Anti-inflammatory activity of betalain-rich dye of Beta vulgaris: effect on edema, leukocyte recruitment, superoxide anion and cytokine production

We have recently developed betalain-rich beetroot (Beta vulgaris) dye (betalain) to be used in food products. Betalain (30-300 mg/kg) intraperitoneal (i.p.) treatment diminished carrageenan (100 µg/paw)-induced paw edema and neutrophil migration to the paw skin tissue. Betalain (100 mg/kg) treatment by subcutaneous or per oral routes also inhibited the carrageenan-induced paw edema. Importantly, the post-treatment with betalain (100 mg/kg, i.p.)...
