Green tea originates from the leaves of the Camellia sinensis plant that have undergone minimal oxidation during processing. Unlike black tea, green tea leaves are typically steamed or pan-fired shortly after harvesting to prevent oxidation, which helps retain their vibrant color and a higher concentration of beneficial polyphenols, particularly catechins. These catechins, especially epigallocatechin gallate (EGCG), are powerful antioxidants believed to be responsible for many of green tea's health-promoting properties. Historically, green tea has been consumed for thousands of years, with its origins in China before spreading across Asia. It is valued not only for its distinct flavor but also for its traditional medicinal uses. Modern scientific research has extensively explored its potential benefits, leading to its widespread use as a beverage, in dietary supplements, and as an ingredient in functional foods. Its rich composition also includes vitamins, minerals, and amino acids. The bioactive compounds in green tea are thought to contribute to various physiological effects. These include modulating metabolic pathways, supporting brain health by enhancing alertness and focus, and promoting cardiovascular well-being. Its mild stimulant properties, primarily from caffeine, combined with the calming effects of L-theanine, often result in a unique state of relaxed alertness, making it a favored beverage worldwide.
