Flavonoid
Chemically, the flavonoid compounds contain in their structure two phenyl rings and a heterocyclic ring. In plants, they are the important pigments (in Latin “flavus” means yellow). The different flavonoids have diverse biological functions including: protection against ultraviolet (UV) radiation and phytopathogens, signaling function, auxin transport, as well as the coloration of flowers as a visual signal that attracts pollinators.Flavonoids are found to be powerful antioxidants and have potentially the anti-inflammatory, anti-allergic and anti-cancer properties. Besides, they may have beneficial effects on cardiovascular diseases. They help to reduce blood pressure in the arteries and so can relax blood vessels; they also improve blood circulation, which will keep the blood flowing and make it less likely to pool in the veins. All of which can reduce your propensity to varicose veins.
