Antinociceptive and antipyretic activities of amaranthus viridis linn in different experimental models.

Methanolic extract of whole plant of Amaranthus viridis L (MEAV), was screened for antinociceptive activity using acetic acid induced writhing test, hot plate test and tail immersion test in mice. In a similar way a screening exercise was carried out to determine the antipyretic potential of the extract using yeast induced pyrexia method in rats. Administration of the extracts was applied to both laboratory animals at the doses of 200 and 400 mg/kg body weight, respectively.
