The fact that green tea has a positive effect on individual organs of our body and on the whole organism as a whole has been known for a long time. Delicate tea leaves have long been an excellent remedy for lowering blood pressure, losing weight and improving immunity. And all of it beneficial features proven by scientists who determined that green tea can improve human health and increase the body's resistance to many diseases. But, how and what effect does green tea have on the liver, heart, kidneys, gastrointestinal tract? We'll talk about this today.
As part of green tea, about three hundred different chemical combinations are released, the main of which are tea caffeine (theine), theophylline, which dilates blood vessels and excites the nervous system, theobromine, which stimulates the activity of the heart, and tannin, which improves digestion and promotes good functioning of the gastrointestinal tract, and also removes radiation and microbes from our body.
Among other things, this tea contains antimicrobial substances, a lot of useful amino acids that help work nervous system, as well as various minerals (fluorine, which protects teeth from caries, phosphorus, which helps the normal functioning of nerve fibers, iodine, which prevents the occurrence of sclerosis, and others).
In addition, in green tea you will find an interesting set of organic acids, such as malic, citric, succinic or oxalic acid, which increase the healthiness of tea.
Just one cup of green tea a day can help your brain to better perceive and process the information received, increase your resistance to various stresses and infections by expanding blood vessels and saturating them with oxygen, improve visual acuity and the ability to memorize new information.
Just one cup of green tea a day for a year will allow you to lose 4-5 kg! Chinese scientists came to this conclusion a couple of years ago. Naturally, by losing excess weight, you will unload the heart and enable it to work less intensively.
Less weight - less energy to maintain the vital activity of the body, which means that you can also unload the gastrointestinal tract. Less volume of the body means that the kidneys need to work less to cleanse the body, and the liver does not need to do so much blood formation! This is the effect of green tea on the heart, kidneys, gastrointestinal tract, liver!
In addition, with a cold, green tea lowers the temperature, improves ventilation in the lungs, which contributes to a quick recovery, they can be used to gargle and rinse the nose, as it has a disinfecting and warming effect. The main thing here is not to overdo it, because at high temperatures, hot green tea can cause stress on the kidneys and heart. But in a warm form with useful herbs, lemon and honey, it will help to cope with hypothermia.
It is difficult not to pay attention to how green tea affects the heart and blood vessels. Thanks to daily use tea contributes to the fact that blood vessels expand, their walls become stronger, blood pressure decreases, and the work of the heart becomes better. Due to the fact that green tea destroys fat deposits, prevents them from being deposited on the walls of blood vessels, and also contains iron and potassium salts, blood cells begin to be produced in the body, blood improves, and the work of the heart muscles normalizes. And the presence of catechins (natural antioxidants) in tea contributes to the activation of the liver and spleen, and the rapid recovery of brain activity after a stroke.
In the work of the digestive system and the gastrointestinal tract, green tea has an antibacterial effect and acts as an antiseptic. This is because this type of tea contains special tannins that destroy harmful and pathogenic bacteria, inhibit the process of decay and decomposition, neutralize and remove toxins from the body.
In addition, these substances, having antiseptic properties, are able to heal large and small wounds of intestinal or gastric ulcers.
At the same time, quality plays an important role, because the higher the grade of green tea, the greater its antimicrobial activity and benefits for digestion.
Young tea leaves, which form the basis of green tea, perfectly cleanse the liver, stomach and kidneys, prevent the development of weakness and loss of tone of the gastrointestinal tract, help rejuvenate the body and reduce the risk of cancer.
The main thing is to remember that if the tea is too strong, then its effect on ulcers and gastritis will be negative, due to an increase in the acidity of gastric juice, because, despite the fact that green tea is very useful for the body, one should not forget that everything is good in moderation.
If, when used correctly, green tea is useful due to the presence of antioxidants and nutrients, then in large quantities (more than two cups of tea a day) it can harm the body, provoking diseases of the liver and kidneys, as this increases the content of polyphenols in the body, which are bad affect the liver.
In the rhythm of a big city, when our body is filled with toxins, poisoned with alcohol and nicotine, green tea will be an excellent health remedy that can solve or prevent many problems. Drink it, but in moderation!

However, doctors categorically disagree with traditional healers and warn against the use of these products for urolithiasis. So who is right? We will try to find the answer to this question in our article.
Chemical composition
To understand how useful or harmful green tea is for kidney stones, you need to study its chemical composition, as well as analyze in detail the effect of this drink on the human body. According to scientists who have studied the chemical composition of this drink, it is a real storehouse of useful trace elements and substances that have a beneficial healing effect on our body.
Green tea has great benefits due to the presence in its composition of the following trace elements, substances and compounds:
- Tannins. 1/3 of this drink is tannins. However, their benefits or harms are still debated. For example, caffeine tannate stimulates our cardiovascular system and central nervous system. And tannin in green tea is twice as much as in black.
- Alkaloids, namely theobromine and theophylline, promote vasodilation. And the concentration of caffeine in this drink can reach up to 4%, which is even more than in natural coffee.
- Enzymes and amino acids. This product is considered low-calorie, since only protein substances are present in its composition.
- Vitamins. Leaf green tea contains 4 times more vitamin P than citrus fruits. He is also a champion in the content of vitamin C. Moreover, the vitamins of these two groups in a pair enhance medicinal properties each other. They increase our immunity and protect cells from damage and destruction. In addition, green tea contains 6 times more carotene (provitamin A) than carrots. This vitamin is responsible for the clarity of vision and helps to remove free radicals from the body. The drink also contains vitamins B and E. They are responsible for our beauty, help fight viruses and bacteria, and have an antioxidant effect.
- Minerals and trace elements. Green leaf tea contains phosphorus, potassium, iodine, fluorine, calcium, gold, magnesium and sodium. Also in the fresh leaf there are essential oils that volatilize during processing.
Important: the Chinese use green tea to treat about 400 different ailments and rightfully consider it the best natural healer.

Attention: in case of excessive consumption, green tea can lead to the exact opposite effect - it will contribute to the deposition of kidney stones.
Contraindications
- First of all, this applies to people in old age. In them, the drink is able to provoke the development of rheumatoid arthritis and gout.
- In the presence of kidney failure, it is also recommended to drink no more than one cup of this tea per day.
These contraindications are due to the fact that during the life of the cells of our body a by-product is released - uric acid (purine). This substance is excreted from the body by the kidneys. However, green tea has its own purines that make this process much more difficult. As a result, the load on the kidneys increases, due to which the excretory process slows down. The body accumulates uric acid, which penetrates into the intraarticular fluid. There, it begins to crystallize and form salt clots. This is how gout develops.
Important: if you drink more than three cups of tea a day, then the risk of stone formation in the gallbladder and kidneys increases. This effect of the drink is associated with the presence of polyphenols in its composition.
Moreover, if you already suffer from urolithiasis or you have gallstones, then it is better to stop drinking green tea altogether. Other possible contraindications to its use are associated with the following effect of the drink:
- It can increase the acidity of gastric juice, so you should not drink it with exacerbation of gastritis, the presence of erosion in the digestive organs, and also in the stage of exacerbation of peptic ulcer.
- If you drink it at a high temperature, then the load on the kidneys increases several times.
- In the case of combining the intake of alcohol and green tea, the load on the kidneys also increases.
- With caution, you should drink it in the presence of insomnia, severe arrhythmias, high blood pressure and anxiety.
- A stale drink increases the concentration of purines, which is very dangerous for people with glaucoma, gout and hypertension.
Tea for urolithiasis
Despite the extensive list of useful antioxidant, anti-inflammatory, soothing and tonic properties of the drink, it is not recommended to drink it with urolithiasis. It is explained simply. It turns out that in case of violation of metabolic processes in the human body and the deposition of kidney stones, this drink will contribute to even greater stone formation. And this fact has been confirmed by scientific research.
Of course, such a person can afford a couple of cups of green tea with milk a day. They not only do no harm, but also have a weak diuretic effect. However, the abuse of this tea can worsen the course of your disease. But this drink also has the opposite effect. If a person has urate and urate-oxalate stones, tea drunk after a meal helps to improve the digestion of meat and fatty foods, which is especially important for urolithiasis.
The benefits of drinking green tea with milk are explained as follows:
- Calcium found in milk binds in the intestines to green tea oxalates.
- This substance is excreted through the intestines during defecation.
- That is, in this case, calcium oxalate does not enter the urinary system, where it can cause the formation of stones.
In conclusion, we can say the following: for people with urolithiasis, green tea with milk is much more useful than a simple drink undiluted with milk, and even more so, it is much better than black tea.
Today we will tell you about who is contraindicated in green tea. In addition, from the presented article you will learn what composition this product has and what healing properties it has.
general information
Before telling you about who is contraindicated in green tea, you should tell about this drink in more detail.
Green tea is tea that has undergone minimal fermentation (i.e. oxidation). At the same time, few people know that both green and black drinks are obtained from the leaves of the same tea bush. Then what is the difference between them? The fact is that the leaves for obtaining the mentioned teas are extracted completely different ways. Without going into details, I would like to note that the raw materials for the green drink are pre-oxidized by 3-12%.
Green tea: benefits, composition

Moreover, these substances are contained in such a drink twice as much as in black. That is why it should be included in your diet for those who regularly suffer from constipation and other bowel problems.
It should also be noted that the combination of caffeine with tannin forms the substance caffeine tannate. It is it that acts as a stimulant on the cardiovascular and nervous system.
alkaloids
Contraindications of green tea, as well as the benefits, are due to its composition. As we found out above, this drink contains caffeine. As a rule, its amount is approximately 1-4%. Its exact content depends on many factors (for example, the size of the tea leaves, processing method, growing conditions, water temperature during brewing, etc.). In addition to caffeine, this product also contains other alkaloids in the form of theobromine and theophylline, which promote vasodilation.

A very important place in this drink is occupied by B vitamins. So, B1 helps regulate the carbohydrate balance of the body, and B2 fights viruses and bacteria, helps strengthen hair and nails. As for vitamin B3, it reduces the amount of cholesterol and enhances the production of red blood cells.
Among other things, green tea is also very rich in vitamin E, which strengthens cell membranes and has an antioxidant effect on the human body. It also has a positive effect on the reproductive system - both men and women.

Cooking any tea drink, including green, is called brewing. To do this, take about 2 g of dry matter and pour it with about 100 ml of boiled water.
It should also be noted that the brewing process can vary markedly depending on which grade of product you have purchased. For example, for high-quality tea, a large amount of dry leaf is used, which can be brewed several times in a short time.
The preparation time of the drink and the temperature of the water are also different for different varieties tea. The highest brewing temperature is 81-87°C and the longest time is 2-3 minutes. As for the lowest value, it is 61-69°C and 30 seconds, respectively.
As a rule, low-quality tea is brewed at higher temperatures and much longer than high-quality tea. It is by this observation that you can determine which product was sold to you in the store.
Finally, I would like to add that if green tea is brewed for too long and in boiling water, it will become astringent and bitter, regardless of its variety and quality.
