Product Description
1. Sources and Habitation
Diosmin for Active Pharmaceutical Ingredients

Diosmin is a chemical found in citrus fruits and Scrophularia nodosa, it is also a semisynthetic drug (modified hesperidin), a member of the flavonoid family. 

It is an oral phlebotropic drug used in the treatment of venous disease, i.e., chronic venous insufficiency (CVI) and hemorrhoidal disease (HD), in acute or chronic hemorrhoids, in place of rubber-band ligation,  in combination with fiber supplement,  or as  an adjuvant therapy to hemorrhoidectomy, in order to reduce secondary bleeding. To control internal symptoms of hemorrhoids (piles), it is used with hesperidin. Clinical studies have been inconclusive and no review articles on its use in vascular disease have been published.

Diosmin is currently a prescription medication in some European countries, and is sold as a nutritional supplement in the United States and the rest of Europe.
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 livertoxicity. It is often taken in combination with hesperidin, another plantchechemical.
