What tea can't drink? What are the teas that you can't drink?
On the streets of many cities, there are stalls of “selling and selling” spring tea. However, after the fried tea is bought, it cannot be immediately consumed. Nowadays, the fried tea is not only flammable, but also has not been oxidized. The content of polyphenols is high, and the content of aldehydes and alcohols is also high. It has a strong stimulating effect on the stomach and intestinal mucosa. It causes stomach pain and bloating after drinking. In addition, the current fried tea also contains more active components such as citric acid and caffeine. After drinking a lot, there will be dizziness, limb weakness and other "tea drunk" phenomenon. Therefore, after the fried tea is bought, it must be stored for at least 10 days. After the polyphenols are fully oxidized, they will be soaked and consumed. Otherwise, it will be unhealthy for your health.
During the growth and picking process, there are some pesticides or fine impurities on the surface, which are not washed before frying. Therefore, the head tea can play the role of washing tea, using boiling water below 80 °C. Half a cup of brewing, pour the tea down in about 1 minute. The washed tea leaves can be brewed.
