Objective:To scientifically verify the claims of our traditional healers on the anti-inflammatory activity ofCarica 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 of50-200 mg/kg doses of the extract to3groups of5 rats per group. The 4th group of5 rats was used as negative control and received2 mL/kg(IP) of physiological saline, while the 5th group of5rats 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 of30minutes post administration for further 2 hours. Percentage inhibition of oedema was calculated for each dose group and results were subjected to statistical analysis using studentt-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 ofC. papaya is perhaps proven.
