Diosmin (DSM)

Diosmin is 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.

Diosmin has been found to be effective in mitigating hyperglycemia in diabetic rats. It is also speculated that diosmin might have potential in the treatment of neurodegenerative diseases, such as Alzheimer's disease, and its anti-inflammatory and anti-apoptotic activity has been demonstrated in neuronal cells, in vitro.
