Rhopalocarpus similis is a plant endemic to Madagascar, traditionally to treat edema and joint pain. Inflammatory paw edema was caused by injection of carrageenan (2%). Pains manifested by abdominal contortions and licking of the sore paw were induced by injection of acetic acid (1.5%) and formalin (2%), respectively. The plant extract at doses of 150 mg/kg and 300 mg/kg, significantly inhibits (p<0.05) edema at 48.27 ± 8.27% and at 52.74 ± 7.90%), respectively. Indomethacin (10 mg/kg) used as a reference anti-inflammatory drug exerts an inhibition of 53.44 ± 7.10%. Untreated edemas of the paws of control mice were inhibited by 19.53 ± 2.79%. The plant extract also decreases the pain manifested by a significant inhibition (p<0.05) of abdominal contortions to 82.98 ± 1.74% with the two doses versus 81.91 ± 2.30% with the indometh..
