Objective:To scientifically verify the claims of our traditional healers on the anti-inflammatory activity of Carica papaya(C.papaya) and possibly deduce its activities.Methods:0.1 mL of fresh egg albumin was injected into the right hind-paw of adult white Wistar rats to induce inflammation an hour post intraperitoneal(IP) administration of 50-200 mg/kg doses of the extract to 3 groups of 5 rats per group.The 4th group of 5 rats was used as negative control and received 2 mL/kg(IP) of physiological saline,while the 5th group of 5 rats was used as positive-comparative control and received(IP) 150 mg/kg of aspirin.Increases in diameter of the paw were measured with the aid of Veneer Calipers before extract administration and at interval of 30 minutes post administration for further 2 hours.Percentage inhibition of oedema was calculated for each dose group and results were subjected to statistical analysis using student /-test and analysis of variance(ANOVA).Results:All doses of extract showed a dose and time dependent inhibition effects of oedema(P【0.05).Conclusions:This work is at present though limited to animals,the anti-inflammatory activity of the seeds of C.papaya is perhaps proven.
