Green tea, known in Chinese as lǜchá (绿茶), is celebrated worldwide for its fresh flavor and vibrant color, but its reputation in traditional Chinese health culture extends far beyond mere taste. For centuries, practitioners of Traditional Chinese Medicine (TCM) and everyday folk healers have regarded green tea as a versatile herb that supports balance within the body’s energetic systems. Unlike modern clinical claims, these traditional perspectives are rooted in observational wisdom, classical texts, and seasonal customs that have been passed down through generations. This article explores those time‑honored views, explaining how green tea was historically understood to influence health, what specific benefits were attributed to it, and how those ideas continue to shape tea‑drinking habits today. Throughout, the emphasis remains on traditional understanding rather than medical conclusions, offering tea enthusiasts a cultural lens through which to appreciate this unfermented leaf.

Later, the Tang dynasty scholar Lu Yu’s seminal work Chájīng (茶经, The Classic of Tea, 8th century CE) systematized tea cultivation, preparation, and consumption, explicitly noting that “tea tempers the heart, dispels fatigue, and aids digestion.” Lu Yu’s observations were not isolated; they reflected a broader TCM framework that classified foods and herbs by their energetic properties—hán (cold), wēn (warm), (hot), and píng (neutral)—and their effects on the body’s (vital energy) and organ systems.

During the Song dynasty (960–1279 CE), tea drinking became an integral part of scholarly and monastic life. Monastic records from Chan (Zen) Buddhism describe how monks used green tea to maintain alertness during long meditation sessions, attribut
