Do you know the magical effect of overnight tea?
What will happen to the tea leaves after a long time? The main change is that tea polyphenols are further oxidized and the color becomes darker. Because it is freshly brewed tea, the antioxidant theaflavins in the tea leaves are leached out, which is generally yellow-green. After a long time, theaflavins will gradually transform into thearubigins, and the color of the tea soup will also turn yellowish red, which is what people call the color deepening. We know that overnight tea can no longer be drunk, but do you know other benefits of overnight tea?
Benefits of Overnight Tea
1. Hemostasis: Overnight black tea is rich in tannic acid, which can accelerate blood coagulation. Mouth bleeding can be rinsed, and skin bleeding can be bathed.
2. Improving eyesight: Tea polyphenols in overnight tea have antibacterial and anti-inflammatory effects. If there is red eye, you can wash it with overnight tea several times a day.
3. Fix teeth and clean teeth: After the fluoride in loose-leaf black tea and the enamel of teeth are calcified, it will increase the resistance to acidic substances and reduce the occurrence of tooth decay; fluoride can also eliminate dental plaque. It is best to rinse your mouth with tea two or three minutes after a meal.
4. Eliminate bad breath: Decaffeinated black tea contains essential oils and has a fragrant smell. Frequent gargling with tea can eliminate bad breath.
5. Antipruritic: Wash your hair or wipe your body with warm overnight tea. The fluoride in tea can quickly relieve itching and prevent eczema.
6. Sunscreen: If the skin is sunburned, use a towel dipped in overnight tea to wipe gently. Since tannins have an astringent effect on the skin, the flavonoids in herbal green tea also have anti-radiation effects.
7. Prevent capillary hemorrhage: Rich alcohol and fluoride are contained in overnight tea, which can prevent capillary hemorrhage. If you have oral bleeding, skin bleeding, sores, swelling and poisoning, you can use it to treat. If the problem is in the nose and mouth, you can wash and gargle with overnight tea.
8. Removing fishy and greasy: Overnight sugar-free green tea also has a strong effect of removing fishy and greasy. Wash your hands after eating shrimp and crab.
9. Anti-cancer and anti-oxidation: Tea leaves will turn reddish brown after a long time. This is due to the oxidation of tea polyphenols into reddish-brown tea pigments. Studies have shown that tea polyphenols and tea pigments have strong anti-cancer and antioxidant effects. Although the content of vitamin C in tea of the previous night is greatly reduced, it still has the effect of resisting diseases.
10. Clean the house. If the painted doors and windows, furniture or glass doors and windows are stained with dust, they can be scrubbed with pure leaf green tea dregs to make them look extraordinarily bright and white. Use tea dregs to scrub the dirt on mirrors, glass, doors and windows, furniture, plastic cardboard and leather shoes, and the decontamination effect is good.
