目的 从文献计量学和全球专利的角度对半夏Pinelliae Rhizoma的研究现状与热点进行全面分析，为未来半夏的临床应用和深入研究提供理论指导。方法 以半夏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，将文献导入NoteExpress文献管理软件中进行查重和筛选。利用Excel、CiteSpace、VOSviewer等软件，从发文趋势与国家分布、发文机构、发文作者、关键词等维度对国内外的半夏研究现状与发展趋势进行可视化分析。通过Incopat专利数据库从专利申请趋势、全球地域分布、专利申请人及专利技术领域等方面检索并分析半夏相关全球专利申请情况。结果 共检索到符合标准的中文文献2 376篇，英文文献741篇。发文国家以中国为主，近些年来国际关注度逐渐升高。半夏领域的核心团队已经初步形成，但机构之间的合作效应尚未充分展现。近年来半夏领域中英文文献研究热点存在重叠，均聚焦于半夏及其方剂、有效成分与作用机制，且广泛运用了网络药理学等系统生物学方法。基于Incopat专利数据库检索得到专利数据16 325件，进行同族合并后得到专利13 672件，其中国内专利有13 337件，占比97.48%，占据了绝对的主导地位。结论 半夏领域的研究正不断拓展和深入，整体来看，研究正从传统中医药应用向多学科交叉、分子机制深度解析方向拓展。我国半夏专利申请量在全球专利申请格局中占据绝对主导地位，但当前仍面临专利失效数量较多、成果转化程度偏低、市场竞争力不强等现实问题。

Objective To comprehensive analyze the research status and hotspots of Banxia (Pinelliae Rhizoma) from the perspectives of bibliometrics and global patents, and to provide theoretical guidance for the future clinical application and in-depth research of Pinelliae Rhizoma.Methods The keyword “Pinelliae Rhizoma” was used to search four databases: China National Knowledge Infrastructure (CNKI), Wanfang, VIP, and Web of Science (WOS). The literature was imported into NoteExpress literature management software for duplicate checking and screening. Software such as Excel, CiteSpace, and VOSviewer were used to conduct visualization analysis of domestic and foreign research on Pinelliae Rhizoma from dimensions including publication trends and national distribution, publishing institutions, authors, and keywords. The Incopat patent database was employed to retrieve and analyze global patent applications related to Pinelliae Rhizoma in terms of patent application trends, global geographical distribution, patent applicants, and patent technical fields.Results A total of 2 376 Chinese literature and 741 English literature meeting the requirements were retrieved. China was the main publishing country, with increasing international attention in recent years. The core research teams in the field of Pinelliae Rhizoma have been preliminarily formed, while the cooperative effect between institutions has not been fully demonstrated. In recent years, research hotspots in Chinese and English literature in the field of Pinelliae Rhizoma have overlapped, focusing on Pinelliae Rhizoma and its formulas, active ingredients and action mechanisms, and widely using systems biology methods such as network pharmacology. Based on the Incopat patent database, 16 325 patent data were retrieved, and after family consolidation, 13 672 patents were obtained, among which 13 337 were domestic patents, accounting for 97.48%, occupying an absolute dominant position.Conclusion The research in the field of Pinelliae Rhizoma is continuously expanding and deepening. Overall, the research is expanding from traditional Chinese medicine applications to multidisciplinary intersections and in-depth analysis of molecular mechanisms. China occupies an absolute dominant position in the global patent applications for Pinelliae Rhizoma, but it still faces problems such as a large number of invalid patents, low transformation efficiency, and weak market competitiveness.
