Ferment process cause compound of polyphenol at tea will
experience ofoxidation so that level of polyphenol will decrease, therefore
level ofpolyphenol highest at green tea and lowest at black tea. Compound
polyphenol attea function to assist activity of enzyme superoxide dismutase (
SOD ) doingdefense of free radical. Tea also contain alkaloid like caffeine
thatfunctioning as a diuretic. Important mineral at tea is phosphorus for

assuage eye fatigue.
To look after health be recommended consume tea and in serving tea can be mixedwith milk because addition of milk can lessen side effects some element in tea,this matter go together tendency one who consume tea without milk have level ofoxalate higher. Conglomeration of oxalat in part people can cause renaldisease, therefore the risk can be lessened with milk mixture at tea becausecalcium at milk will becomes one with oxalate and finally oxalate exit withurine. To obtain benefit of tea optimally better don't pour boiling water intotea too long time because if progressively soaked hence caffeine in tea willprogressively experiencing of extraction so that happened oxidation. If we wantto get more condensed tea be done with addition portion of tea leaf non withprolong infusion time.
