Tea leaves can t be drunk after a while after brewing, is why 20

Any type of tea should not be soaked for too long or too many times.

Soaking for too long or brewing too many times not only loses the taste of the tea soup, but also the aromatic substances and tea polyphenols contained in the tea will also be automatically oxidized; This not only reduces its nutritional value, but also exudes harmful substances. The vitamins in tea are gone.

It is best to brew and drink tea immediately, and the tea soup should be separated from the tea leaves. If it is steeped for more than a few hours, or even overnight, the tea leaves will become moldy and deteriorate; The small amounts of carbohydrates and proteins they contain can cause bacteria and mold, which can be harmful to health. This is the reason why it is not advisable to drink overnight tea.

Some families use a large porcelain pot to make a large pot of tea, and the tea soup is put together with the tea leaves for a long time or in a thermos, and the same pot of tea is drunk from morning to night, which is not conducive to health.

Do not make too strong tea, because strong tea is harmful to the stomach. People with spleen and stomach deficiency are more likely to avoid drinking strong tea. Drinking too much strong tea can cause chronic gastritis. Drinking strong tea on an empty stomach is even more taboo.

Brewing and drinking is a healthy way to drink tea.

There will be a lot of harmful substances

The tannic acid in the tea has an astringent effect, which can be combined with many drugs such as dipyrine, chlorpromazine, aminopyrine, berberine, digitalis, lactase, multi-enzyme tablets, pepsin, ferrous sulfate, soda tablets, sleeping pills, etc., which can precipitate, affecting the best effect of the drug. Tannic acid can also make constipation knotted, and people who are used to constipation should not drink tea. In addition, it is not good to drink tea immediately after meals, and overnight tea is not beneficial to the human body because all the tannic acid in the tea leaves is leached, and the ingredients in the tea are also changed.

Tea will turn reddish-brown after being left for a long time, in fact, 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 overnight tea is greatly reduced, but it still has anti-disease effects. However, the temperature is high in summer, and the tea is easy to turn rancid, so if it is left for more than 24 hours, it is best not to drink it, otherwise it will cause diarrhea.

I don't think you can drink tea after brewing it three times; Because the tea brewing times are relatively large, it will affect the taste and quality of the tea, resulting in soluble substances, and its precipitation rate is very low.

You can't drink it after four or five times, because if you drink it again, it may cause gastrointestinal problems, without any nutritional value, and there may be a lot of problems, and the impact is still very serious.

After soaking twice, you can't drink it again, because if you soak it twice, it may cause a lot of residue on it, and you may have indigestion or diarrhea after drinking.

Of course, the tea that has been brewed for a few days can no longer be drunk, and a large amount of heavy metals are precipitated in the tea.

In addition, when the temperature is high, bacteria multiply and can easily spoil, so don't drink it for your physical and mental health. Try not to leave tea overnight.

Tea leaves that have been brewed for a long time cannot be drunk.

The main reason is that the tea leaves have no taste after being brewed a few times, and they don't have any nutrition and efficacy, so they can't be drunk.

It is because if the tea leaves keep running, it is likely to cause toxins to accumulate in our bodies, and the general steeping time will not exceed 24 hours.

Because such tea leaves have no taste, and the tea will also have some bacteria, which is not helpful to the body, so I will not drink it.

After five hours of tea brewing, you should generally not drink it again. One is that the taste of the tea has been brewed out, and the other is that bacteria have begun to multiply.

Tea contains tea polyphenols, which are easily oxidized into a brown gelatinous substance in air and water - tea rust. Tea rust contains a variety of substances such as pickaxe, lead, iron, arsenic, mercury, etc.

The longer the tea is exposed to the air or left in the teacup for a long time, the more the amount of tea polyphenols oxidized into tea rust will be. Tea rust enters the human body, binds and precipitates with proteins, fats and vitamins in food, hindering the absorption and digestion of nutrients.

How long does it take for tea to be brewed before you can drink it? It's a pity that I only found out today, so I took the time to remind my family to make corrections.

A special reporter went to the test center to do the test before, as long as it is not overnight, there is no big problem with drinking tea for a day, and you can drink it with confidence.

Don't drink it for more than five hours, and try not to drink it cold.

Don't ask me why I know, I don't want to go to the toilet and come out against the wall ......

The number of brewing times of bulk tea can be a little more, about three times, but some tea bags have at most one time, because the tea bag after a brew can completely flush out the taste of the tea wrapped in it, and it is not recommended to brew it many times, because the edible taste of the tea will not be too good.

2. How to see if the tea is good or not.

Look at the color when buying tea is to observe, so that you can buy more pure tea, and the drinking taste is more fragrant and rich, you can observe the color of tea when buying tea, if the color of green tea is darker, it is recommended not to buy, because the taste of this kind of food is generally not too good.

If the aroma of tea has a certain fragrance or orchid fragrance, it is generally a relatively good tea, but if the purchased tea has a peculiar smell, it is recommended not to buy, generally this kind of tea belongs to the tea that has begun to deteriorate.

After all, the most important thing about whether tea is good or not is the drinking taste of tea, if the taste of tea is relatively light and has a certain bitter taste, it is generally a tea with excellent edible taste.

3. What is the use of leftover tea.

For hemostasis, such as stomatitis, tongue carbuncles, eczema, bleeding gums, etc., you can rinse your mouth with overnight tea**. Sores and abscesses, **bleeding can also be bathed.

The tea polyphenols in the overnight tea have antibacterial and anti-inflammatory effects, if the eyes appear red, you can wash it with overnight tea several times a day, which is very good for our eyes, and drinking tea itself can also help us to clear our purpose, you can do it together.

Hair growth is washed with overnight tea, which also has the effect of hair growth and dandruff. If you think your eyebrows are thin, you can use a brush dipped in overnight tea every day to brush your eyebrows, and after a long time, your eyebrows will naturally become thick and shiny.

Fixed teeth, clean teeth.

After the fluoride in the tea and the enamel of the teeth calcify, it will enhance the resistance to acidic substances and reduce the occurrence of tooth decay; Fluoride can also eliminate plaque, and it is best to rinse your mouth with tea two or three minutes after eating.

In addition to bad breath tea contains essential oil ingredients, the smell is aromatic, before and after brushing teeth in the morning or after meals, gargle a few mouthfuls of overnight tea, can make the breath fresh, often rinse your mouth with tea can eliminate bad breath.

The general saying is that overnight tea should not be drunk. My opinion is that you can drink it if it has not deteriorated, but "without spoilage" is difficult to define in the family, so under normal temperature conditions, you can drink it within 12 hours, and don't drink it after 12 hours.

After drinking tea for a long time, I think the biggest harm is unhygienic, and there must be a lot of bacteria; Secondly, there are things like heavy metals that precipitate more, and arsenides (arsenic), which are toxic. Maybe you don't feel good when you drink tea for a long time once or twice, but if you drink too much, it will definitely damage liver and kidney function and even cause cancer.

You can't drink it for a day, and don't drink leftover tea, it's not good for your health. Unless you put kombucha – specifically for health care.

Don't drink it! As the saying goes: new tea and old wine are good for health! Tea --- can be drunk often, not for a long time!

Overnight tea should not be drunk, it is not good for health! There is good tea to drink, and good tea will be drunk, which is a kind of blessing! May you drink tea to nourish your body, drink tea to prevent diseases, drink tea happily, drink tea happily!

Don't drink tea overnight.

The research report shows that although overnight tea is not directly related to carcinogenicity and cancer prevention, it is better not to drink it because the tea set and water quality of overnight tea do not necessarily meet the health standards; Moreover, if the tea is brewed for too long, the vitamin C and other nutrients in the tea will be reduced due to gradual oxidation, and the benefits to human health will be greatly reduced.

In addition, tea is alkaline, if the water contains too much iron, the tea may be toxic after the chemical reaction, and the tea will dissolve more tannic acid overnight, so it is easy to hurt the stomach. In addition, the proteins and sugars in tea are the medium of bacteria and molds, which are very easy to breed molds and bacteria, so it is recommended that you do not drink them.

Tea leaves cannot be drunk after brewing for more than 24 hours.

Tea leaves steeped for too long, especially in higher temperatures, will lose their green color and increase the degree of yellowness. This is the oxidation product of the oxidation of tea polyphenols in tea to form yellow-red and reddish-brown, mainly theaflavin, thearubigin, theabrownin, etc. These products are non-toxic and do not cause harm to the human body.

This change is day and night, and the temperature is higher during the day, and the change is a little bigger. However, if the tea is soaked for too long, bacteria will grow and deteriorate, so it is generally no problem to drink the tea no more than 24 hours after brewing.

The role of tea:

1. Treatment of beriberi. Tea contains a large amount of tannins, which have a strong bactericidal effect, especially for filamentous bacteria that cause athlete's foot. Therefore, people who suffer from athlete's foot will be cured after a long time by boiling tea leaves into thick juice to wash their feet every night.

However, boiling tea and washing feet must be persistent, and there will be no significant effect in a short period of time.

2. Wash silk clothes. Silk clothes are most afraid of chemical detergents. If the soaked tea leaves are used to boil water to wash silk clothes, the original color of the clothes can be maintained and shiny as new. Washing clothes made of nylon fibers has the same effect.

3. Repel mosquitoes. The used tea leaves are dried and lit at dusk in summer, which can repel mosquitoes and insects, and is absolutely harmless to the human body, and has the same effect as mosquito coils.

4. Flower fertilizer. The brewed tea still has nutrients such as inorganic salts and carbohydrate platforms, which are piled up in flower beds or pots, which can help the development and reproduction of flowers and plants.

Tea should not be drunk overnight, and tea leaves should not be drunk after brewing for a few days.

Overnight tea will produce tea polyphenols, and after the oxidation of tea polyphenols, the color of the tea will become darker, and then tea rust will be formed on the tea set, which is also not good for people's health.

In addition, overnight tea also has nitrite problems, which are similar to overnight meals. However, the nitrite content in tea is very low and not enough to cause health effects on people. If the tea is left for a long time, some shiny things will be produced on the surface, which is not a heavy metal, but is produced after the oxidation of polyphenols.

It is worth mentioning that there are a lot of particulars about drinking tea, such as green tea, which is generally not recommended to be left for too long, because the nutrients such as tea polyphenols, amino acids, and tea polysaccharides in green tea will slowly seep out within 1 hour, and if the time is too long, these nutrients will be lost.
