About

This study assessed the antihypertensive effect of rosemary tea through a placebo-controlled clinical study, angiotensin-converting enzyme (ACE) inhibition analysis, and in silico evaluation of interactions between rosemary bioactive compounds and the AT1R (Angiotensin II Type 1 Receptor).

A randomized, double-blind, placebo-controlled trial was conducted in 54 male patients with mild hypertension. Participants were assigned to receive either rosemary infusion (n = 27) or placebo (n = 23) for 45 days. Ambulatory blood pressure monitoring wass used to evaluate blood pressure parameters. Serum ACE activity was measured at baseline and after the intervention using FAPGG hydrolysis. Molecular docking simulations were performed using the Dock 4.2 software.
