Urinary Tract Infections (UTIs) are a prevalent global health concern, often caused by bacterial pathogens such as Escherichia coli. In recent years, there has been a growing interest in exploring natural compounds for their therapeutic potential against UTIs. This research focuses on the phytochemical characterization of tea leaf extracts and the specific emphasis on catechin, a flavonoid known for its potent antioxidant and antimicrobial properties. The paper provides an in-depth analysis of the existing literature on the subject, highlighting the potential of catechin as a novel and effective treatment for UTIs.
