Scientists conducted a study, revealing the positive effects of black tea on the cardiovascular system. According to experts, this drink effectively lowers blood pressure.

Scientists conducted a study, the results of which were published in the American Journal of Clinical Nutrition. A group of people was gathered to participate in the experience. They were asked to drink black tea three times a day, and as an alternative, another drink containing caffeine.

Specialists took measurements, recording blood pressure at the initial stage of the study. Then the indicators were taken two more times – after three and six months. At the same time, the scientists stated that a noticeable effect at the level of 10% was recorded at night, and the indicator was not so noticeable during the day.

However, after the scientists discovered that black tea reduces blood pressure indicators, they did not name the active substance, which leads to this effect. In their opinion, it is not caffeine, since it was contained in the control drink. In addition, they confirm the effect of tea on the circulatory system, but it needs to be verified with additional research.
