The methanolic extract of Lycopus europaeus was evaluated on central nervous system. The methanolic extract produced significant sedative effect at the doses of 200, 400 and 600 mg/kg (by oral route), compared to reference substance diazepam in hole board and thiopental -induced sleeping time methods. While the hypnotic effect was calculated at the doses of 800 and 1000 mg/kg via oral pathway significantly reduced in both the reestablishment time and number of head dips during the traction and hole-board tests. In conclusion, these results suggest that the methanolic extract of Lycopus europaeus possess potent sedative and hypnotic activities, which supported its therapeutic use for insomnia.
