Antipyretic activity
Ethanolic extract of bark of Geniosporum prostratum on yeast-induced pyrexia shown significant effect. Treatment with extracts at dose of 100 and 200 mg/kg body weight and paracetamol at dose of 25 mg/kg decreased the body temperature of yeast-induced rats. The results obtained from both standard- and extract-treated groups were compared with the control group. A significant reduction in the yeast-elevated rectal temperature was observed in the test drug. Percentage decrease in temperature by ethanolic extract of G. prostratum bark (100 and 200 mg/kg) and standard drug was found to be 1.40, 3.20, and 3.80 percentages, respectively.
