix Angelicae Sinensis,), Huangbai (,Cortex Phellodendri,), and Pugongying (,Taraxacum officinale,). ③Cluster analysis showed that the included high-frequency TCHMs can be divided into 6 categories: TCHMs for clearing heat and removing toxin, TCHMs for clearing heat and dampness, TCHMs for activating blood and relieving pain, TCHMs for subsiding swelling and discharging pus, astringent TCHMs for arresting bleeding, and TCHMs for eliminating dampness and relieving pain and itching. ④The herbal association rule mining showed that Jinyinhua (,Flos Lonicerae,)-Gancao (,Radix,) ,Glycyrrhizae, was a TCHM pair with relatively higher support, and Kushen (,Radix Sophorae Flavescentis,)-Jinyinhua (,Flos Lonicerae,)-Gancao (,Radix Glycyrrhizae,) was a TCHM group with relatively higher support.,Conclusion,2,Traditional Chinese medicine fumigation and washing can promote postoperative wound healing of perianal abscess. The basic treatment principle is to clear heat and remove toxin, supplemented by methods of promoting blood circulation and relieving pain, relieving swelling and expelling pus, astringing to arrest bleeding, and eliminating dampness to stop itching. Most traditional Chinese herbal medicines used are cold in property and bitter in taste.
