Effect of oral administration of the methanol extract of the stem bark of Boswellia dalzielii (BDME) on the mechanical hyperalgesia in PGE₂ (100 μl) inflamed rat paw. In panel (a), animals were treated 1 hour before PGE₂ injection and pain response was evaluated before treatment and after PGE₂ injection. In panel (b), treatments were given orally 1 hour after PGE₂ and response to pain was evaluated before PGE₂ injection and after treatment. N = 6; ^ap < 0.05; ^bp < 0.01; ^cp < 0.001 significantly different compared to vehicle.
