Tea. This drink has been known to mankind for over five thousand years. Chinese emperors drank it. The Queen of England drinks it. You and I are also fans of this wonderful drink. Let’s take a look at its composition.
The first place in it is occupied by natural aromatic compositions. The second place is taken by tannin. The chemical composition of aromatic compositions depends on the place where the tea grows and the conditions for its collection and preparation.
As for the tannin, to which this article is devoted, its content depends not so much on the weather and climatic characteristics as on the age of the tea leaf itself. The older the leaf, the more tannin it contains.

General characteristics of tannins
What are tannins? Tannin, or gallobinic acid, is an astringent substance. The name comes from the French word “tanner”, which translated into Russian means tanning leather.
Tannins are found in tea and bird cherry, acorns and galangal rhizomes. It is thanks to tannins that wines made from dark grapes are very popular.
In addition, tannin is widely used as a tanning agent in leather goods. It is also used in the pharmaceutical industry in the manufacture of astringent anti-inflammatory drugs.
Daily requirement for tannin
Due to the fact that tannin performs a tanning function in our body, there is no data on its daily use. It should be borne in mind that the permissible amount of tannin used (in the composition of related compounds) depends on the individual characteristics of the organism.
The need for tannin increases:
With diseases of the gastrointestinal tract. Also, a solution of tannin in glycerin can be used to lubricate weeping wounds and ulcers for their quickest healing. In addition, tannin is used for mild diabetes mellitus and for the detection of pathogenic bacteria and viruses.
The need for tannin is reduced:
- in case of individual intolerance to tannin;
- with increased blood clotting.

Signs of excess and lack of tannin in the body
Due to the fact that tannins do not belong to the group of coordinating compounds, there were no signs of excess, as well as a deficiency. The use of tannin is, rather, associated with the episodic needs of the body in this substance.
