Herbs from the collected TCM halitosis treatment lit-erature, which met the inclusion criteria, were classified according to their effectiveness. And analysis was made on the nature, flavor and meridian entry of these herbs. Excellwas used in the descriptive analysis in the summariza-tion of halitosis medication rules. The results showed that the frequencies were 796 times which involved 149 herbs. The main nature of halitosis medication was cold, which was followed by warm and even. The total frequency was 97.49%. Sweet was the most frequently used flavor, which was followed by bitter and acrid. These three flavors ac-counted for 90.71%. The meridian entry of medicinal was mainly the stomach meridian, which was followed by the lung, spleen, heart and liver meridian. According to the effectiveness of classification, the main effect was an-tipyretic, which was followed by tonification and dampness-removing.
