Rutin has dual activity: (1) Intact molecule (venous system): strengthens capillary walls by reducing endothelial permeability, inhibits MMP-2/MMP-9 (enzymes that degrade vascular basement membrane); reduces edema by sealing capillary leaks; inhibits PDI on platelets (novel anti-thrombotic without bleeding risk); (2) After gut bacterial hydrolysis → quercetin (systemic): NF-κB inhibition, COX/LOX inhibition, mast cell stabilization, antioxidant. The distinction is important: rutin's venous effects are separate from quercetin's anti-inflammatory effects.
