Background: Inflammatory diseases are a major cause of morbidity and disability of work force throughout the world. The treatment of inflammation with standard steroidal and non-steroidal anti-inflammatory drugs shares the risk of toxicity on various organ systems. Moringa oleifera, an herbal plant has been claimed to be effective in the treatment of various types of inflammatory conditions. However, there is lack of scientific studies to ratify these claims. Therefore, the present study was undertaken to explore the anti-inflammatory activity of aqueous extract of leaves of Moringa oleifera (AEMO) in experimentally induced inflammation in albino rats.

Methods: The study was commenced after obtaining approval from Institutional Animal Ethical Committee using AEMO leaves in Albino wistar rats (150-200 gm) of either sex. The anti-inflammatory activity was evaluated using carrageenan induced paw edema model, cotton pellet induced granuloma method and formaldehyde induced paw edema method. For each set of experiment, animals were divided in three groups of six animals each. In each experiment, 1st group was given normal saline (5 ml/kg/day), 2nd group was given standard anti-inflammatory drug dexamethasone (0.5 mg/kg/day) and 3rd group was given Moringa oleifera (200 mg/kg/day).

Results: Aqueous extract of Moringa oleifera leaves at dose of 200 mg/kg, p.o. exhibited the significant anti-inflammatory effect in all the models used in this study.

Conclusions: It can be concluded from our study that aqueous extracts of Moringa oleifera leaves possess anti-inflammatory activity.
