Antipyretic activity of 50%v/v poly herbal extract of Rubia cardifolia, Decalepis hamiltonii, Ficus racemosa was studied on normal body temperature and yeast induced pyrexia in rats. Yeast suspension (10 ml/kg, s.c.) increased rectal temperature after 19 hr of administration. The extract, in doses of 100, 200, 300 mg/kg (po) produced significant dose dependent lowering of normal body temperature and yeast provoked elevation of body temperature in rats. The effect produced was comparable with the standard antipyretic drug, paracetamol (150 mg/kg, i.p.).
