This study addressed the influence of Aegopodium podagraria L. (goutweed) aerial part extract (100 mg/kg and 1 g/kg) and tincture (1 and 5 ml/kg) on the course of ethanol-induced as well as thiopental sodium induced narcosis. It has been shown that the extract at a dose of 1 g/kg, but not 100 mg/kg, significantly reduces the duration of ethanol-induced narcosis in male mice, the extract at a low dose decreases the onset of the loss of righting reflex. The tincture does not influence on the course of ethanol-induced narcosis, but significantly reduces the duration of sleep caused by thiopental sodium in male mice (at a dose of 1 ml/kg, but not 5 ml/kg), by this effect it is comparable with Hypericum perforatum L. extract at a dose of 100 mg/kg. Goutweed extract does not influence on the duration of thiopental-induced sleep.
