Benefits of drinking black tea in autumn
Black tea can warm the body and resist the cold.
In autumn and winter, the physiological function of human body decreases, the yang is weakened, and the requirements for energy and nutrition are higher.

The oxidation products of tea polyphenols in black tea can promote human digestion. Drinking black tea with sugar and milk often can diminish inflammation, protect gastric mucosa and have a certain effect on treating ulcers.
However, black tea is not suitable for cold drinks, which will affect the effect of nourishing and warming the stomach, and may also reduce the nutritional content because it is left for too long.
