For thousands of years, medicine men and shaman from many cultures have recognized the value of green tea in maintaining health. China Green Tips, like all Tazo green teas, is prepared in a way that maintains the natural health benefits, color and taste. The tea is steamed to neutralize the oxidating enzyme, then dried using a panfired technique to bring out the maximum flavor. Like black teas, China Green Tips and other Tazo green teas are made from the same botanical species, Cameila Sinensis and can contain as much caffeine as black teas.
