Objective:
This study was designed to evaluate the anti-inflammatory activity of aqueous and 70% methanolic extracts of pollen grains of Typha angustifolia.
Materials And Methods:
Female Sprague Dawley rats were used for the study. The acute anti-inflammatory activity of pollen grains of T. angustifolia was studied using the carrageenan as phlogistic agent, whereas its chronic anti-inflammatory effect was investigated by the percentage inhibition of cotton pellet-induced granuloma.
Results:
Both aqueous and 70% methanolic extracts of pollen grains of T. angustifolia showed significant dose-dependent inhibition of carrageenan-induced paw edema as compared to the control (P<0.001). It was observed that both the extracts at dose of 125 mg/kg inhibited the granuloma formation by 44.30% which is higher than at dose of 500, 250 mg/kg, thus causing a significant (P<0.001) non-dose-related inhibition of granuloma formation.
Conclusion:
The results of this study indicate that extracts of pollen grains of T. angustifolia are effective in the treatment of both acute and chronic inflammatory conditions and thus support its traditional utilization.
