Objective To comprehensively analyze the research status and hotspots of Guizhi (Cinnamomi Ramulus) from the perspective of bibliometrics, so as to provide theoretical guidance for the clinical application and in-depth research of Cinnamomi Ramulus in the future. Methods The four databases, namely CNKI, Wanfang, VIP, and Web of Science (WOS), were searched with Cinnamomi Ramulus as the keyword. The retrieval time was set from January 1, 1990 to March 31, 2025. The literatures were imported into NoteExpress literature management software for duplicate checking and screening. Software such as Excel, CiteSpace, and VOSviewer were used to conduct visual analysis on domestic and foreign researches on Cinnamomi Ramulus from the dimensions of publication trends and national distribution, publication institutions, publication authors, keywords, etc. Results A total of 2 476 Chinese literatures and 591 English literatures met the inclusion criteria. In the field of Cinnamomi Ramulus research, the China Academy of Chinese Medical Sciences ranks first in the number of published papers in both Chinese and English. Wang Zhenzhong and Chen Lidian respectively hold the highest number of publications in Chinese and English in this field. Research on Cinnamomi Ramulus is currently in a sustained development phase with high overall research heat, showing an upward trend. China is the primary contributing country, with gradually increasing international attention in recent years. Core research teams in this field have initially formed, butcooperative effect among institutions has not yet been fully highlight, the cooperation model is more often manifested as internal collaboration between medical colleges and their affiliated hospitals, as well as among research institutions within the same region. Deeper cooperation across regions and disciplines still needs to be further expanded. In the field of Cinnamomi Ramulus research, both Chinese and English literatures have focused on aspects such as its active components and mechanisms of action. From the perspective of keyword analysis, Chinese studies have paid more attention to classic famous prescriptions related to Cinnamomi Ramulus, the inheritance of medical cases, and clinical disease applications, while English studies have emphasized the exploration of its modern compound compatibility, pharmacological mechanisms, and network regulatory pathways. Conclusion Research in the field of Cinnamomi Ramulus is continuously expanding and deepening, evolving from early focus on traditional Chinese medical therapies and classical formulas to multi-faceted investigations covering component research, clinical diseases, action mechanisms, and modern technological applications.
