Commercially available Aztec marigold (Tagetes erecta) flower extract (Af.Cr) was evaluated for the in vitro antioxidant activity and in vivo analgesic effect on acetic-acid-induced abdominal writhing. The results revealed the presence of pronounced antioxidant potential in Aztec marigold flowers and a dose-dependent (100 and 300 mg/kg) analgesic effect. The antioxidant and analgesic activities...

The analgesic activity of the methanol extract of Phyllanthus lawii (MEPL) was investigated in Swiss albino mice with hot plate and acetic acid induced writhing models. The results suggested that MEPL possess potent analgesic activity. The MEPL produced a significant decrease in mice writhing induced by acetic acid suggesting peripheral analgesic activity and elevated mean basal reaction time i...
