Don't throw away used tea leaves - there are really plenty of handy life hacks

Friends, after you finish brewing tea,
never throw the leaves away,
keep them - they still have many uses!
Eliminating eye bags
If the green tea bags we've already brewed are still slightly warm, applying them under the eyes before bed can promote blood circulation and improve dark circles and eye bags. If the eye area is puffy, freeze the tea bags and use them in the morning.
Removing foot odor
The tannic acid abundantly found in green tea has a strong sterilizing effect. Friends with athlete's foot and foot odor can add boiled strong tea liquid to the water when soaking their feet before bed. After sticking with it for a period of time, the condition will improve noticeably. For general fatigue, green tea foot soaks can also be used, and the effect of relieving fatigue is quite good too.
Relieving bad breath
The alkalinity of tea can neutralize acidic substances in our bodies. Holding tea leaves in the mouth, or rinsing the mouth with strong tea in the morning, can both solve this problem well.
Promoting blood circulation and resolving blood stasis
In daily life, bruises from bumps and knocks are unavoidable. Apply a wet tea bag to the bruised area for about 5 minutes; it can help constrict blood vessels, thereby disinfecting and sterilizing, and relieving swelling and inflammation.
Stopping bleeding and calming
Mouth ulcers and bleeding gums can also be relieved with tea bags. Hold a wet tea bag in the mouth and press it against the bleeding area; the tannic acid in the tea leaves can exert an anti-inflammatory and healing effect, relieve pain, and also form a natural protective film.
Repairing dryness
Cracked heels and peeling lips are also very common problems, and they keep coming back without getting better. Besides lack of water, it may also be caused by cell damage. Try applying a wet tea bag to the lips or heels about 3-5 times a week; stick with this method for a period of time and the condition will improve.
Cleaning dirt
The tannic acid in tea leaves can effectively break down and soften dirt. Dirt on mirror surfaces and grease stains on glass bottles can all be wiped away with tea leaves.
Eliminating odors
Does your home always have strange smells and you don't know how to get rid of them? Heat tea leaves in the microwave, then wrap them in gauze and place them in the refrigerator, kitchen, bathroom, shoe cabinet, wardrobe and other places; the tea leaves can absorb odors. In addition, if fishy smells remain on tableware, just throw tea leaves in and boil for a few minutes, and the odors can be removed quite smoothly.
Removing rust from iron pots
Iron pots are especially prone to rusting, which both affects health and shortens the service life of the iron pot. First wash the pot clean, then apply a wet tea bag to the inside of the pot; the tannic acid contained in the tea leaves will form a protective film in the pot, preventing the iron pot from oxidizing and rusting.
Growing flowers and plants
Brewed tea leaves still retain nutrients such as inorganic salts and carbohydrates, so spreading them or burying them in flower pots and soil can promote plant growth.
