Green tea (Camellia sinensis), one of the most widely consumed beverages globally, has gained remarkable attention for its rich phytochemical profile and diverse health-promoting properties. Traditionally consumed in countries such as China, Japan, Korea, and North Africa, green tea is increasingly becoming popular worldwide owing to its bioactive compounds, including polyphenols, catechins, tannins, gallic acid, and an array of vitamins and minerals. These constituents exert powerful antioxidant, anti-inflammatory, and antimicrobial activities that contribute to their therapeutic potential. The increasing scientific evidence suggests that green tea plays a pivotal role in the prevention and management of various chronic diseases, particularly by suppressing tumor progression, modulating metabolic disorders, enhancing wound healing, and improving cardiovascular and neurological health. The ability of green tea to mitigate oxidative stress and regulate cellular signaling pathways underscores its role in maintaining overall well-being. This review aims to comprehensively explore the phytochemistry of green tea, highlighting its major bioactive components and their mechanistic actions on human health. Special emphasis is placed on the therapeutic potential of catechins, particularly epigallocatechin gallate (EGCG), which has been extensively studied for its anticancer, cardioprotective, and neuroprotective effects. By integrating phytochemical insights with recent advancements in biomedical research, this review underscores green tea as a natural, functional beverage with profound implications for disease prevention and health promotion.
