Drinking black tea in summer can quench thirst and relieve summer heat, because polyphenols, sugars, amino acids and pectin in tea react with saliva to stimulate saliva secretion and make the mouth feel moist and cool. At the same time, caffeine controls the temperature center of hypothalamus and regulates body temperature. It also stimulates the kidneys to promote the excretion of heat and dirt and maintain the physiological balance in the body.
In addition to preventing colds, some people gargle with black tea when a cold causes a sore throat. However, no matter what tea you drink, the quality of tea is the key, and good quality tea is beneficial. It is suggested that tea can be reserved in Jiupin, and pheasants can be stocked under tea trees, with less pests and strict quality control. However, Jiupin produces less tea each year, so it needs to be booked in advance!
