What Is Green Tea?
Green tea is produced from the leaves of the Camellia sinensis plant—the same plant used for black tea, oolong tea, and white tea. The key difference lies in processing. Green tea leaves are quickly heated (by steaming or pan-firing) after harvesting, which prevents oxidation. This preserves their natural green color, fresh flavor, and high concentration of antioxidants.
How Green Tea Differs From Other Teas
- Green Tea: Unoxidized, light flavor, high in catechins
- Black Tea: Fully oxidized, bold flavor, higher caffeine
- Oolong Tea: Partially oxidized, complex flavor
- White Tea: Minimally processed, delicate taste
Because it undergoes minimal processing, green tea retains more bioactive compounds that contribute to its health benefits.
The History and Cultural Significance of Green Tea
Green tea originated in China over 4,000 years ago. According to legend, Emperor Shen Nong discovered tea when leaves accidentally fell into his boiling water. Over centuries, green tea spread across Asia—especially to Japan, Korea, and Vietnam—where it became deeply woven into culture and spirituality.
Green Tea in Japan
Japan refined green tea cultivation and ceremony, giving rise to varieties like Sencha, Matcha, and Gyokuro. The Japanese tea ceremony emphasizes mindfulness, purity, and respect.
Green Tea in Modern Times
Today, green tea is consumed worldwide and studied extensively for its potential role in preventing chronic diseases, supporting weight management, and promoting longevity.
