The present pharmacological investigation was undertaken to study the anti-pyretic activity of Guduchi ghrita formulations in albino rats against yeast induced pyrexia. Seven groups of six animals were used for the experiment. The yeast induced pyrexia method was standardized first by injecting 12.5% yeast suspension (s.c) followed by recording the rectal temperature at regular intervals. Then the evaluation of anti-pyretic activity of Guduchi ghrita formulations was carried out by using this standard procedure. Both the Guduchi ghrita samples including vehicle significantly attenuated the raise in temperature after three hours of yeast injection. After 6 and 9 hours of yeast injection also both the Guduchi ghrita samples attenuated the raise in temperature in a highly significant manner in comparison to both yeast control and vehicle control groups. The data generated during study shows that both the Guduchi ghrita formulations having significant anti-pyretic activity.
