This study was intended to evaluate the anti-inflammatory, antipyretic and analgesic activities of aqueous and ethanol extracts of Phrygilanthus acutifolius flowers in several experimental standard models in rats, following oral administration. The results showed that the aqueous extract significantly reduced the oedema induced by carrageenan within 1–5 h post-dosing at all dose levels used.On the analgesia property, acetic acid-induced writhing was significantly reduced. In the formalin test, the extract also significantly decreased the painful stimulus in both phases of the test. The tail immersion confirms central acting analgesic property of the extracts.Overall, the analgesic tests conducted revealed that the extract had central and peripheral properties. Its effects on pyresis were also appreciable. It significantly reduced fever at doses greater than 200 mg/kg within 2 h on yeast-induced hyperthermia in rats.
