Licorice root, derived from the Glycyrrhiza species, has been used for centuries in traditional medicine for its various health benefits. In recent years, research has shed light on its interactions with the gut microbiome, the complex community of microorganisms residing in the gastrointestinal tract. This article provides a thorough examination of the relationship between licorice root and the gut microbiome. It explores the bioactive compounds present in licorice root, their potential effects on gut microbial composition and diversity, and the implications for gut health and overall well-being. Furthermore, the article discusses the challenges and opportunities in harnessing the gut-modulating properties of licorice root for future therapeutic applications.
Introduction:
