Highly recommended to people with chronic venous insufficiency (CVI) in lower limbs, the so called varicose veins. Its active substance - calcium dobesilate monohydrate (Calcii Dobesilas Monohydricum) - fortifies vein walls to prevent blood stasis when blood thickens and becomes sluggish leading to venous dilation, reduced elasticity and clotting. Rostil max decreases vascular permeability and fortifies blood vessels to prevent effusions and improve microcirculation. It also reduces vein oedema or dilation, thereby relieving pain and heaviness in legs due to poor circulation.
