Evaluation of anti-pyretic potential of Jussiaea suffruticosa L. extract in rats.

A study was carried out to evaluate the anti-pyretic potential of the methanol extract of the aerial part of Jussiaea suffruticosa Linn. (MEJS) on normal body temperature and yeast-induced pyrexia in albino rats. Yeast suspension (10 ml/kg body wt.) increased rectal temperature after 19 hours of subcutaneous injection. The MEJS, at doses of 100, 200 and 300 mg/kg body wt. p.o., showed significant reduction in normal body temperature and yeast-provoked elevated temperature in a dose-dependent manner. The effect also extended up to 5 hours after the drug administration. The anti-pyretic effect of MEJS was comparable to that of paracetamol (150 mg/kg body wt, p.o.), a standard anti-pyretic agent.
