Black Tea

It would be difficult to think that only efforts of Black tea sellers stimulated the Black tea recognition. The Black Tea success as a drink has been reached for its undisputable health values. Black tea consists, foremost, of vitamins, mineral and tannic acids, essential oils and caffeine.
As a matter of fact the presence of the last component has a lot to do with the Black Tea popularity. Therefore we have to talk a little more about caffeine. The caffeine possesses the energizing qualities and elevates working abilities. Even once Black Tea got the severe opposition in the form of coffee it stood firm, thanks to distinction in digestion of the caffeine containing in these two beverages.
In coffee the energizing action begins virtually immediately, but over the insignificant interval, after which tonic action sharply declines. And here in Black tea caffeine is digested slowly, but then stays longer time inside the body, keeping it in a functioning, robust condition. This tonic influences many systems of an organism, induces heart activity, favorably influences work of kidneys and promotes normal functioning of digestive system.
Naturally, Black Tea is used within the reasonable limits. That is, there is no misusing in Black tea leaves dosage, or in number of drinks, but try to use no more than 10 cups a day. By the way, in the companies where managers are watching closely the productive use of working hours, they have noticed that the coffee consumers spend more time to drink their favorite beverage, than devotees of afternoon Black tea. From the standpoint of influence of caffeine it’s quite an explainable. Once loaded, the lover of Black tea receives much longer power charge. Coffee quickly vaporizes, and the body demands the next dose of caffeine.
The secret of a Black Tea is that it’s simultaneously both tonics, and calms down. These contradictory at first glance properties dwell in the Black tea jointly, thanks to two components supplementing one another; the caffeine, and tannic acid. The tannin content in Black Tea is very high, about fifteen percent. The last one just possesses the properties to restrain the caffeine, therefore it has an ability to influence blood circulation and the central nervous system shows in Black tea more slowly, than with coffee, but stays longer. High doses of caffeine are toxic. So 1/3 oz, for instance, can be deadly to the human. But it is not necessary to be scared; to receive such dose in Black tea cup is almost impossible.
In the meantime caffeine works on an individual basis. Calm people and quiet people need the larger doses, active types need smaller doses. If you are irritated type, it’s better to drink Black tea with moderation, and in second part of the day not to drink in it at all.
During the digestion, the caffeine mixes with tannin, the caffeine generates then a pleasant taste without the bitterness, working in a human body softer, than pure caffeine. This mixture causes the loss of clarity of a Black tea drink at cooling down that is a sign of a high quality of Black tea. After heating, Black tea becomes clear once again. Unfortunately, average consumers accept it totally reverse, saying; this is an indicator of a low grade of the Black Tea .
