Quercetin is known for inhibiting allergy and inflammatory responses. Allergy and inflammatory conditions are triggered by contact with allergens that are absorbed into the blood. When allergens meet special immune cells containing histamine, the cell wall of the immune cell becomes leaky and releases histamine into the surrounding blood and tissues. Allergen released histamine produces the familiar allergic symptoms of runny noses, blocked sinuses, itchy eyes, blotchy skin, coughing and wheezing.
Quercetin actually helps to stabilize the cell walls of the immune components that contain histamine. This stabilization helps prevent release of histamine. The allergy symptoms simply will not occur without release of histamine, even though you have inhaled pollen, animal hair, or whatever normally triggers allergy attacks.
Quercetin also helps with asthma, which is allergic inflammation involving the lungs.
Quercetin is available in supplement form. Quercetin is usually combined with bromelain or pineapple enzyme since it is barely soluble in water and needs the bromelain to increase absorption. Bromelain has powerful anti-inflammatory properties that act synergistically with quercetin.
