1, reduce the travel.

A Dutch study of 15 years found that drinking black tea without milk can reduce the risk of stroke. American studies have found that tea polyphenols in black tea can reduce bad cholesterol 1 1%, thus reducing the risk of stroke and heart disease. Tea polyphenols can also improve vascular function.

Step 2 promote digestion

Green tea (unprocessed) helps to stimulate intestinal peristalsis and promote food digestion. Green tea can also prevent 30% fat absorption, with weight loss effect. Peppermint tea can promote digestion, ginger tea can cure nausea (especially pregnancy reaction), and fennel tea can prevent constipation, flatulence and abdominal cramps.

3. Enhance immunity

Harvard University research found that people who drink 5-6 cups of tea every day will significantly improve their immunity, metabolism and skin health. Drinking tea also helps the human body identify and fight bacteria and parasites. Ginger tea has anti-inflammatory, analgesic and circulatory stimulating effects, and can relieve migraine.

Step 4 treat insomnia

Black tea has a high caffeine content, so it is best not to drink it before going to bed. But most herbal teas do not contain caffeine. Tryptophan and amino acids in chamomile tea can play a calming role, and another substance, chrysin, can relieve anxiety, promote sleep and treat insomnia. In addition, lavender scented tea can relieve and relax. Basil leaf tea has sedative effect.

5. Protect your teeth

Although drinking tea can lead to tooth discoloration, tea polyphenols can resist bacteria and prevent dental calculus, dental diseases and dental caries. Both white tea and green tea have this effect. Fruit tea is acidic and will destroy enamel.
