The American Botanical Council has just recently published a report of a study conducted by The Yazd Diabetes Research Center in Yazd, Iran. The study shows that people with diabetes can benefit from drinking green tea or hibiscus daily.
In the study, 94 diabetics between the ages of 30 and 60 were randomly assigned to either a green tea drinking group or a hibiscus tea drinking group. Both groups were given similar samples of green tea and hibiscus tea to drink 3 times a day for 4 weeks.
The green tea drinking participants prepared the 3 gram tea sample in 150 mL of boiling water and steeped it for 5 minutes before drinking. The hibiscus drinking tea group prepared their tea under similar conditions, only steeping their tea for 10-15 minutes.
Each patient had their vital signs measured, including their systolic blood pressure and their diastolic blood pressure, before and after the study. After the study, blood pressure averages in the green tea drinking group decreased by over 39% in 4 weeks while the average blood pressure in the hibiscus drinking group decreased by 43%.
Attributing these blood pressure decreases to the polyphenol properties, the authors of the study have concluded that “mildly hypertensive type 2 diabetic individuals who drink three glasses of green or sour [hibiscus] tea daily for 4 weeks show significant decreased systolic and diastolic blood pressures."
The authors recommend that individuals with diabetes increase their green or hibiscus tea consumption to combat high blood pressure.
