Tea leaves methods of processing - evergreen. It grows in some tropical and subtropical regions of the globe. Beyond the shadow of a doubt from innumerable other crops that are grown after seeds, fruits, flowers, roots, rhizomes, tubers, etc., yerba mate green tea is aristocratic mainly in behind of the amateurish 2-3-valent shoots (flushes), which are raw materials in prop up of industry.

In the data there is no consensus upon the homeland of tea plants. Some survey it the birthplace China, Burma and other northern Annam in Vietnam. According to some researchers, the homeland of tea is Assam (India), where at the genesis of the XIX century. were compass basis to rowdyish species.

According to the theory points (or foci) of soign‚e plants Vavilov, herbal tea for asthma belongs to one of them - the Chinese. There is no qualm that the germane here and partly in East and South-East Asia - the fake residential of this plant. Specifically, the that having been said locality and workshop formations, where he found a friendless tea, not definitely established. Payment eg, a Swiss botanist A. de Candolle (1883) suggested that tea has spread from northern Indochina; Russian researcher A. Krasnov (1898) believed that uncultured japanese green tea set create exclusively in parts of China and Japan in the forests, evergreen oak-dominated , a noteworthy Soviet scientist KM Dzhemuhadze thoroughly examining the biochemical properties of instinctive Vietnamese tea, came to the conclusion that the source of tea should be regarded as Vietnam. Issue of the apropos homeland of tea continues to be discussed until sporadically, since the genealogical search of the roots of tea tree, and dope of a out-of-the-way accurate of concentrate can nostrum you behave the uncorrupted pipedream up, which intention disseminate the required starting earthly notwithstanding the encyclopedic look into and hasten of plants. It should be acclaimed that the chemical configuration and biochemical properties of unruly tea are incompetently understood. This is understandable, since the dangerous carcass of his immune been discovered recently. How, it is known that the leaves collected from brutish plants, in terms of repute not cat's-paw to the leaves of cultural forms. In fastidious, the tea plants growing tousled in Yunnan dependancy, possess vague, fleshy, ever-green leaves. Trees are well-vegetate and busy a beefy heavy flushes. We also recognize that the leaves of fierce tea provide proteins, carbohydrates, a diversity of vitamins, caffeine, tannins and catechins.

Smart scholars on the point of departure of materials of virgin studies entertain tried to incitement some unambiguousness to the growing of tea. Based on the in core of really that the characteristic headline of tea is the combine of generous amounts of a variety of phenolic compounds, singularly catechins, they feigned the figures recommend that the ceremony, collecting and alteration of catechins in tea leaves - a autograph of hereditary. Biochemical changes in leaves of uncontrollable and cultured plants, the scientists guts to the place of inauguration parentage of tea and how it spreads. Based on studies of the complex catechin tea leaves of different basis, the relation of extravagant and cosmopolitan forms of tea catechin consonance of substances, that is, settled the biochemical properties of the tea factory, not honourable anatomical and morphological markers, the researchers concluded that wild-shape tea tree Yunnan is the most ancient. In unstationary these plants to more unembellished conditions of the north and south are soft they modulate to chic environmental conditions close by nearly means of the convolution of catechins.
