Abstract： Objective： To analyze the medication patterns of traditional Chinese medicine in treating frequent urination using the Ancient and Modern Medical Case Cloud Platform. Methods： Relevant literature on traditional Chinese medicine treatment of frequent urination published from the inception of the databases to July 31， 2025 was retrieved from China National Knowledge Infrastructure（ CNKI），Wanfang Data Knowledge Service Platform（ Wanfang）， and China Science and Technology Journal Database （VIP）. Prescription data were extracted， and the data mining module of the Ancient and Modern Medical Case Cloud Platform was used for frequency analysis， property analysis， association analysis， hierarchical cluster analysis， and complex network analysis. Results： A total of 122 Chinese medicine prescriptions were retrieved，involving 205 Chinese herbs. The top five herbs in terms of frequency of use were Glycyrrhizae Radix et Rhizoma，Alpiniae Oxyphyllae Fructus，Astragali Radix，Poria，and Dioscoreae Rhizoma. The dominant medicinal properties were neutral，the dominant flavor was sweet，and the primary meridian tropism was the kidney. The main therapeutic effects were clearing heat and removing toxicity， and arresting emission and reducing urination. Association rule analysis showed that the top three herb pairs were Alpiniae Oxyphyllae Fructus-Mantidis Ootheca， Alpiniae Oxyphyllae Fructus-Dioscoreae Rhizoma， and Alpiniae Oxyphyllae Fructus-Astragali Radix. Cluster analysis identified three clusters. The core prescription derived from complex network analysis was modified Suoquan Pills plus Sijunzi Decoction. Conclusion： Traditional Chinese medicine treatment of frequent urination primarily focuses on arresting emission and reducing urination，and clearing heat and removing toxicity，supplemented by tonifying the spleen and benefiting qi， and draining dampness and relieving strangury. The treatment emphasizes sweet and neutral herbs acting on the kidney with holistic regulation， reflecting the characteristics of syndrome differentiation and individualized treatment.
