In the Present study, hydrodistillation of the fruits of C.cyminum Linn (Umbelliferae.) were investigated for antiinflammatory activity in carrageenan-induced rat paw oedema. The volatile oil showed dose–dependent inhibition of rat paw oedema, at dose of 0.1ml/kg, body wt i.p, when compared to control group. The activity was compared with that of the standard drug, diclofenac sodium.
