1.Diossmine enhances venous wall tension, even at high temperatures, and causes venous contraction more strongly than other drugs such as rutin, which can still enhance venous tension in the body during acidosis. Diosmin has a specific affinity for veins without affecting the arterial system. 2. Improving microcirculation Diosmin can significantly reduce the adhesion, migration, disaggregation and release of inflammatory substances such as histamine, bradykinin, complement, leukotrienes, prostaglandins and excessive free radicals between white blood cells and vascular endothelial cells, thereby reducing capillary permeability and enhancing its tension. Diosmin also has the function of reducing blood viscosity and enhancing the flow rate of red blood cells. Thus reducing microcirculation stasis. 3. Promoting lymphatic reflux diossmine increases the speed of lymphatic drainage
