Abstract： Objective： Using bibliometric methods based on CiteSpace and VOSviewer， a visual analysis of literature related to Gegen Decoction was conducted to understand the current research state，research hotspots，and trends in this field. Methods：Published research papers on Gegen Decoction were retrieved from the China National Knowledge Infrastructure （CNKI） database，covering the period from January 1，2005 to July 1，2025. CiteSpace 6.4. R1 and VOSviewer 1.6.20 softwares were employed for the visual analysis， and the co-occurrence maps of authors， research institutions，and keywords were drawn and analyzed. Results：A total of 627 research papers were included. The annual publication volume shows a fluctuating upward trend；there are 22 core authors，with the maximum number of publications being 11. The main research institutions are Guang'anmen Hospital，China Academy of Chinese Medical Sciences and Beijing University of Chinese Medicine， which carry out multi-level and cross-regional cooperative research. High-frequency keywords include "Cervical Spondylotic Radiculopathy"，"Cervical Spondylosis"，"Classical Prescription"， "Shang Han Lun （Treatise on Cold Damage）"， etc. A total of 11 keyword clustering modules were formed，such as "Gegen Decoction"，"Shang Han Lun （Treatise on Cold Damage）"，"Cervical Spondylosis"，etc.， yielding 25 burst keywords， such as "Traditional Chinese Medicine Therapy"， "COVID-19"， etc. Conclusion： Research on Gegen Decoction has shown continued growth，with clinical applications extending for different subtypes of cervical spondylosis and expanding to multi-system diseases. The research trend in this field is shifting from clinical case analysis toward pharmacological studies and mechanistic investigations.
