	Latency (minutes)
Treatment (mg/kg)	0	30	60	90	120	150
Control	8.4 ± 1.4	11.9 ± 2.3	12.8 ± 1.2	12.4 ± 0.8	13.1 ± 1.0	13.2 ± 1.4
Morphine (10)	8.8 ± 1.9	30.0 ± 0.0*	29.4 ± 0.6*	28.1 ± 1.4*	24.5 ± 2.7*	26.2 ± 2.6*

Data are mean ± SEM values for 10 animals per group. Student-Newman-Keuls analysis shows that the morphine, extract (3.2 mg/kg), and extract (6.4 mg/kg) groups at 30, 60, 90, 120, and 150 minutes after administration are significantly different from the control group (*P < .05).
