Diosmin and Hesperidin is a phlebotonic drug and a vascular protecting agent. It reinforces venous tone by prolonging the activity of parietal noradrenaline. Thus Diosmin and Hesperidin decreases venous capacitance, venous distensibility, and venous emptying time.? Diosmin and Hesperidin protects the microcirculation by fighting the microcirculation damaging process; It combats venous inflammation by decreasing leukocyte activation, and as a consequence, by inhibiting the release of inflammatory mediators, principally free radicals and prostaglandin. Thus Diosmin and Hesperidin normalizes capillary permeability and strengthens capillary resistance. Diosmin and Hesperidin acts on the lymphatic system, It improves lymphatic drainage by increasing lymph flow and lymph oncotic pressure.
