Each point represents the mean ± SEM of escape latency, swim path-length, swim speed and thigmotaxis in rats (n = 6/ group) that received T80W, KESC (100 mg/kg, 200 mg/kg and 300 mg/kg), KESA (300 mg/kg) and KHJ 2.5 mL/kg.

***p < 0.001, **p < 0.01 and *p < 0.05 when each group of rats was compared with rats that received T80W.

KESC: khat extract subchronic, KESA: khat extract subacute, KHJ: khat juice.
