Abstract:
Volatile oil of Psidium guajava leaves obtained by steam distillation was given orally to study its effects on the exudation and proliferative phases of the inflammatory reaction, using technique of carragenin induced paw edema and cotton pellets in male albino rats. The anti inflammatory activity as compared with ketorolac tromethamine. In carragenin induced edemas,. 0.8ml/kg of the volatile oil ad anti-inflammatory activity as that of ketorolac tromethamine. The oil was also found to be potent in cotton pellet granuom studies. Preliminary investigation revealed that the volatile oil fraction consist sesqueterpene which may be responsible for its anti inflammatory activity.
