The American Heart Association once concluded that black tea is "one of the drinks rich in flavonoids which can eliminate free radicals and have anti-acidification effect, and can reduce the incidence of myocardial infarction". Chinese medicine believes that tea is also divided into cold and heat. For example, green tea is bitter and cold, which is suitable for drinking in summer and used to cool off the heat. Black tea and Pu 'er tea are warm, so they are more suitable for drinking in winter. As for oolong tea and Tieguanyin, they are more neutral.
Extended data
Drink black tea instead of new tea.
The newer the new tea, the better. Improper drinking is easy to hurt the stomach. Because the new tea has just been picked and stored for a short time, it contains more unoxidized polyphenols, aldehydes and alcohols, which have little impact on healthy people, but have poor gastrointestinal function.
Especially for patients with chronic gastrointestinal inflammation, these substances will stimulate the gastrointestinal mucosa, and people with poor gastrointestinal function are more likely to induce stomach diseases. Therefore, it is not advisable to drink more new tea, and don't drink new tea that has been stored for less than half a month.
In addition, new tea also contains more caffeine, active alkaloids and a variety of aromatic substances, which will also excite people's central nervous system. Patients with neurasthenia and cardiovascular and cerebrovascular diseases should drink it in moderation, and should not drink it before going to bed or on an empty stomach. The correct way is to leave it for half a month before it can be used.
