Abstract

Essential oils, aromatic compounds extracted from various parts of plants, have garnered significant attention in recent years due to their diverse therapeutic properties and potential applications in healthcare. This analysis delves into the publication trends, productivity patterns, most relevant contributors, coauthorship networks, most frequently used keywords, and their co-occurrence, topic trends, thematic evolution, and collaboration between various countries in clinical trials exploring the therapeutic potential of essential oils. Six hundred sixty-one clinical trials were selected from the PubMed database for analysis, authored by 2959 authors, and published across 359 sources. The analysis identified Horrobin DF as the most contributing author based on the number of published clinical trials, followed by Kasper S, McGuire JA, and Schlafke S. Lotka's law underscores the distribution of authors' productivity, revealing a small number of highly productive authors. Coauthorship analysis identifies significant collaborations among authors and institutions, with prominent contributors like Siegfried Kasper and institutions like Shiraz University of Medical Sciences. Furthermore, the analysis highlights leading journals like Complementary Therapies in Clinical Practice and the Journal of Alternative and Complementary Medicine. Using keyword clustering, connections between various subjects and their chronological presence are uncovered, offering insights into the changing research landscape. The thematic examination exposes changes in research emphasis over time, progressing from fundamental studies on essential oil components to broader utilization and focused inquiries into oils and therapeutic domains. Analysis of the countries of corresponding authors revealed that Iran has the highest number of multiple-country publications. Moreover, international collaboration trends have been unveiled. Together, these analyses furnish holistic understandings of keyword relationships, thematic shifts, and global partnerships in essential oil research, presenting valuable perspectives on trends and focal points within this domain.
