Red tea doesn’t lower blood pressure
Cochrane reviewed the effect of roselle (Hibiscus sabdariffa) on blood pressure in hypertensive adults.
First, the details.
- No studies were worth reviewing.
And, the results.
- In the absence of studies to review, there was no evidence to support drinking red tea to lower blood pressure.
The bottom line?
More than 10 years ago there was a study in rats where roselle given by injection lowered blood pressure.
But nothing in humans.
