Quercetin

Benefits:

Less likely to cause urinary/stomach distress than many of the foods that contain flavonoids

Decreases production of the COX-1 and COX-2 enzymes that cause systemic inflammation
Anti-histamine component in Cysta-Q (Farr Laboratories) and CystoProtek (Algonot), both studied for IC/BPS with successful results
Vegan, gluten-free, IC/BPS friendly, Kosher certified and contain no fillers or artificial ingredients

Belong to a class of antioxidants called flavonoids, which support capillary wall stability and healthy collagen development, balance immune response and provide cardiovascular protection by reducing the oxidation of LDL cholesterol.
