Studies on anti-inflammatory activity of spice principles and dietary n-3 polyunsaturated fatty acids on carrageenan-induced inflammation in rats.
The antioxidant spice principles curcumin and eugenol when given by gavage lowered the carrageenan-induced edema in the foot pads of rats. This lowering effect was dependent on the concentration, the time gap between the administration of spice principles and the induction of inflammation by carrageenan. Dietary lipids also influenced the extent of inflammation. Animals fed 10% cod liver oil [containing n-3 polyunsaturated fatty acids (PUFA)] for 10 weeks showed a significantly lower inflammation compared to that observed in animals fed diets supplemented with 10% groundnut oil (rich in n-6 PUFA) or 10% coconut oil (rich in medium-chain saturated fatty acids). Supplementation of diets with 1 weight% of curcumin did not affect the inflammatory responses of animals to carrageenan injection. However, supplementation of diets with 0.17 weight% eugenol further lowered inflammation by 16, 32 and 30% in animals fed coconut oil, groundnut oil and cod liver oil, respectively. Therefore, combinations of dietary lipids with spice principles like eugenol can help in lowering inflammation.
