Quercetin
“Quercetin exerts its inflammatory activity by inhibiting inflammatory enzymes, including cyclooxygenase and lipoxygenase, and by decreasing prostaglandins and leukotrienes — well-known inflammatory mediators. In a mouse inflammation model, quercetin provided in the diet for 14 days decreased proinflammatory markers, including serum amyloid A, fibrinogen, and C-reactive protein (CRP).”
