VENODIOL

Diosmin (diosmetin 7-O-rutinoside), a flavone derivative also known as venosmine, is a glycoside of diosmetin, which in turn is the 4'-methoxy derivative of luteolin. Diosmin prolongs the vasoconstrictor effect of norepinephrine on the vein wall, increasing venous tone, and therefore reducing venous capacitance, distensibility, and venous stasis. This increases the venous return and reduces venous hyperpressure present in patients suffering from CVI.

Ascorbic acid, coupled with dehydroascorbic acid to which it is reversibly oxidised, has a variety of functions in cellular oxidation processes. Ascorbic acid is required in several important hydroxylations, including the conversion of proline to hydroxyproline and appears to have an important role in metal ion metabolism, including the gastrointestinal absorption of iron and its transport between plasma and storage organs.
