Objective:To analyze the research hotspots and development trends of TCM formula granules.Methods:Literature about TCM formula granules was retrieved from CNKI from the establishment of the database to August 31, 2022. CiteSpace 5.7.R5 software was used to visually analyze the information such as literature volume, journals, research authors, research institutions, and keywords, and to draw the knowledge map.Results:Totally 1 135 articles were finally included. The number of articles published on TCM formula granules research showed a year-on-year increase. The main journals were the Chinese Journal of Experimental Traditional Medical Formulation and the Asia-Pacific Traditional Medicine. The research teams represented by Sun Dongmei and Li Junshan and the research institutions of Guangdong Yifang Pharmaceutical Co.,Ltd. and Shenwei Pharmaceutical Group Co., Ltd. were formed. The research contents mainly covered characteristic chromatogram, content determination, quality standards, standard decoction, extraction processes and so on. Conclusions:The determination of the active components of TCM formula granules, their consistency with the chemical composition of tonics and their equivalence with clinical efficacy remain hotspots for future research. At present, the research on TCM formula granules is at a developmental stage and should be further developed and cooperation between institutions and authors should be strengthened.
