Anti-pyretic and Analgesic Activity of Zingiber zerumbet

Abstract

The objective of the present study was to evaluate the anti-pyretic and analgesic activities of aqueous and ethanol extracts of Zingiber zerumbet rhizomes. The anti-pyretic activity of Zingiber zerumbet (25, 50 and 100 mg kg-1) was studied in Brewer's yeast-induced pyrexia in rats. The analgesic activity of Zingiber zerumbet (10, 25, 50 and 100 mg kg-1) was studied using acetic acid-induced writhing in mice. Both aqueous and ethanol extracts of Zingiber zerumbet showed significant anti-pyretic activities in Brewer's yeast-induced pyrexia in rats throughout the observation period of 8 h. The ethanol extract of the rhizomes of Zingiber zerumbet however significantly decreased the writhing movements in mice in acetic acid-induced writhing test. In conclusion, rhizomes Zingiber zerumbet have both analgesic and anti-pyretic activities.
