Abstract：Objective：To explore the medication rules and formulation characteristics of Chinese medicine in the treatment of bronchial asthma in the Lingnan region based on literature analysis. Methods： Literature on Chinese medicine treatment of bronchial asthma in the Lingnan region from January 2000 to March 2024 was retrieved from CNKI， VIP， Wanfang， Chinese Medical Journal Full-text Database， and SinoMed. A database of the selected prescriptions and herbs was established. Data mining techniques were used to perform frequency analysis，analysis of natures， flavors， channel entry and efficacy， association rules analysis， and cluster analysis on the medicines. Results：A total of 58 eligible articles were included，involving 71 prescriptions and 118 types of Chinese medicines. The natures of the medicines were mainly cold， warm， and neutral， with bitter， acrid， and sweet flavors being predominant； the medicines primarily targeted the lung， spleen， stomach， heart， and kidney meridians. K-means cluster analysis identified four clusters of prescriptions. Conclusion：Chinese medicine treatment of bronchial asthma in the Lingnan region emphasizes clearing lung and dissolving phlegm，relieving cough and panting，and fortifying the spleen and boosting the kidney. It also considers the use of exterior-releasing and heat-clearing medicines， often combined with herbs that dispel dampness and strengthen the spleen， utilizing locally sourced Lingnan medicinal materials. This provides an effective reference for Chinese medicine treatment of bronchial asthma in the Lingnan region.
