There are numerous varieties of Chinese Tea, each with its own characteristics; the Tea culture is profound and has a long history. Many people enjoy Drinking Tea but fear it may harm their stomach. It's a dilemma between harming the stomach by drinking tea or feeling down not drinking it at all.

In fact, there are several types of tea that do not harm the stomach and are particularly suitable for those with poor digestion.

1. Black Tea (red tea in China) Many people experience discomfort in their stomach when drinking green tea. This is because the important component in tea – tannins – have astringent properties that can stimulate the stomach, and this effect is stronger on an empty stomach. Black tea, which is fully fermented and baked, contains very little tannins after enzymatic oxidation, thus reducing its stimulatory effect on the stomach. The oxidized products of tannins (such as theaflavins and thearubigins) can also aid digestion, so black tea does not harm the stomach. Adding sugar or milk to black tea and drinking it in moderation can even be helpful as an adjunct treatment for ulcers.

Keemun black tea is one type that is highly adaptable. When sugar and milk are added, it retains its beautiful red color, which is pleasing to the eye, and its aroma and taste actually improve. Because it is suitable for blending, it is especially favored by Europeans and Americans and has become an important beverage for afternoon tea.

2. Dark Tea (Black Tea) Post-fermented dark tea contains rich nutritional components, mainly vitamins and minerals, as well as proteins, amino acids, sugars, and other substances. For residents in northwestern regions who primarily consume beef, mutton, and dairy products and lack vegetables and fruits in their diet, regular consumption of dark tea can supplement the minerals and various vitamins needed by the human body. The caffeine, vitamins, amino acids, and phospholipids in dark tea help with digestion, regulate fat metabolism, and increase the secretion of gastric juice, thereby stimulating appetite and aiding digestion.

Japanese scholars have proven that dark tea also has a strong ability to cut through grease and aid digestion, which explains why it is particularly favored by meat-eating populations.
