what is Citrus Aurantium Extract powder-Diosmin ?

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.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 aglycone is diosmetin.

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.


Diosmin prolongs the vasoconstrictor effect of norepinephrine on the vein wall, increasing venous tone, and therefore reducing venous capacitance, distensibility, and stasis. This increases the venous return and reduces venous hyperpressure present in patients suffering from CVI.

Diosmin improves lymphatic drainage by increasing the frequency and intensity of lymphatic contractions, and by increasing the total number of functional lymphatic capillaries. Furthermore, diosmin with hesperidine decreases the diameter of lymphatic capillaries and the intralymphatic pressure.

At the microcirculation level, diosmin reduces capillary hyperpermeability and increases capillary resistance by protecting the microcirculation from damaging processes.

Diosmin reduces the expression of endothelial adhesion molecules (ICAM1, VCAM1), and inhibits the adhesion, migration, and activation of leukocytes at the capillary level. This leads to a reduction in the release of inflammatory mediators, principally oxygen free radicals and prostaglandins (PGE2, PGF2a).

Health Benefits of Citrus Aurantium Extract powder-Diosmin 

Diosmin is a natural flavonoid that is extracted from various plant sources and sold as a daily supplement either by itself or combined with similar flavonoids. As a natural remedy, diosmin is not known to induce any negative side effects.

Circulation Benefits

Diosmin improves blood circulation and strengthens vein walls by improving the elasticity of blood vessels while inhibiting certain pro-inflammatory lipids.

Varicose Veins and Spider Veins
