Malaysian medicinal plants were used traditionally for treatment of a wide range of diseases including diabetes, hypertension, inflammation and angiogenesis related diseases. This book was aimed to generate data and evidence about standardization of two Malaysia medicinal plants namely Ficus deltoidea (FD) and Orthosiphon stamineus (OS) for anti-hypertensive and anti-angiogenesic effects, since there is lack of sufficient scientific data in this regard.
