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.

How does it work?

Black tea contains 2% to 4% caffeine, which affects thinking and alertness, increases urine output, and may reduce the symptoms of Parkinson's disease. It also contains antioxidants and other substances that might help protect the heart and blood vessels.

Mental alertness. Drinking black tea and other caffeinated beverages throughout the day helps to keep people alert, even after extended periods without sleep.

Insufficient Evidence for

Bladder cancer. Some early research suggests that people who drink black or green tea might have a lower risk of urinary tract cancers. However, other research shows that drinking black tea is not linked with a reduced risk of bladder cancer.

Heart disease. Some early research suggests that people who regularly drink black tea have a lower risk of developing heart disease. However, other research suggests that drinking black tea is linked with an increased risk of heart disease becoming worse or causing death.

Cavities. Early research suggests that rinsing with a black tea extract might prevent cavities.

Kidney cancer. Early research suggests that people who drink more black or green tea have a higher risk of developing kidney cancer.

Lung cancer. Green tea and black tea contain chemicals called phytoestrogens. Some research shows that men who get more phytoestrogens in their diet have a lower risk of developing lung cancer than men who do not get these chemicals. However other early research suggests that drinking black tea is not linked with a reduced risk of lung cancer and may even be linked with an increased risk.

Mouth cancer. Early research shows that black tea might help prevent mouth cancer in patients with lesions in the mouth that may turn into cancer.

Pancreatic cancer. Some early research suggests that drinking black tea is linked with a reduced risk of pancreatic cancer risk. However, other research shows conflicting results.

Prostate cancer. Early evidence suggests that drinking black tea is linked with a reduced risk of prostate cancer.

Stress. Early research suggests that drinking black tea for 6 weeks does not improve blood pressure, heart rate, or feelings of stress ratings while performing stressful tasks.

Stroke. Black tea contains chemicals called flavonoids. Early research suggests that eating a diet that contains flavonoids is linked with a lower risk of stroke.

Weight loss. Early research suggests that taking a combination product containing black tea extract plus green tea extract, asparagus, guarana, kidney bean, and mate along with a combination of kidney bean pods, garcinia, and chromium yeast for 12 weeks does not reduce body weight in overweight adults.

Stomach disorders.

Vomiting.

Diarrhea.

Headache.

Other conditions.

More evidence is needed to rate the effectiveness of black tea for these uses.
