QUERCETIN
Articles by a Naturopathic Doctor ( N.D.)

Quercetin is best known for the ability to repair and restore damaged cells such as bruises, wound healing and lessen herpes outbreaks ...

quercEtin

A natural source of Quercetin can be found in the skin of citrus fruits
Bioflavinoids are essential for the absorption of vitamin C.  The body cannot produce them; rather they must be taken in through the diet.  They are called vitamin P because they regulate the Permeability of vessels and increase vessel strength.  They are used to treat injuries because they repair damaged capillaries, which allows the body to restore proper blood flow to the area.  Thus pain is relieved and bruising is minimized.  They work with vitamin C to kill bacteria, increase circulation, stimulate bile flow, lower cholesterol, prevent cataracts and prevent herpes outbreaks.

There are many different types of bioflavinoids.  Most bioflavinoid complexes contain some of the following bioflavinoids, citrin, flavones, hesperidin, quercetin and rutin.  Rutin and hesperidin are bioflavinoids that are well studied for their effect on the vascular system.  They can be used for minimizing bruising or treating conditions such as hemorrhoids or varicose veins because all of these conditions occur due to compromised veins and capillaries.  Quercetin is a bioflavinoid that acts as an antioxidant, antihistamine and anti-inflammatory, in addition to its vascular effects.  It stabilizes the membranes of mast cells.  Mast cells release histamine when they come into contact with an allergen so that the body mounts an immune response.  It is this immune response that is responsible for allergic symptoms such as runny nose and itchy watery eyes.

Cooking, heat, light, oxygen and pollutants, like cigarette smoke, destroy bioflavinoids.
