AbstractThe genus Bidens (Asteraceae) encompasses over 240 different species. One of them is Bidens pilosa L. that is an easy‐to‐grow perennial, and broadly distributed in tropical and subtropical regions of the world. This plant has been regarded as an edible plant by the Food and Agriculture Organization of the United Nations since 1975, and has been traditionally used as a food and medicine in America, Africa, and Asia. B. pilosa has been claimed to possess active compounds with more than 40 distinct bioactivities. Although considerable progress has been made in studying the phytochemistry and biology of B. pilosa and its compounds over recent years, a critical review of its dietary functions for metabolic syndrome is unavailable. The present review summarizes the nutrition, benefits, phytochemistry, and safety of B. pilosa with respect to metabolic syndrome. As well as highlighting studies of the use of B. pilosa for metabolic syndrome, scientific evidence regarding the antimetabolic action, mechanism, and application of this species and its active phytochemicals are discussed. This review consolidates information for further study into the medicinal benefits of the compounds in this plant.
