500mg of pure quercetin per vegetable capsule for potent anti-histamine and anti-inflammatory actions.
  • 500mg of quercetin per vegetable capsule, naturally sourced from the flowers of the Sophora japonica plant
  • Indicated for mast cell stabilization and anti-histamine action in order to manage and treat allergic and inflammatory responses such as hay fever and non-bacterial prostatitis


Allergic rhinitis, more commonly referred to as “hay fever”, is the most common form of allergy and presents with inflammation in the nose and respiratory airway after exposure to an airborne allergen. Individuals with allergic rhinitis may experience a runny or stuffy nose, sneezing, itchy throat, watery eyes or headaches.

Other forms of allergies may present with skin rashes, itchiness, redness or digestive concerns. Regardless of whether the immune system is reacting to dust, cats, freshly cut grass, pollen or certain foods, the body is producing an excessive immune response, which consists of many pro-inflammatory chemicals. One of these chemicals is known as histamine and it is the chemical often responsible for the uncomfortable allergy symptoms.

Quercetin is a natural flavonoid compound that is most abundantly found in apples, onions, tea and berries. Clinically, quercetin is most well-known for its ability to stabilize mast cells, prevent histamine release, and prevent and manage allergic responses, including allergic rhinitis.

An additional benefit of quercetin is its cardioprotective nature through its ability to prevent the oxidation of LDL cholesterol. Finally, quercetin has also been shown to have gastroprotective, anti-cataract, anti-inflammatory and anti-viral effects. A combination of its immune modulating capabilities and these actions may explain

why research has found that it can be effective in cases of chronic nonbacterial prostatitis.

Cyto-Matrix’s Quercetin provides a high-dose of 500mg of pure quercetin in each vegetable capsule. Naturally sourced from the flowers of the Sophora japonica plant, Cyto-Matrix’s Quercetin is a sound choice for mast cell stabilization and anti-histamine action in order to manage and treat allergic and inflammatory responses such as hay fever and non-bacterial prostatitis.
