Diosmin is a type of plant chemical found mainly in citrus fruits. People use diosmin to make medicine.
Diosmin is used for treating various disorders of blood vessels including hemorrhoids, varicose veins, poor circulation in the legs (venous stasis), and bleeding (hemorrhage) in the eye or gums. It is also used to treat swelling of the arms (lymphedema) following breast cancer surgery, and to protect against liver toxicity. It is often taken in combination with hesperidin, another plant chemical.
Diosmin might help treat hemorrhoids by reducing swelling (inflammation), and restoring normal vein function.
