OBJECTIVE
Vanillosmopsis arborea Baker (Asteraceae) has high economic value from Chapada to Araripe and its bark essential oil is a potential source of alpha-bisabolol. The present study aimed to elucidate the antinociceptive and antipruritic properties of the essential oil of V. arborea Baker (EOVA) in mice.
METHODS
The antinociceptive activity was assessed using the capsaicin, glutamate, hot plate and cold allodynia tests. The antipuritic effects were also verified based on histamine-induced scratching behavior.
RESULTS
EOVA reduced the paw licking induced by capsaicin, but not that induced by glutamate. The essential oil increased the latency time in the hot plate, attenuated the cold allodynia induced by acetone and inhibited histamine-induced scratching behavior.
CONCLUSIONS
The experimental data demonstrated that EOVA showed central and peripheral antinociceptive activity and antipruritic effect.
