Drinking black tea has a good antihypertensive effect

Hypertension usually causes fatal consequences, but its symptoms are not obvious at the onset of the disease, so it is called the “silent killer.” According to a report by the US Medical Daily on April 4, a study published in the American Journal of Clinical Nutrition showed that drinking black tea can fundamentally reduce the rate of increase in blood pressure. Scientists are convinced that a component contained in black tea can have a positive effect on the rapid changes in blood pressure. At the same time, scientists found that black tea is more effective than white tea and green tea in lowering blood pressure because black tea is more oxidized and fermented longer.

To test the effects of black tea on blood pressure, the Australian research team selected 111 pre-hypertensive volunteers who were asked to drink 3 cups of black tea a day and measure blood pressure 3 times a day for 6 months. The results of the study showed that drinking 3 cups of black tea per day reduced the blood pressure of volunteers by about 10%. The beneficial effect of drinking black tea on blood pressure appeared after the first day and lasted for 6 months.

Therefore, experts recommend that high blood pressure patients drink 3 cups of black tea a day, while maintaining a healthy diet, avoid stress, and limit the intake of alcohol and salt.
