In addition to all the useful effects of tea on the human body, there are also harmful effects that manifest at the wrong approach to this beverage. In Chinese tea culture is the view of the harmfulness of tea and put it in "tea Ten prohibitions."
The prohibition of the first – tea on an empty stomach.
When you drink strong tea on an empty stomach, cold nature of the tea, penetrating inside, can cool the spleen and stomach, similar to the "penetration of a wolf in the house", in China since ancient times advised "not to drink tea on an empty heart."
Ban second – scalding hot tea.
Too hot tea irritates the throat, esophagus and stomach. Long-term consumption of very hot tea can lead to painful changes of these organs. According to foreign studies, frequent consumption of tea with a temperature above 62 degrees leads to increased vulnerability of the walls of the stomach and gives the symptoms of the various diseases of the stomach. The temperature of the tea should not exceed 56 degrees.
The third prohibition – on a cold tea.
At that time, as warm and hot tea give courage, a clear mind and vision, iced tea gives side effects: stagnation of cold and accumulation of phlegm.
The prohibition of the fourth on too strong tea.
The high content of caffeine and tannin in strong tea can cause headache and insomnia.
Ban fifth – for brewing tea.
If brewing tea too long, tea polyphenols and essential oils begin to spontaneously oxidize, which not only deprives the tea of transparency, taste and aroma, but also significantly reduces the nutritional value of tea due to the oxidation of contained in tea leaves of vitamins C and e, amino acids and other valuable substances. In addition, Nativas, tea is exposed to the environment, if the tea for a long time languishing in the warmth it significantly increases the content of microorganisms (bacteria and fungi).
Ban sixth to multiple steepings.
Usually after the third or fourth welding in tea leaves there is little that remains. Experiments show that the first infusion draws approximately 50% of the nutrients from the tea leaves, the second – 30%, and the third only about 10%, the fourth welding adds another 1-3%. If you continue to brew tea on, then the infusion may go and harmful ingredients as harmful elements contained in very small quantities in tea leaves, leave in infusion in the least.
Ban seventh – tea before meals.

The prohibition of the eighth – tea immediately after a meal.
Any drinking liquids immediately after eating leads to a significant decrease in the concentration of gastric juice, and this slows down the digestion and disrupts the work of all organs of digestion. If you want to drink tea after a meal, wait 20-30 minutes.
The prohibition of ninth – zapivanie tea drugs.
Tannins contained in tea, laminating, form tannin, from which many drugs produce a precipitate and poorly absorbed. Therefore, the Chinese say that tea destroys medicines.
Ban tenth on yesterday's tea.
Tea, the constant day, not only loses its vitamins, but also becomes the perfect breeding ground for bacteria. But if the tea is not spoiled, it can be used for medicinal purposes, but only as an external agent. So, for the present day tea is rich in acids and fluorine that prevent the capillaries from bleeding, so yesterday's tea helps with inflammation of the mouth, pain in tongue, eczema, bleeding gums, superficial skin lesions, ulcers. Rinsing yesterday's tea helps to reduce discomfort in the manifestation of proteins in the blood vessels and after tears and mouth rinse in the morning before brushing teeth and after meals not only leaves you feeling fresh, but also strengthens the teeth.
