Quercetin is one of the most abundant antioxidants in the human diet, and it plays a vital part in fighting free radical damage.

“When health is absent, wisdom cannot reveal itself, art cannot become manifest, strength cannot exert, wealth is useless and reason is powerless”
Herophilies, 300BC

“A wise man should consider that health is the greatest of human blessings”

“There is only one good, knowledge, and one evil, ignorance.”

These statements should guide our actions, especially concerning our health. Very often we do not have the slightest idea of how to maintain good health. When all “building materials” are supplied to the cells and the damage is reparable, nature will do the healing.

Quercetin is a flavonoid found in foods including leafy greens, tomatoes, berries and broccoli. It is technically considered a “plant pigment”, which is why it is found in deeply coloured, nutrient-packed fruits and vegetables. Quercetin is one of the most abundant antioxidants in the human diet, and it plays a vital part in fighting free radical damage, as well as the effects of aging and inflammation.

According to the Department of Pathology and Diagnostics at the University of Verona in Italy, Quercetin and other flavonoids are anti-viral, anti-microbial, anti-inflammatory and anti-allergic agents, with the potential to be expressed positively in different cell types in both animals and humans. Flavonoid polyphenols are most beneficial for down regulating or suppressing inflammatory pathways and functions.

Quercetin is the most diffused and known nature-derived flavonoid there is, showing strong effects on immunity and inflammation caused by leukocytes and other intracellular signals.

It has been shown to inhibit leukotrienes, mast cells, and the release of histamine, which makes it a good candidate for anti-allergy therapy. Evidence also demonstrates that Quercetin blunts the inflammatory response of immune cells upon antigen recognition.

Quercetin has been shown to reduce histamine release in people with seasonal allergies by 96%.

Allergic signs and symptoms: Itchy stuffy and runny nose, post nasal drip, swollen lips, itchy throats, swollen red and itchy eyes, wheezing and coughing, difficulty breathing, asthma, rashes and hives, vomiting and diarrhea.

Food allergies: dermatitis, eczema, psoriasis, interstitial cystitis (recurrent urinary tract infections with a known cause), ulcerative colitis, Crohn’s disease, allergic rhinitis and bloating.

Most common allergies: food allergies (e.g. diary, wheat and gluten), drug allergies (e.g. Penicillin), insect bites/stings (e.g. bee sting), environmental (e.g. pollen, grasses and house dust mites).

Quercetin may assist with: cognitive impairment, gout, viral infections, cancer, skins disorders (including dermatitis), inflammation of prostrate, bladder and ovaries and stomach ulcers.

Food rich in Quercetin include: apples, peppers, red wine, dark cherries and berries, tomatoes, cruciferous vegetables including broccoli, cabbage and Brussels sprouts, leafy green vegetables including spinach and kale, as well as citrus fruits.

It is important to remember that nothing works in isolation. These nutrients may be used to assist or support Quercetin: L-Glutamine, probiotics, L-Methionine, Nettle, Bromelien and vitamin C.

Quercetin is contra-indicated for persons taking Warfarin, and its safety during pregnancy and breast-feeding has not yet been established.
