A study was carried out to evaluate the anti-pyretic potential of the methanol extract of Mallotus peltatus (Geist) Muell. Arg. var acuminatus leaf, a folk medicine of Onge tribes of Bay Islands, on normal body temperature and yeast-induced pyrexia in Wister albino rats. The leaf extract at oral doses of 100, 200 and 300 mg kg(-1), p.o., showed significant reduction in normal body temperature and yeast-provoked elevated temperature in a dose-dependent manner and the anti-pyretic effect was comparable to that of standard anti-pyretic agent paracetamol (150 mg kg(-1), p.o.). The effect also extended up to 5 hours after the drug administration.
