Black tea is made from the leaves of a bush called Camellia sinensis. A process called oxidation turns the leaves from green to a dark brownish-black color. Oxidation means the leaves are exposed to moist, oxygen-rich air. Tea manufacturers can control the amount of oxidation. Black tea is a fully oxidized tea. Green tea comes from the same plant, but is not oxidized. Many people drink black tea for alertness and energy. There is good scientific evidence to show this works. Black tea has a lot of caffeine. It also contains a little bit of a stimulating substance called theophylline. Both can speed up your heart rate and make you feel more alert. Black tea is also full of healthy substances called polyphenols. Polyphenols are antioxidants that can help protect your cells from DNA damage.
Black tea is known for its curative qualities and other health benefits. Some of them are as follows:
Asthma: Hot and brewed liquids, in general, bring relief to asthmatic conditions. In light of that fact, it is no surprise that black tea is extremely beneficial for asthmatic patients, as it expands the air passage, thereby allowing patients to breathe more easily.
Digestive Problems: Black tea is rich in abundant tannins and other chemicals that have a positive and relaxing effect on the digestive system of human body. This anti-inflammatory quality of black tea is also helpful for curing digestive disorders.
Breast Cancer: Drinking tea, either black or green varieties, aids women in preventing cancerous growth in the breasts, especially women in the pre-menopausal phase. Tea assists in raising the level of globulin hormones during the female menstrual cycle periods. The presence of theaflavins in black tea destroys abnormal cells in the body before they cause any major damage or change into cancerous cells. Thus, you can see that drinking black tea is equally beneficial for health as drinking green tea.
Heart Ailments: The regular consumption of black tea can help repair coronary artery dysfunctions in many heart patients. Therefore, black tea drinkers are at a decreased risk of contracting many cardiovascular diseases.
Diarrhea: Black tea has a healing effect on intestinal disorders due to the presence of tannins. It is advisable for all diarrhea patients to sip plain, black tea slowly for maximum benefits.
High Cholesterol: According to a study conducted by the American Heart Association in New Orleans, people who consume black tea can reduce their bad cholesterol levels, which are responsible for heart strokes and fatal attacks. It has also been found that people who drink 3 to 4 cups of black tea every day are at a lower risk for heart problems than those who consume minimal amounts or no tea at all.
