Analgesic and Anti-inflammatory Effects of the Aqueous Leaf Extract of Dichrostachys cinerea
OKHUAROBO, AGBONLAHOR; GODSWILL, NWAMAIFE & OZOLUA, RAYMOND
Abstract
In this present study, the analgesic activity of the aqueous extract of the leaves of Dichrostachy
cinerea was investigated in mice using acetic acid-induced writhing and hot plate test, while the anti-inflammatory
activity was investigated in rats using the carrageenan and dextran- induced paw edema. The extract (400, 800mg/kg)
exhibited a dose dependent inhibition of abdominal writhing in mice compared to control. The effects of the extract
were not significantly different from that of aspirin. The extract (800mg/kg) caused a significant (p<0.01) increase in
pain threshold, at 60th minute post treatment in the hot plate test and the effects of the extract were lower than that of
morphine (4mg/kg). The extract (800mg/kg) and indomethacin (10mg/kg) at 1st hour and 2nd - 4th hour produced
inhibitions of the carrageenan-induced paw oedema versus control. The results also showed that the extract (800mg/kg)
produced inhibition of dextran- induced paw edema between 2nd hour and 4th hour compared to control. Overall, our data
suggest that the extract possesses anti-inflammatory and analgesic effects, which may be mediated solely by peripheral
mechanisms.
