Studies on the anti-inflammatory and analgesic activity of Cedrus deodara (Roxb.) Loud. wood oil.

The volatile oil extracted by steam distillation of the wood of Cedrus deodara was examined for its oral anti-inflammatory and analgesic activity at the doses of 50 and 100 mg/kg body weight. It produced significant inhibition of carrageenan-induced rat paw edema and of both exudative-proliferative and chronic phases of inflammation in adjuvant arthritic rats at doses of 50 and 100 mg/kg body weight. The oil at both tested doses was found to possess analgesic activity against acetic acid-induced writhing and hot plate reaction in mice.
