Used in the treatment of chronic venous insufficiency, Diosimin helps improve venous tone and reduce venous capacitance. It is commonly prescribed for symptoms like leg heaviness, pain, and swelling associated with varicose veins. Also effective in managing hemorrhoids, it reduces inflammation, decreases bleeding, and alleviates discomfort during flare-ups. Its mechanism includes strengthening capillary walls, reducing capillary permeability, and exerting anti-inflammatory and antioxidant effects. Often included in phlebotonic formulations, it supports microcirculation and lymphatic drainage, making it beneficial in both venous and lymphatic disorders.
