Global research trends on herbal tea: a bibliometric and visualized analysis

Abstract

Herbal tea, being a beverage with medicinal and edible properties, has served a significant role in promoting health and preventing diseases, leading to ongoing research advancements. This study utilizes bibliometric analysis to examine the comprehensive research status. CiteSpace was employed to conduct an analysis of the literature in the herbal tea field from 2000 to 2023, examining authorship, country and region distribution, institutional affiliations, and keyword relationships using data from the Web of Science database. The findings revealed a fluctuating yet overall upward trend in the volume of publications. China, the USA, Italy, Poland, and Malaysia emerged as the primary drivers of development in this domain. The collaboration network among authors and institutions is still in the developmental stage. Extensive cooperation can facilitate swift and sustained progress, which is urgently needed for the development of this field. Notably, there is substantial interest in the antioxidant properties of herbal tea and its phenolic compounds, particularly flavonoids, while fruit tea is emerging as a new research frontier. Furthermore, the safety aspects of herbal tea have garnered considerable research attention. There are numerous types and complex functions of herbal teas worldwide, and the regulations for their adaptation need to be improved.
