Although the ancients didn't know these tricks, the refreshing effect of tea is indeed possible. For example, a dream of red mansions mentioned drinking tea and gargling. Therefore, because tea tree is unique in China or Asia, in ancient times, people discovered its various magical functions, such as refreshing the brain, removing fishy smell, and Li Qingzhao mentioned drinking group tea for health preservation when she was sick. Therefore, tea entered the palace from the folk because people discovered its magical function and because of its complicated production process, it was exclusive to the nobles for a long time until the Silk Road.

Of course, the trade in goods is also very developed, so refreshing coffee and cocoa powder flow into Europe and become drinks for nobles.
