Black tea remedy to reduce blood pressure
A new Australian study has shown that people who drank three cups of black tea a day reduced blood pressure by 2-3 points. Scientists say that even a small reduction in blood pressure can have a big impact on the prevalence of high blood pressure (hypertension) and easily decrease the risk of heart disease.
In the study, scientis from the University of Western Australia analyzed the effect of black tea on blood pressure in 95 men and women who regularly drank tea. Their mean systolic blood pressure ranged from 115 to 150.
Half of the participants drank three cups of black tea daily for six months, while the other half drank a placebo beverage with a similar taste and caffeine content. Both groups were similar with regard to gender, age and weight.
By the end of the study, those who drank black tea, there was a decrease in blood pressure by 2-3 points in the average systolic blood pressure and 2 points in the diastolic (bottom number in blood pressure readings).
The researchers say that there are several explanations for this phenomenon. Recent studies have shown that consumption of black tea improves the function of endothelial cells that line the inner surface of blood vessels. Endothelial dysfunction is an early indicator of changes in blood pressure.
According to other studies flavonoids in tea improves the tone of blood vessels, reduce the weight and the amount of abdominal fat.
Black tea is made from mature leaves of the tea bush plants. In fact, green tea is made from the same plant, but only from the fresh leaves. Antioxidants and other substances contained in tea, can help protect the heart and blood vessels. It is known that regular tea consumption reduces the risk of heart attack and atherosclerosis in women.
Black tea is also effective for improving mental alertness, reduce the risk of kidney stones, reducing the risk of developing Parkinson’s disease and the risk of ovarian cancer. In addition, black tea lowers stress levels of cortisol, which affects blood pressure and heart rate.
