In 1650, the Dutch merchantmen the Chinese black tea for the first
time will introduce Europe. 17th century, an English Elizabeth empress
th establishment East India company, directly from Fujian import tea.
Because Xiamen purchases the military black tea dark brown thick
is deep, therefore is called Black Tea.
2、Red tea introduction:
The tea according to picks the spot to be different, but has by the inferior several kind of different names: 1. flowered o.ps (Flowery
Orange Pekoe) 2. o.ps (Orange Pekoe) 3. pekoes (Pekoe) generally
speaking, the tea tree peak spot tea, belongs to a more superior tea,
the spot tea, the quality relative is downward worse.
The black tea, the green tea and the Chinese tea difference is
ferments the degree difference in the manufacture process. Black tea may divide into two big kinds, a kind is the linearity black tea,
another kind is the garrulous shape black tea. The linearity black tea
process picks, the collection, rubs twists, the fading, the fermentation, , classifies seven main stages to make. The
garrulous shape black tea is the process picks, the collection, the fading, C T C (cuts, rips, rubs), the fermentation, , classifies seven main stages to make.
二、Black tea value：
Vitamin C: Prevents the scurvy, the enhancement resistivity, assists
effect of the anti- cancer; grams teas contain
milligrams vitamins C.
In the tea contains vitamin A, D, E, K, B1, B2,
B6, H, C, P.
The excited central nervous system, promotes
the thought, rouses the spirit, but also has the diuresis, sobers up,
enhances the gastric juice secretion, whets the appetite.
tea polyphenol: The enhancement blood capillary function,
prevented the vitamin C oxidation, the disintoxicating, prevents the
arteriosclerosis, antibacterial sterilization healthy health care
aspect:The black tea may help the stomach and intestines digestion,
the promotion appetite, but diuresis, elimination dropsy, and strong
Prevention disease aspect: The black tea antibacterial strength is
strong, rinses mouth with the black tea to be possible to guard
against the cold which the filterable virus causes, and the prevention
dental cavity and food poisoning, reduce the blood sugar value and the
三、 Black tea to research skin：
The black tea richly contains the oxidation inhibitor polyphenols
matter, therefore, beneficial skin health. But each women all want to
have the health the skin, but sun, earth's attraction, free radical
injury and diet not when all can cause the health, the young skin to
receive the injury. Includes the tension protein (in human body flesh
elastic tissue's protein) to interweave with the collogen only then
can enable the skin to have the tensity, the elasticity and is smooth.
Frequent also the insolation exposes to the sun under the sunlight is
for a long time the skin shifts to an earlier time senile and appears
the wrinkle the main reason, because in sun's ultraviolet ray may
cause in the skin to produce the harm tender skin dangerous material -
free radical, the free radical can make a sneak attack the collogen to
cause the appearance to be senile. Guards against exposes to the sun the product certainly indispensable,
but the oxidation inhibitor supplement can the effective addition
protection skin avoid the free radical and guard against the
ultraviolet ray injury.
In in the black tea oxidation inhibitor polyphenols matter, EGCg and
EGCg to reduce the destruction collogen collogen activeness to have
the strongest function. Once collogen activeness reduces, then is
helpful to increases the health collogen and enable the elastin to
tend to the integrity. On the other hand, EGCg and the ECGg foot causes
these proteins the again combination to cause the skin to look like
young. Therefore includes the oxidation inhibitor tea polyphenols the
nutrition supplement, has slows down because gets older causes the
function which the skin harms
In addition, the anti- oxidation is the present scientific circles
thought the free radical and the human body majority of diseases all
have close relationship, when the human body sound outside pollution
environment or the daily life diet, the pressure and so on cause in
vivo massively produces "an aggressive free radical", if in this time
body resists the free radical the matter to lack, then the human body
can cause many damage, but in the green tea ingredient the polyphenols
are the very strong oxidation inhibitor, may block a succession of
oxidizing reaction, avoids DNA and the cell oxidation. But these
oxidation can urge the cancer, the artery gruel shape scierosis, the
inflammation to respond and to get older occurrence. Moreover pointed
out after the research; The black tea polyphenols anti- oxidation
compares vitamin C to be stronger.
This is the anti- oxidized research which compares for the first time
carries on, compares the protection ability which EGCg and vitamin E,
C, the red wine and all that teas plants. Discovered research by in
the equivalent expression that, vitamin E to has suffered injury the
protection ability which the cell grows compared to richly to contain
EGCg the green tea extract essence important duty many,
but vitamin C the protective function which appears under the same density also low
very many, specially what is worth mentioning in the green tea extract
essence the EGCg cell protective function must compared to vitamin C
function strong nearly 80 times, compared to vitamin E function strong
10 times, with red wine in anti- oxide compound be stronger than
nearly 2 times.

四、 Black tea conclusion：
The black tea uses for the speech which drinks, may help the stomach
and intestines digestion to the human body, the diuresis, the
elimination dropsy and the strengthened heart function.
But black tea because contains the anti- oxidized member, for example: Son caffeine, tannic acid, amino acid, vitamin C, brass class compound, therefore,
the black tea extract fluid application has anti- aged above
cosmetology the effect. Moreover the black tea extract fluid
also includes the caffeine ingredient, therefore also may improve the
flesh the rough question, makes it to restore the tension health.
Therefore, the black tea extract fluid with the application in the
cosmetology maintenance, regarding likes to look good woman, but a big
