INTRODUCTION
Medicinal plants have been an integral part of healthcare systems worldwide, particularly in India, which has a rich tradition of using herbal medicine as part of Ayurveda, Siddha, and Unani systems. With an estimated 8,000 medicinal plant species, India plays a crucial role in global phytochemical and pharmacological research (Levy, 2022). The increasing scientific attention toward medicinal plants has resulted in a surge of publications, with many studies focusing on their pharmacological properties, bioactive compounds, and therapeutic applications (Chaman Sab, Kappi, and Mueen Ahmed, 2022). Highly cited research papers in this field indicate key contributions that have significantly influenced the scientific community and shaped future research directions. Citations serve as a measure of the impact and relevance of scientific work, reflecting how often a particular study is referenced by researchers in the field. Highly cited papers often contribute to the foundation of emerging research areas, guiding further studies and applications (Alarcon-Ruiz et al., 2023; Trivedi et al., 2022). In the context of medicinal plants, such papers provide critical insights into ethnopharmacology, phytochemical composition, and clinical applications (Mishra, Gupta, and Shree, 2020). A scientometric analysis of highly cited research offers a systematic understanding of publication trends, influential authors, collaborative networks, and dominant research themes. Several scientometric studies have explored the landscape of medicinal plant research in India and globally (Gupta, Mueen Ahmed, and Gupta, 2018). For instance, (Jin, Lu, and Fan, 2022). Analysed publications from 2000 to 2020 and identified a growing emphasis on the pharmacological applications of Indian medicinal plants, particularly in cancer and diabetes treatment. Similarly, a bibliometric analysis by Reddy and Singh (2022) highlighted the role of Indian institutions and researchers in advancing herbal medicine studies (Rattis, Ramos, and Celes, 2021). Their study revealed that collaborations with international institutions have significantly contributed to the visibility and impact of Indian medicinal plant research. Furthermore, a recent study by (Bhatt and Pujari, 2024) focused on research trends in ethnopharmacology, emphasizing the role of traditional knowledge in modern drug discovery (Chaman Sab M, Dharani Kumar, P, Biradar, 2018). The study demonstrated that medicinal plant research is increasingly interdisciplinary, incorporating advances in biotechnology, nanotechnology, and bioinformatics to enhance the efficacy and applicability of herbal compounds.

METHODS AND TECHNIQUES
Data Collection
For the present analysis, data from the Web of Science Core Collection (WoS) (Bellis, 2009) which includes the Science Citation Index Expanded (SCIE), Social Science Citation Index (SSCI), and Arts and Humanities Citation Index (AHCI) was retrieved on January 12, 2025. The search was limited to the “Title” subject field to ensure higher precision in identifying relevant studies directly addressing the research focus. Title searches are more precise than other search methods because they focus on author-controlled=, concise titles, allowing researchers to target directly relevant publications quickly and save time (Gusenbauer, 2022). The Boolean search string was used i.e., TS=(“medicinal plants” AND “India”). The HCPs were considered as those that received 100 or more citations. The most productive authors and institutions were those that contributed a maximum more than the average number of publications the most impactful authors and institutions were those that had registered Citations per Paper (CPP) and Relative Citation Index (RCI) more than their average (Donthu et al., 2021).
Bibliometric tools and analysis
This analysis employs diverse tools to process and enhance the data and create visual representations. Microsoft Excel 2019 (v16.0) is used for primary data cleansing, filtering, and statistical analysis tools. Various scientometric software packages are also utilized to facilitate data visualization and mapping. These software packages encompassed a range of functions.
Biblioshiny (v4.1.3)
This tool developed by Aria and Cuccurullo (2017), visualizes citation networks, maps research trends, and analyses publication metrics. These biblioshily tools were used to identify key research themes, track citation patterns, and evaluate trends in this study.
VOSviewer (v1.6.18)
The visualization software developed by the Centre for Social and Technology Studies at Leiden University (van Eck and Waltman 2010) was used to analyze data and create visual maps of co-authorship networks and author keywords. The collaboration criterion for including authors was a minimum of co-authorship with at least one other author centrality, a measure of node influence based on collaboration frequency was used to assess the prominence of each author in the network. This tool encompasses a comprehensive set of bibliometric methods for analysis, making it a valuable resource for our study. In co-citation networks, two items appear together in the Bibliography of a third citing item co-occurrence networks represent relationships between items based on their frequency of appearance together in publications. Visualizations use nodes and links of various colors, with node size reflecting citation of occurrence count and link strength quantified by the Total Link Strength (TLS) parameter. Our present study utilized the detailed flow diagram provided in Figure 1.
