Black tea is made by fermentation and baking. Black tea is mild in nature and mellow in taste.

Efficacy of black tea: Black tea is rich in flavonoids and potassium. Flavonoids have a strong antioxidant effect, while potassium is beneficial to heart health and can prevent stroke and heart disease. Generally, tea polyphenols contained in green tea have astringent taste, which has a certain stimulating effect on gastric mucosa, especially on an empty stomach. On the other hand, black tea is fermented and baked. Tea polyphenols are enzymatically oxidized by oxidase. The stimulating effect on gastric mucosa is greatly weakened. Moreover, the oxidation products of these tea polyphenols can also promote gastrointestinal digestion.

Therefore, black tea will not only hurt the stomach, but also nourish the stomach. Drinking black tea with sugar and milk often can diminish inflammation, protect gastric mucosa and have certain curative effect on treating gastric ulcer. Drink black tea while it is hot. It tastes good and warms the stomach. If you drink it cold, it will not only hurt your stomach, but also reduce the nutrients because it is left for too long. Black tea itself has a heavy taste, so there is no need to take more from Chata when brewing.
