The parching green tea was made from the leaves of Camellia sinensis L. (cultivar Shy-Jih-Chun) in the spring season picked from the tea farm in Mingjian, Nantou County, Taiwan. For parching green tea, young leaves were subjected to blanching (280–300 C, 5– 6 min), rolling and drying. The dried tea leaves were ground in a mill (RT-30HS, Rong Tsong Precision Technology Co., Taichung, Taiwan), and screened through a 0.5 mm sieve.
