Bibliometric analysis of trends in research of Tripterygium wilfordii Hook F for treating rheumatoid arthritis.

Tripterygium wilfordii Hook F (TwHF) has been widely used to relieve rheumatoid arthritis (RA) in many countries. However, a bibliometric analysis of published articles discussing this treatment has not been conducted. This study aimed to explore the current status and trends of TwHF for treating RA. Literature was extracted from the Science Citation Index Expanded Database of the Web of Science from January 1, 2013 to December 31, 2022. CiteSpace and the "bibliometrix" package were adopted to analyze the number of publications, countries, institutions, journals, authors, and keywords and to draw collaborative network maps. One hundred sixty-seven articles were identified. China has the most articles, followed by the United States. The China Academy of Chinese Medical Science had the study's most significant publications and the highest centrality. The author analysis combined with the analysis of the cited authors, the rank of Lin Na is in an important position. The Journal of Ethnopharmacology, Frontiers in Pharmacology has published the most relevant articles and is the hottest related journal. For keyword analysis, "classification," "criteria," "mechanism," and "methotrexate" were still being researched hot until 2022. Further investigation showed that "TNF-α," "proliferation," "endothelial growth factor," "NF-κB," and "collagen-induced arthritis" also remains research hotspot. Our results provide information on the research status, institutions, countries, authors, published journals, keywords related to using TwHF to treat RA, and theoretical support for further research.
