Natural Help for High Blood Pressure
Two clinical trials indicate that stevia's stevioside compounds could help treat patients with high blood pressure. Statistically significant results showed stevioside was comparable to hypertension medications, but without the potentially negative side effects of these drugs:(33, 35, 76)
Type of Study | Dosage | # and Type of Participants | Results |
---|---|---|---|
1-year randomized, placebo-controlled, multicenter clinical trial(33)
|
250 mg stevioside 3 times/day | 106 Chinese patients with hypertension |
Blood pressure began to decrease in a week, with significant reduction by 3 months. The beneficial effects of the stevia compound were sustained over the course of the trial:
|
2-year randomized, placebo-controlled clinical trial(35)
|
500 mg stevioside 3 times/day | 174 Chinese patients with hypertension |
Significant reduction in blood pressure by 3 months that was sustained over the course of the trial:
|
Randomized, placebo-controlled, crossover, double-blinded clinical trial(76)
Blood tests and blood pressure measurements were taken at ingestion and then at 60, 120, and 240 minutes afterwards. |
4 grams of whole stevia leaf sweetener (or 10 grams of sugar in control group) mixed in green tea | 113 patients with type-2 diabetes; some with hypertension | 11.5% decrease in blood pressure in patients who had high blood pressure. |
