Used primarily in the treatment of diabetic microangiopathy and chronic venous insufficiency. It helps reduce capillary permeability and fragility, thereby improving microcirculation. Commonly prescribed to alleviate symptoms of diabetic retinopathy, such as vision impairment and retinal hemorrhage, by protecting blood vessel walls and reducing leakage. Also applied in managing symptoms of hemorrhoids and varicose veins due to its effect on vascular integrity. Its anti-inflammatory and antioxidant properties support endothelial function and may slow progression of vascular complications in diabetes.
