In a study from The University of Western Australia, scientists found drinking a cup of black tea three times a day may strongly reduce your blood pressure.
They discovered that black tea lowers systolic and diastolic blood pressure.
Blood pressure measurement consists of two numbers. The first is systolic and measures blood pressure when the heart beats, or contracts to push blood through the body.
The second number is diastolic and measures the amount of pressure in between beats when the heart is at rest.
High blood pressure could strongly increase people’s risk of heart disease.
There is already mounting evidence that tea is good for heart health, but this is an important discovery because it demonstrates a link between tea and a major risk factor for heart disease.
In the study, the team examined 95 Australian adults aged between 35 and 75 who were recruited to drink either three cups of black tea or a placebo with the same flavor and caffeine content, but not derived from tea.
After six months, the researchers found that compared with the placebo, participants who drank black tea had a lower 24-hour systolic and diastolic blood pressure of between 2 and 3 mmHg.
The team says more research is required to better understand how tea may reduce blood pressure, although earlier studies reported a link between tea drinking and the improved health of people’s blood vessels.

The study was conducted by Jonathan Hodgson et al and published in the Archives of Internal Medicine.
