Quercetin is one of the flavonoids groups. It is in fact a flavonol.
Functions of flavonoids in plants
Flavonoids are widely distributed in plants fulfilling many functions.
Flavonoids are the most important plant pigments for flower coloration producing yellow or red/blue pigmentation in petals designed to attract pollinator animals.
In higher plants, Flavonoids are involved in UV filtration, symbiotic nitrogen fixation and floral pigmentation.
They may perform as a chemical messenger or physiological gauge and can also act as cell cycle inhibitors.
Flavonoids secreted by the root of their host plant help Rhizobia in the infection stage of their symbiotic relationship with legumes like peas, beans, clover, and soy.
Rhizobia living in soil are able to sense the flavonoids and this triggers the secretion of Nod factors, which in turn are recognized by the host plant and can lead to root hair deformation and several cellular responses such as ion fluxes and the formation of a root nodule.
In fact, some flavonoids have inhibitory activity against organisms that cause plant disease e.g. Fusarium oxysporum.
It is found in apples, onions, tea, red grapes, leafy green vegetables, citrus fruits, broccoli, cherries, raspberries, prickly pear cactus, and some varieties of honey.
Especially, those made from the Eucalyptus flower.
Quercetin is a very active form of flavonoid.

It is also found in many fruits, vegetables, and herbs.
Quercetin is anti inflammatory, which helps to promote healing and boosts the body's immune system.
It also helps in preventing certain ailments and diseases.
It slows down the release and manufacture of histamine, and as such, is good for the relief of allergies and insect bites.
It does this by blocking the secretion of histamine.
Quercetin is also anti inflammatory, and as such, can help with certain types of arthritis and prostate inflammation.
It increases the manufacture of fibronectin and collagen, which help to keep joints and skin in good condition.
It promotes the healing of wounds and abrasions and aids in repairing nerve damage.
Quercetin is a phytoestrogen which works like estrogen, and is helpful in inhibiting the growth of breast cancer.
It binds to estrogen receptors and stops the breast cancer cells from getting estrogen.
This will stop their growth.
Quercetin has also been found to be very useful in prevention of hardening of the arteries.
It prevents build up of macrophages.

Quercetin also strengthens capillaries helping with blood flow and circulation.
It is an antioxidant and in fact it is known to be one of the most powerful ones available today.
This means that it protects the body from free radicals.
The liver produces these free radicals as part of the metabolic process.
The free radicals can cause damage and aging to the body's cells.
Research is being done to possibly help with cancer, respiratory diseases, heart disease, and cataracts.
Research with Quercetin has shown that it helps to prevent cancer by preventing the flow of oxygen and nutrients to cells with cancer.
As you can see, Quercetin is a very powerful substance and has multiple uses in the body.
It can also be taken in the form of diet supplements.
These are available in health food stores or through distributors.
It is very wise to consult with your doctor before you take any diet supplements.
Although natural products like Quercetin, rarely have side effects.
