Abstract: Camellia sinensis (L.) is acknowledged globally as the second most consumed beverage
after water. Researchers have dedicated substantial efforts to validate the claims surrounding this
plant through rigorous pharmacological screening, aiming to substantiate its traditional applications
in treating various ailments. This work extensively delves into aspects such as marketed formulations
of green tea, extraction techniques, phytochemistry, pharmacology, interactions between drugs and
green tea, and its distinctive characteristics. Key research unequivocally suggests that green tea holds
substantial health benefits for individuals. Presently, a multitude of pharmacologically active constituents
have been successfully isolated and identified from green tea, encompassing polyphenols, alkaloids,
amino acids, polysaccharides, and volatile components. Recent investigations have illuminated
the broad spectrum of pharmacological properties exhibited by green tea, encompassing antioxidant,
anticancer, hypoglycemic, antibacterial, antiviral, and neuroprotective attributes. The review amalgamates
current research findings to present a thorough understanding of the diverse bioactive compounds
found in Camellia sinensis, such as polyphenols, catechins, and alkaloids, and their contributions
to its health-promoting properties. The review further highlights the significance of extraction
techniques in preserving and enhancing the bioactivity of these compounds. Overall, this comprehensive
review serves as a valuable resource for researchers, practitioners, and enthusiasts, consolidating
the current knowledge surrounding Camellia sinensis and its multifaceted role in promoting human
health.
