Rutin is a western drug whose efficacy and effects are mainly for capillary bleeding disorders with increased fragility, but also for the adjunctive treatment of hypertensive encephalopathy, cerebral hemorrhage, retinal hemorrhage, hemorrhagic purpura, acute hemorrhagic nephritis, recurrent rhinorrhea, traumatic pulmonary hemorrhage, and postpartum hemorrhage. Rutin is a genus of vitamin P, a glycoside of dehydroflavinone, which often coexists with vitamin C in food. Vitamin P is a hydrogen transmitter that can participate in oxidoreductase action in the body, can affect the activity of the thyroid gland, and protects adrenaline from oxidation. The main pharmacological effects are to maintain vascular elasticity, increase capillary resistance, reduce capillary fragility and permeability, and promote their cell proliferation and prevent blood cell clotting. In addition, pharmacological studies have found that rutin also has anti-inflammatory and anti-allergic effects.
