Fig 3. Effect of khat extract and juice on swim speed during acquisition trials.

Each point across the line represents the mean ± SEM of swimming speed 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. Each group of rats was compared with rats that received T80W. KESC: khat extract subchronic, KESA: khat extract subacute, KHJ: khat juice.
