Objective To summarize the herbal prescription rule of traditional Chinese medicine in treatment of imported COVID-19 cases in Tianjin. Methods From December 2019 to May 2021, the light/ordinary COVID-19 cases imported from abroad were selected as the research objects, and the cases that were effectively treated by traditional Chinese medicine were included. A database was established, and data such as patients' general information, clinical symptoms and prescriptions of traditional Chinese medicine were entered. By using data mining methods, the frequency of use of traditional Chinese medicine, high-frequency pairs and clusters of traditional Chinese medicine and prescriptions of traditional Chinese medicine were summarized. Results Totally 224 patients were included, and there were 224 treatment prescriptions, involving 148 kinds of Chinese materia medica, 35 kinds of highfrequency Chinese materia medica. The Chinese materia medica were mild in nature (1 730 times, 41.79%), bitter in taste (2 433 times, 39.23%), entering the lung meridian (3 094 times, 30.19%), clearing heat (990 times, 23.93%) and resolving phlegm, relieving cough and relieving asthma (807 times, 19.51%). Poria cocos+Pericarpium Citri Tangerinae, Pinellia ternata+Pericarpium Citri Tangerinae and Polygonum Cuspidatum+Pericarpium Citri Tangerinae are common drug pairs. Poria cocos+Pericarpium Citri Tangerinae+Polygonum Cuspidatum and Pinellia ternata+Pericarpium Citri Tangerinae+Polygonum Cuspidatum are common horn drugs. Six groups of traditional Chinese medicine clusters and six kinds of traditional Chinese medicine cluster prescriptions were obtained.
