Varietes of tea:
All the varieties of tea derive from two: the one that comes from the Chinese species Camellia sinensis sinensis and the variety that comes from the Hindu state of Assam, Camellia sinensis assamica. From these it is produced what is known as black tea and green tea. The first one ressults from the fermentation of the leaf, while in the second type of tea the process of fermentation is stopped by means of the heat that destroys the oxidizing enzyme,so the resulting product possesses some unequal characteristics in its composition, flavor, scent and aspect. By not permitting the enzymes to act , the dry plant continues maintaining a green aspect, producing the green tea. In the black tea, oxidase enzyme acts on the polyphenols producing its oxidation and transforming them in compounds that present a brownish coloration .Both types of tea maintain the same stimulating, digestive and circulatory properties., but the anticancerous properties related with the green tea, and attibuted fundamentally to the polyphenols, are eliminated in the process of fermentation to what the black tea is subjected. This makes that, from a phytoterapeutic point of view, it becomes more advisable to use the green tea.
