The Brief Introduction of Black Tea Extract 

     Black tea is a product made from the Camellia sinesis plant. The aged leaves and stems are used to make medicine. Green tea, 

which is made from fresh leaves of the same plant, has some different properties.

    Black tea is used for improving mental alertness as well as learning, memory and information processing skills. It is also used for 

treating headache and low blood pressure; preventing heart disease, including “hardening of the arteries” (atherosclerosis) and heart 

attack; preventing Parkinson's disease; and reducing the risk of stomach and colon cancer, lung cancer, ovarian cancer, and breast 

cancer. It is also used for type 2 diabetes, stomach disorders, vomiting, diarrhea, and as a diuretic to increase urine flow. Some 

people use black tea for preventing tooth decay and kidney stones. In combination with various other products, black tea is used 

for weight loss.

    Hardening of the arteries (atherosclerosis). Early research shows that people who drink black tea seem to have a reduced risk of 

having their arteries become hardened. This link is stronger in women than men.


    Low blood pressure after eating (postprandial hypotension). Drinking beverages containing caffeine, such as black tea, helps 

increase blood pressure in older people who have low blood pressure after eating.


    Kidney stones. Women who drink black tea seem to have an 8% lower risk of developing kidney stones.


    Heart attacks. Some research shows that people who drink black tea have a lower risk of having a heart attack. Also, people 

who have been drinking black tea for at least a year before having a heart attack seem to be less likely to die after having a heart 



    Brittle bones (osteoporosis). Early research shows that older women who drink more black tea seem to have stronger bones. 

Drinking more black tea also seems to be linked with a lower risk of hip fracture in older men and women.

Ovarian cancer. Women who regularly drink tea, including black tea or green tea, appear to have a lower risk of developing ovarian

cancer compared to women who never or rarely drink tea.


    Parkinson's disease. Some research shows that people who drink caffeinated beverages such as coffee, tea, and cola have a 

lower risk of Parkinson's disease. The lower risk seems to be directly related to the dose of caffeine in men but not women. Drinking

black tea also appears to be linked with a reduced risk of Parkinson's disease among people who smoke cigarettes.
