Reduced Systolic Blood Pressure

High evidence
Clinical

HS dose-dependently reduced systolic and diastolic BP compared to placebo and other teas. Although no significant differences were found between HS and antihypertensive drugs, HS showed moderate credibility for therapeutic BP reduction (> 10 mmHg), especially in individuals over 50 years, in trials lasting over four weeks, and in those with a low risk of bias.

Effect: Beneficial
Effect size: Moderate
Significant: Yes
