Essential oils. It is from essential oils depends on the quality of the tea. They seem to be very few (about 0.02%), but their role is huge - essential oils give tea its unique aroma. When processing tea leaves, the loss of essential oils reaches 70-80%.

alkaloids. Among them, the most famous is caffeine. Acting in tea along with tannin, caffeine forms the compound caffeine tannate, which has a milder effect on the cardiovascular and central nervous systems than the caffeine present in coffee. In addition to caffeine, tea contains small amounts of other alkaloids - water-soluble theobromine and theophylline, which are good vasodilators and diuretics.

Amino acids. Glutamic acid was found in tea, which is important for the human body: it normalizes metabolic processes, helps to restore depleted nervous system.

Green tea is rich in vitamins K, B1 (thiamine), B2 (riboflavin), B9 (folic acid), B12, PP (nicotinic acid).

Tea also contains vitamin C (ascorbic acid). in green and yellow teas vitamin C is 10 times more than in black. Vitamin P in green tea is 4 times more than in oranges or lemons. In combination with vitamin C, it significantly enhances the effectiveness of ascorbic acid, promotes its accumulation and retention in the body.

Thus, green tea is a treasure trove of substances useful for humans.

Contraindications for green tea:

Despite all positive properties green tea, do not abuse it. Since green tea lowers blood pressure, hypotensive patients should not drink it. You can not get involved in green tea with:

acute form of hypertension;

any diseases in the acute phase;

diseases associated with high temperature.

It should be remembered that green tea increases the acidity of gastric juice, which is undesirable for stomach and duodenal ulcers.

Those suffering from rheumatoid arthritis should also avoid this drink.

Exciting substances included in green tea - caffeine, theobromine and theophylline - actively affect the nervous and cardiovascular systems. Therefore, you should not get carried away with green tea, especially strong, for people suffering from tachycardia, increased excitability, and insomnia.

Remember that tea left for later increases the amount of purine compounds and caffeine. Such tea is especially dangerous for patients with hypertension, glaucoma and gout. Green tea is not recommended to drink on an empty stomach, as well as while drinking alcohol. Tea with alcohol forms aldehydes, which are bad for the kidneys.

AT paper bags green tea cannot be stored: they do not close tightly and allow moisture to pass through; with such storage, tea will deteriorate very soon.

Four simple rules for brewing fragrant green tea.

Rule one. Brew green tea in a warm teapot

A cold teapot will lower the temperature of the water by about 20 degrees. Therefore, the first green tea brew will be spoiled by the cooled water. Such tea will not bring any harm or benefit, and you will not get pleasure from drinking tea. Essential oils and trace elements will not have time to leave the tea leaf in full. Therefore, before brewing tea, warm the teapot by pouring boiling water over it.

Rule two. Do not boil green tea

Hot water destroys the beneficial components of tea and spoils its taste and aroma, and also reduces its beneficial properties. Optimum temperature brewing 60-80 degrees Celsius. Certain types of tea need to be brewed more hot water. The brewing temperature is usually indicated on tea packages (if you buy it from a reliable manufacturer). It is better to use spring water, and if not possible, then soft and light (no smell, taste or taste in the mouth).

If you want to drink real healing drink- Don't let the water boil! It is enough to heat it up to 95 degrees (water bubbles begin to appear at the bottom of the kettle), and then cool it. In boiling water, all salts precipitate, and oxygen leaves the water - so the tea will no longer be so tasty and fragrant.

Rule three. The first water must be drained

The Chinese at tea ceremonies always drain the first water poured into the teapot. This is done in order to rinse the tea. After that, the tea leaves are immediately filled with fresh water.

Rule four. Control your green tea brewing time

Do not steep green tea for too long. If you overexpose it in a teapot, it will be bitter, as a lot of tannins will be pulled out of the leaf. In addition, such tea cannot be brewed several times, because all the flavor has already been used. Please note that each type of tea has its own brewing time. It can vary from 30 seconds to 1 minute.

And yet, you should not focus on the color of green tea. Each variety of green tea has its own color. Some varieties are almost transparent, others are light green, or honey, amber.

Advice: Never drink cold green tea.

Cooled tea loses many of its beneficial properties: vitamins are lost, essential oils evaporate, antioxidants are destroyed. Always make only as much tea as you can drink.

The aroma and taste of tea depends not only on the correct brewing, but also on the conditions of its storage. Equally important is the dishes in which you brew the drink.

Brew tea in pottery

Clay - perfect option for the teapot. It has excellent heat capacity, is chemically neutral and allows the tea leaves to "breathe" - i.e. created ideal conditions for brewing tea.

In addition to clay, you can use glass and porcelain, they are also chemically neutral. But tea leaves do not breathe in them. In addition, tea cools down very quickly in them.

Never brew green tea in metal or plastic teapots. In the first case, your tea will acquire a persistent taste of metal, and in the second, it will be saturated with toxic elements. Plastic is strictly contraindicated for hot products.

Store green tea properly

Delicate green tea leaves absorb odors and moisture well. If you store tea incorrectly, it will quickly lose its beneficial properties and aroma. Your tea will smell like anything but real green tea. Light can also ruin tea leaves. Therefore, use airtight and opaque dishes for storage. Tin cans with a tight-fitting lid or wooden boxes are suitable.

You can not store tea in paper bags either: they allow moisture to pass through and do not close tightly - the aroma of tea will disappear over time.

Green tea is recognized as the first of 10 foods that promote health and longevity. Minimal processing of this type of tea preserves most of the vitamins, minerals and other bioactive substances that affect all organs and systems of the human body.

The ability of tea to strengthen immunity, relieve spasms of cerebral vessels, activate the work of the heart, improve sleep, strengthen the nervous system, relieve depression, increase sexual energy and fight with overweight. The mechanisms of the anti-cancer and anti-radiation effects of tea still remain unexplored, but the benefits of tea in these cases are undeniable. The tea may help prevent cancer by purifying the blood and boosting the immune system. The anti-radiation effect of green tea is eloquently evidenced by the fact that the inhabitants of Hiroshima, who regularly drink several cups of green tea a day, not only survived after the explosion, but also improved their condition. Japanese green tea has the ability to absorb and remove strontium-90 from the body, even if it has managed to be deposited in bone tissue. By the way, modern man, surrounded by radiation from a computer, TV and other devices and inhaling the city air, it is simply necessary to regularly consume green tea, which has such valuable properties.

In addition to normalizing the functioning of the body, green tea is also a powerful spiritual stimulant. That is why green tea and oolong are used in Chinese and Japanese tea ceremonies. During the ceremony, tea promotes maximum focus and openness to new ideas. It is not uncommon for an understanding of a problem and a completely non-standard solution to it to come over a cup of tea. High-quality tea is a mild psychostimulant that regulates mental processes without causing harm to the body. With regular consumption of green tea, vision becomes sharper and the susceptibility of the nervous system increases, the reaction rate increases, the process of thinking accelerates, the ability to concentrate for a long time increases and creative activity is stimulated.

Tea makes us resilient to stress and improves mood in depression. All this can also be explained by the purification of blood from toxins, but it is much more pleasant to realize that together with tea we are pouring a mysterious, magical essence into ourselves. Tea connoisseurs note that conversations over tea differ from everyday conversations and reveal the interlocutor with better side. However, such remarkable properties possesses only fresh and properly prepared tea.

Despite the fact that tea packages indicate a shelf life of one to three years, three-year-old tea is much inferior in taste and useful properties to fresh tea. When buying tea, you should make it a rule to look at the date of production. The information on the packaging will help to avoid another trouble - flavorings. The very fact that “nature identical flavors” had to be added to green tea makes one wonder about its quality (or age). Even if the tea contains additives such as jasmine, hibiscus, chrysanthemum, pieces of fruit, lemon peel and other beautiful things, it is better to check the information on the package. Perhaps these additives only cover the use of flavorings.

It should not be assumed that green tea is a new and unusual product for Russia. Green tea was popular in Russia long before Europe knew about it. Only in the 19th century, following the English fashion, Russians massively switched to black tea. The love for black tea and the established traditions of its preparation "in Russian" often make it difficult to realize the fact that black tea is made from the same tea leaves as green tea, but it passes additional processing which makes it less useful.

The most common mistake when brewing green tea is using the “traditional Russian method”, in which the tea leaves are prepared in advance in a large teapot, infused for a long time, diluted with boiling water to taste and flavored with sugar. It is difficult to spoil the taste of black tea with improper preparation, so this economical method seems to many to be the only correct one. Green tea is softer and richer. He requires special attention. It is not surprising that green tea has so few admirers in Russia - it is quite difficult to enjoy the bitter liquid of a cloudy yellow color with a pungent odor ... In addition, with this method of brewing, tea loses all useful properties and even acquires harmful ones. It is completely pointless to force yourself to drink improperly prepared tea in order to get rid of excess weight.

To enjoy green tea, you need soft water without foreign odors. In no case should water be brought to a boil, even when brewing black tea. Green tea is much thinner than black tea hot water destroy its taste, aroma and beneficial properties. 80-85С - ideal temperature water for green teas. It is best to infuse tea in a small clay teapot. It is difficult to make recommendations about the number of tea leaves and the time of infusion, because it depends on the type of tea and the time of harvest, the softness of the water and personal preference. To begin with, you can brew one teaspoon of tea per 100 ml of water, if the taste is not bright enough, in next time increase the dose.

The taste properties of each tea are determined empirically. It takes a lot of experience and special knowledge to properly prepare an unfamiliar tea the first time. The only thing to remember when preparing green tea is that its infusion time should not exceed 10 seconds. (Of course, you can follow the package directions and steep for 3-4 minutes, but who likes the result?) Many green teas become bitter even when steeped for 3-4 seconds. Dilution of tea with water negates its beneficial properties. Adding sugar equates tea to compote, which is not bad in itself, but makes no sense, especially if the tea is expensive. Quality teas withstand up to 15 repeated brewing. That is why the teapot should be small.

With all its advantages, tea also has contraindications: excessive sensitivity to caffeine and addiction to caffeine. Sensitivity to caffeine can be individual, which is very rare, and situational: with exacerbation of stomach ulcers, hypertension, kidney disease, glaucoma, psychasthenia, and any illness accompanied by high fever. If you have a cold, you should drink weak green tea. Green tea is not recommended for pregnant and lactating women. large quantities, but a few cups of high-quality tea a day will do the trick. Young children are very sensitive to tea. Until 10-12 years old, children should not get involved strong tea, but a weak infusion of green tea will provide children's body vitamins and other useful substances.

Green tea gives wisdom healing action per person, strengthens male potency and quenches thirst.

Few people know that the tea plant has a second name Camellia sinensis. It is this beautiful literary flower that is directly related to one of the most popular drinks in the world.

Green tea lovers are well aware that its difference from black, red and white lies in the conditions of collection and in technological features production. Differences in processing allow you to activate the beneficial microelements of the tea leaf in different composition and to varying degrees, it is known to contain tannins, flavonoids, theanines, caffeine, various minerals, strong antioxidants such as polyphenols and others useful material and vitamins. There is a good comparison of green tea with a chemical laboratory, in which some of the reagents have not yet been deciphered. Moreover, the chemical composition of tea changes under the influence of many factors during growth, processing, and preparation. Transformations are constantly taking place, which is why there are no trifles in the selection and brewing of tea, every detail makes sense if it is important to achieve the desired result.

People with normal blood pressure should also not abuse the artificial management of their physical and nervous activity.

The cause of complications may be polyphenols, antioxidants, which, along with undeniable benefits for the body, they also have their negative sides, in excess they lead to violations of the liver and kidneys, which do not have time to process them and remove them from the body.
