Everyone believes that overnight tea should not be consumed, but is overnight black tea really undrinkable? Does overnight black tea have other uses? Let's briefly explore this.

Generally speaking, overnight tea loses most of its vitamins due to prolonged storage time. As long as it is not contaminated by bacteria or other pollutants...

Since overnight tea has been sitting for too long, most vitamins are lost, and proteins, sugars, and other components in the tea broth can become food for bacteria and mold to繁殖. Therefore, people usually believe that overnight tea cannot be consumed. In fact, overnight tea that has not spoiled can not only be consumed but also has the following health benefits:

Stops bleeding: Overnight tea contains abundant acid elements that can prevent capillary bleeding. For conditions like stomatitis, tongue sores, eczema, gum bleeding, etc., gargling with overnight tea can help treat them. It can also be used to wash wounds with pus or skin bleeding.

Brightens eyes: The tea polyphenols in overnight tea have antibacterial and anti-inflammatory effects. If your eyes are bloodshot, you can wash them several times a day with overnight tea.

Relieves itching: Washing your hair or wiping your body with warm overnight tea can quickly relieve itching due to the fluoride content, and it can also prevent eczema.

Promotes hair growth: Washing your hair with overnight tea can also promote hair growth and eliminate dandruff. If your eyebrows are sparse, you can dip a brush in overnight tea and brush your eyebrows daily. Over time, your eyebrows will naturally become thicker and brighter.

Sun protection: If your skin is sunburned, you can gently wipe it with a towel dipped in overnight tea. This is because tannic acid has a收敛 effect on the skin, and the flavonoid compounds in tea also have anti-radiation effects.

Removes fishy odors and grease: Overnight tea has a particularly strong ability to remove fishy smells and grease. Washing your hands with it after handling shrimp and crab will leave them feeling refreshingly clean.

When using overnight tea, it should not be spoiled (deteriorated). In summer, when temperatures are high, tea can easily sour and develop off-flavors. If it has been left for more than 24 hours, it is best not to drink it, as it may cause diarrhea.
