Overview

Randomized clinical trial shows olive leaf extract lowers blood pressure in hypertensive patients, indicating significant health benefits.

Key Points

  • Olive leaf extract significantly reduced 24-hour systolic blood pressure compared to baseline and placebo.
  • In the olive leaf extract group, diastolic blood pressure load decreased from 30.7% to 21.2% over 12 weeks, while the placebo group showed no significant change.
  • This multicenter randomized, double-blind trial included 621 participants and assessed various blood pressure metrics and metabolic parameters.
  • The findings highlight the potential of olive leaf extract to improve blood pressure control and metabolic health in hypertensive individuals.
