It is not good to drink tea on an empty stomach outside, generally referring to green tea, oolong tea and raw tea in Pu 'er tea with high theophylline content. These teas are generally not recommended to be drunk on an empty stomach. Drinking cooked tea in Pu 'er tea on an empty stomach is not harmful to your health, so drinking cooked tea in the morning, not too strong, warms your stomach. At a suitable concentration, drinking mild Pu 'er tea does not irritate the stomach. Thick, smooth and mellow Pu 'er tea enters the stomach, forming a film attached to the surface of the stomach, which produces a beneficial protective layer for the stomach. Drinking Pu 'er tea for a long time can nourish and protect the stomach. )
Of course, tea is better than tea. Don't buy those fake ones.
