                                According to the U.S. Department of Agriculture, a standard 8-ounce cup of green tea contains between 30 and 50 milligrams of caffeine. This fact establishes that true green tea, derived from the *Camellia sinensis* plant, always contains caffeine, though some options and alternatives offer a way to enjoy the flavor without the stimulant effect.
