In order to deeply understand the global status and cutting-edge dynamics of the research on 3 kinds of medical Radix Glycyrrhizae，and to objectively reflect the scientific capabilities and influence of relevant research countries，institutions and individuals in this research.Methods:Using the Web of Science TM core collection database as the data sources，and Citespace as analysis sofeware.A bibliometric analysis of research papers on 3 kinds of medical Radix Glycyrrhizae from 1992 to 2018 was made.Results:A total of 2092 papers were found.These papers mainly focused on the medical and scientific research，especially pharmacology or pharmaceutics (30.31%)，chemistry (24.45%)，biochemistry or molecular biology (16.16%).Analysis of keywords with high frequency showed research hotspots in these 3 kinds of Radix Glycyrrhizae.Conclusion:The current research of these 3 kinds of Radix Glycyrrhizae can be divided into 2 phases.The first phase (1992-2003) mainly studied flavonoids and phenolic compounds in licorice root.The second stage (2004-present) focused on the extraction and separation of chemical components，the pharmacological action of major active ingredients and the expression of genes，etc.We are still in the second stage.
