China is the birthplace of tea trees, which first appeared in Yunnan-Guizhou Plateau and Xishuangbanna in southwest China. Shennong Herbal Classic is the first pharmaceutical monograph in China, which was written in the Warring States Period and completed in the Western Han Dynasty. In the form of legend, this book collects the drug knowledge accumulated by the working people for a long time since ancient times, including a paragraph that says: "Shennong tasted a hundred herbs, but it was poisoned by seven or two poisons every day, but it was solved in tea." According to textual research, the tea here refers to ancient tea, to the effect that in ancient times, the legendary Emperor Yan personally tasted all the herbs in order to find plants beneficial to human survival and was poisoned many times in one day. But he was saved by tea. Although this is an obviously exaggerated legend, we can also learn from it that the use of tea by human beings may have started from medicinal use. This is the earliest record of health tea.
Drinking health tea is very helpful to all aspects of the body. Drinking a cup of health tea every day is a good choice for people. But we should pay attention to reduce the intake of health tea at night, and drinking too much at night is not good for our health.
There are also exquisite teas of different constitutions. People with hot and dry constitution should drink herbal tea, while those with deficient and cold constitution should drink warm tea. People who feel bloating after eating bitter gourd and watermelon should drink neutral tea or warm tea, patients with low immunity or long illness can take Lingzhi tea, and the elderly should drink black tea and Pu 'er tea.
