Chemical composition of the product
Green tea contains vitamins, minerals, amino acids, catechins, theanine, caffeine and pectin
Green tea leaves contain many different chemical components - more than 2000. Most of them are beneficial to the body and have a positive effect on overall health.
But some substances can be harmful to health, so you need to familiarize yourself with them before using green tea.
China is considered the birthplace of this plant, where they began to brew it and use it as a healing drink.
When dried, the plant does not lose its beneficial properties and all the substances in the composition remain:
- Vitamins are needed to maintain the functioning of the entire body. Their individual groups influence different processes in organisms. They take an active part in hematopoiesis, cell regeneration, and have a general strengthening effect on the body.
- Minerals are used for normal intracellular metabolism, normalize water balance, and maintain the strength of osteochondral tissues.
- Amino acids support metabolism, normalize the functioning of all organs and systems, and promote cell renewal.
- Pectin is a natural fiber that accelerates fat metabolism. Thanks to them, cholesterol is removed - fat of plant and animal origin, which can settle in blood vessels and cause atherosclerosis.
- Catechins are flavonoids and polyphenols. These are the strongest natural antioxidants that bind the negative effects of free radicals in the body. These substances increase the body's protective functions and improve immunity. Epigallocatechin gallate in its healing properties surpasses the action and benefits of vitamins E and C, which are considered the strongest for the immune system.
- Theanine is an amino acid that reduces the effects of caffeine and has a calming effect. Therefore, it is recommended to drink green tea in case of disruption of the central nervous system. However, theanine does not have a hypnotic effect. It acts as an antidepressant.
- Caffeine adds a bitter taste. In addition, it helps increase blood pressure and has a vasoconstrictor and diuretic effect. In addition, it accelerates blood circulation and stimulates the nervous system.
Due to such a rich composition, green tea has many beneficial properties that affect all aspects of life processes.
Properties of black tea
Compared to coffee, black tea contains less caffeine, which promotes blood flow to the brain without putting extra strain on the heart. Although coffee prepared according to the rules is also useful.
Black tea contains a lot of tannins. It has a calming and anti-inflammatory effect on the digestive organs.

- tannin and caffeine, stimulating the functions of the nervous system.
Hot tea helps ease the respiratory system in patients suffering from asthma. This occurs due to the expansion of the respiratory tract under the influence of the drink.

Black tea stimulates the digestive system. It is able to eliminate bacteria and viruses that cause infection and inflammation in the body. With the help of the drink, dysfunction of the coronary arteries is corrected.

How does it affect blood vessels?
Cardiovascular disease is a serious and dangerous illness.
The main mission of the heart and blood vessels is to saturate the body with oxygen. They also help “charge” cells with energy. Share “Tea for the heart and blood vessels”
Back in the 70s of the last century, the Russian physiologist Protodyakonova was engaged in an experimental study of lactic acid, high-energy phosphates and glycogens, which are contained in the heart muscle, and also showed the values of rat lactic acid after the introduction of caffeine. As a result, it was found that this substance has an extremely beneficial effect on the functioning of the heart muscle, strengthening it, not to mention increasing the elasticity of blood vessels.
People sometimes ask, which chocolate is good for the heart? This is considered a product containing at least 70% cocoa.
We can talk about the benefits of chocolate only when it is not full of sugar and other fillers. That is, we are not talking about milk or white chocolate. This does not include a variety of candies and chocolate desserts, in which chocolate is present only in the name, and in their composition there are so many unnecessary additives, thanks to which these products turn out to be, at best, useless for the heart.
- cardiac ischemia;
- atherosclerosis;
- heart failure;
- endocarditis;
- myocarditis.
Herbal tea affects the heart at a “deep” level. It contains potassium, which is necessary for the proper functioning of the heart muscle.
Interesting to know: Tea reduces the amount of substances that deplete the heart muscle and protects the heart from heart attacks. Tea also strengthens the walls of blood vessels and capillaries. This is especially important for older people.
Tea has a diuretic effect, removes excess fluid from the body, relieves swelling, and is recommended when cleansing the body of toxins and waste. Excess fluid puts a heavy burden on the heart and blood vessels, so such cleansing must be done regularly.
When a person suffers from headaches, migraines, hearing and vision have deteriorated, and fatigue begins to be felt - this is due to the fact that the blood vessels of the brain narrow and lead to painful sensations. Green tea helps relieve pain. True, it has different effects on vascular areas.
As you age, it is extremely important to strengthen your heart, especially for those people who have once had a heart attack. As practice shows, this goal can be achieved without additional and often expensive pharmaceutical medications. In folk medicine, there are a huge number of herbal infusions that can be used in the form of tea leaves.
If you really want to take care of your “engine,” then it’s better to buy a bar of dark chocolate, or any kind in which the majority is cocoa beans and the least amount of sugar.
Scientists compared the effects of dark, milk and white chocolate on platelet function by comparing venous blood samples taken from healthy volunteers before and after consuming these products. Milk and white chocolate had virtually no effect on platelet function, but dark chocolate slowed down the process of platelet aggregation, that is, thrombus formation, and this is an extremely important point in the prevention of thromboembolic and cardiovascular diseases.
It is important to know: if migraines are caused by vascular spasms, then green tea will not have a positive effect. The pain will only get worse. Individual tolerance to tea should be taken into account.
"Our findings may also explain why the health benefits of tea for heart disease are missing in the UK, a country where tea is usually drunk with milk," said Stangl, professor of cardiology. According to the researchers, the vascular protective effect of black tea is due to increased production of nitric oxide, which relaxes the veins. However, three caseins from milk interfered with this effect, presumably in combination with protective catechins from tea.
How to brew tea correctly
Green tea should be brewed with barely boiling water.
There are several secrets to brewing tea, thanks to which it will not only be healthy, but also very tasty.
The most important points for getting a good drink are high-quality water and high-quality tea leaves. You cannot take water from the tap. Ideally, you need spring water for tea, but in city conditions purified filtered water is suitable.
Next - dishes. Do not use a metal container. Ideally, tea is brewed in a porcelain or ceramic teapot. The water should be “white spring” - this is a state when it has not completely boiled, but bubbles have just begun to appear.
Let's look at the step-by-step instructions for brewing green tea:
- Boil water in a kettle and prepare the teapot.
- When the water starts to boil, you need to turn it off and wait a couple of minutes for it to cool to 80 degrees.
- The teapot needs to be warmed up; to do this, add a couple of tablespoons of boiling water.
- Next, the tea leaves are poured at the rate of one teaspoon of tea per cup of boiling water.
- Pour boiling water into the teapot and wait 4-5 minutes.
It is recommended to use large-leaf tea; it is considered to be of the highest quality - tasty and healthy.

- The duration of the brewing depends on what it is done for. To increase blood pressure and tone of blood vessels, drink tea 1.5 minutes after the start of brewing. If you need to lower blood pressure and dilate blood vessels in the brain, drink green tea, which is brewed for 3-5 minutes.
- To improve the taste of tea, sugar, honey, lemon, rosehip or hawthorn syrup are used.
- Every day you can drink no more than 0.5 liters of green tea, and at the same time you should drink at least 1.5 liters of water. Tea removes excess fluid from the body, for this reason it should be replenished.
