目的 从文献计量学的角度对桂枝的研究现状与热点进行全面分析，为未来桂枝的临床应用和深入研究提供理论指导。方法 以桂枝为关键词检索中国知网（CNKI）、万方（Wanfang）、维普（VIP）、Web of Science（WOS）4个数据库，检索时间设定为1990年1月1日—2025年3月31日，将文献导入NoteExpress文献管理软件中进行查重和筛选。使用Excel、CiteSpace、VOSviewer等软件，从发文趋势与国家分布、发文机构、发文作者、关键词等维度出发，对国内外桂枝研究进行可视化分析。结果 共检索到符合要求的中文文献2 476篇，英文文献591篇。在桂枝研究领域，中国中医科学院为中英文文献发文量最多的机构；王振中、Chen Lidian（陈立典）分别为中英文发文量最高的作者。桂枝研究目前处于持续发展阶段，研究热度较高，整体呈上升趋势，发文国家以中国为主，近些年国际关注度逐渐升高。桂枝领域的核心团队已经初步形成，机构间的合作效应尚未充分凸显，合作模式更多表现为医药类高等院校与其附属医院之间、同一区域科研机构之间的内部协作，跨区域、跨学科的深度合作更有待进一步拓展。桂枝领域的中英文文献均重点关注了桂枝的有效成分、作用机制等方面。从关键词分析，中文研究更聚焦于桂枝相关经典名方、医案传承及临床疾病应用，而英文研究则侧重其现代复方配伍、药理机制及网络调控路径的探讨。结论 桂枝领域的研究正不断拓展和深入，从早期对中医疗法、经典复方的关注，逐渐向成分研究、临床疾病、作用机制以及现代技术应用等多方面发展。

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.
