It's a randomized, and single-blind trial and was designed to evaluate the effects of MGFs (MGF-4 and MGF-4) on blood pressure. 50 participants with hypertension (systolic blood pressure between 130-179 mmHg or diastolic blood pressure between 85-109 mmHg) who did not accept any hypertension medication were randomized allocated to either MGF-4 or MGF-7 group. Participants were instructed to take 4 capsules of MGF-4 or MGF-7 daily throughout the duration of the 8 weeks intervention study. After treatment, the change of the blood pressure and relative mechanism were analyzed.
The aim of this study is to investigate the antihypertensive effects of Mei-Gin formula-4 (MGF-4) and Mei-Gin formula-7.
