Although spring tea is not good, it is not appropriate to "freshen up".
Xi'an, on March 23rd, said that "before spring, tea is expensive." Due to the high content of free amino acids, proteins and other nutrients, the aroma and taste of the tea will be better. It is a good taste for tea lovers. However, the new tea contains many caffeine, active alkaloids and other substances, and the cold is relatively large, causing discomfort to some people. For the sake of freshness, some tea growers began picking tea before the Ching Ming Festival. This type of tea is called Mingqiancha; the tea collected before the rainy season is called pre-rain tea. From a nutritional point of view, the high levels of caffeine, active alkaloids, and various aromas in spring teas can easily stimulate the nervous system. During the spring storm, spring tea is a good drink for refreshment. However, the spring tea is a new tea that has been freshly harvested for less than a month. It contains caffeine, active alkaloids and other substances that are easy to make people excited. This has adverse effects on patients with neurasthenia and cardiovascular and cerebrovascular diseases. In addition, the new cold tea is relatively large, in which polyphenols, alcohols, aldehydes and other beneficial substances on the human have not been completely oxidized, have a stimulating effect on the stomach and stomach, easily cause stomach pain, fullness, constipation and other symptoms. Experts suggest that it is best to leave it for half a month after buying the spring tea, and then the polyphenols in the tea will be automatically oxidized before drinking.
