Impact of Aloe vera (A. vera) extract administration on electroencephalographic architecture of sleep. Day-time EEG and EMG recordings were conducted in freely moving rats following 30 min post Aloe vera or diazepam administration for 4 hours. Accordingly, Aloe vera aqueous extract (200 mg/kg, i.p.) prolonged total sleeping time (A) as well as NREM sleep (B) while reduced sleeping time spent in REM (C). Data are represented as mean ± SD (n=6). * p < 0.05, ***p < 0.001 compared to control group
