According to Dr. Huynh Tan Vu, University of Medicine and Pharmacy Hospital, Ho Chi Minh City (facility 3), green tea leaves contain many chemical components, including flavonoids, triterpen saponins, caffeine, tannine, quercetin, essential oils, ascorbic acid (vitamin C), riboflavin (vitamin B), carotene, malic acid, theophylline, xanthin, oxalic acid, kaempferol.
Thanks to these substances, green tea leaves have many effects such as stopping diarrhea, reducing the risk of cancer, protecting cardiovascular health, anti-aging, maintaining healthy bones and joints, enhancing memory, protecting the liver, controlling blood pressure, preventing complications of diabetes, and reducing the risk of infectious diseases.
Drinking tea is effective in reducing pain caused by arthritis because EGCG prevents cartilage destruction and reduces swelling. Regularly drinking tea also helps limit the development of diabetes and dangerous complications of blood sugar disease.
Tea catechins increase fat metabolism and help you lose weight safely if you combine drinking tea with exercise.
In addition, tea also has anti-toxic and detoxifying effects for the body. Tannin compounds will neutralize alkaloid toxins such as opium, strychnine, and neutralize excess iron in the body. Theobromine, theophylline and potassium salts are strong diuretics, helping the body detoxify.

According to Oriental medicine, green tea leaves are bitter, astringent, cool, and enter the Liver and Heart meridians. Green tea has diuretic, calming, cooling, thirst-quenching, digestive, and body-cooling effects.
However, you need to pay attention to the time when drinking green tea so that your health is not affected. Green tea is cold in nature, so do not drink it cold because it will cause too much cold and phlegm, so drink it hot.
Green tea contains a large amount of caffeine, which can cause dizziness, nausea, and lightheadedness if consumed on an empty stomach. Caffeine in green tea leaves stimulates the central nervous system to increase concentration and brain activity. Therefore, drinking green tea in the evening can cause difficulty falling asleep and insomnia.
You should avoid drinking green tea immediately after eating because tannins can reduce the absorption of iron and nutrients in food. Tannins in green tea have the effect of stopping diarrhea, so people with constipation should limit their use.
You should not use tea leaves for people who are taking blood thinners because of vitamin K. You should drink green tea early in the morning to stay alert and increase work and study efficiency.
