The concentration of caffeine and theanolide in strong tea is too high, which increases the excitability of the central nervous system, which in turn can cause accelerated gastric motility, hypersecretion of gastric parietal cells, increased gastric acid, and increased stimulation to the gastric mucosa, which can easily lead to gastric ulcers. Caffeine can also be addictive, creating a vicious cycle.

Tannic acid can combine with protein, vitamin B1 and iron ions in food, making these nutrients unable to be absorbed normally, easily causing nutrient deficiencies in the human body and producing corresponding symptoms, such as anemia, constipation and so on. Studies have shown that drinking strong tea can aggravate high blood pressure, heart disease, diabetes, nephritis, hepatitis and other conditions.
