Highlights • Black tea affects the arterial system and change the spectrum of pressure pulse. • We proposed that black tea consumption increasing CBF may be one of possible mechanisms in lowering the risk of cognitive impairment and stroke. • Among the short-term effects of black tea on blood pressure and pulse spectrum, caffeine effect is inevitable but not a dominant effect. • Harmonic analysis could screen the overall impact of food or drug on arterial system along the time course.
