Allergies? Cataracts? Parkinsons? Gout?.....What is Quercetin?


FABA BEAN LEAF: 

Viscia faba is a member of the vetch family and has been cultivated for centuries. All parts of the faba plant are edible, and its seeds have been a staple of human nutrition. Many cultures have enjoyed the leaves of the faba plant, preparing them similarly to spinach.

As is the case with barley, when the faba plant begins its reproductive cycle, the young plant is at the peak of its nutrition. The nutritional composition of the leaf is different from the actual bean. During this early stage, the plant has an abundance of certain flavonoids. Quercetin, found in the faba bean, field pea, and spinach leaves, belongs to a group of plant pigments, flavonoids, that are partly responsible for the color of many fruits and vegetables. Unlike the synthetic form of quercetin dihydrate found in most supplements, the quercetin found in AIM LeafGreens occurs naturally in the leaves. This is important because synthetic quercetin dihydrate is not soluble in water. Thus consumption of this synthetic compound provides no meaningful benefits. The natural quercetin found in AIM LeafGreens is more bioavailable and absorbable.

The flavonoid quercetin offers a variety of potential therapeutic uses and benefits. Recent research studies have found quercetin to inhibit the production and release of histamine and other allergic and inflammatory substances. Histamine contributes to allergy symptoms such as runny noses, water eyes, and the swelling of soft tissue.

Quercetin can also inhibit the aggregation of platelets (abnormal clotting), fibrin, and other blood components that cause obstruction of blood vessels. This flavonoid binds selectively to platelet aggregation on blood vessel walls and restores the natural compound prostacylin, a vasodilator (opens blood vessels). In other words, quercetin has an anti-clotting function that may help improve circulation.

The anti-imflammatory properties of quercetin have been researched extensively. In one study, quercetin inhibited the inflammation in joints for those with arthritis. There have been several reports of people with rheumatoid arthritis and fibromyalgia who have increased their flavonoid intakes and experienced symptom relief.

Blindness or the loss of vision can result from untreated cataracts. Patients with cataracts have been found to have very high levels of hydrogen peroxide in the aqueous humor of their eye. In a recent study it was discovered that when quercetin enters the eye it binds with a naturally occurring enzyme in the lens. This newly formed metabolite protects the lens from opacification (becoming cloudy) and oxidative damage from high levels of hydrogen peroxide.

Quercetin is also involved in the reduced production of uric acid. This occurs when the flavonoid inhibits the xanthine oxidase, which can ease gout symptoms.

Dopamine is a hormone and neurotransmitter in the human body and L-Dopa, which is found in faba bean plants, is its chemical precursor. Both compounds are precursors to the well-known neurotransmitters, norepinephrine and epinephrine.

L-Dopa is helpful in the treatment of Parkinson's disease, because it can cross the blood-brain barrier whereas dopamine cannot. It is supplemented in the diet to increase libido and human growth hormone, and combines with tyrosine to produce the natural pigment in our skin, melanin.



AIM LeafGreens Ingredients: Barley leaf juice concentrate, faba bean leaf juice concentrate, field pea leaf juice concentrate, spinach leaf juice concentrate, rice lecithin, xanthan gum, natural citrus flavor.

Taste: Leaf Greens has an exceptional taste for a green juice powder. For those who want a really good tasting drink try this. Mix 1 teaspoon Leaf Greens to 1 tablespoon BarleyLife Xtra in about 8 ounces of cool water. For smaller drinks or for those who are just starting out try 1/4th teaspoon of Leaf Greens to 1 teaspoon of BarleyLife Xtra. It is delicious!

Use: Can be mixed in water or fruit juice (other than cranberry or prune juices). A teaspoon once or twice a day may be all it takes to experience benefits. Some may need to start with smaller amounts as too much initially can result in detox symptoms. Some mix a small amount each day with their BarleyLife (and Just Carrots and Redibeets) while others use in place of BarleyLife.
