Characterisation of the central nervous depressant activity of a commercially available valerian root extract.Arzneimittelforschung. 1993 Jun; 43(6):638-41.A
The evaluation of a commercially available valerian root extract (Valdispert) revealed pronounced sedative properties in the mouse with respect to a reduction in motility and an increase in the thiopental sleeping-time. A direct comparison with diazepam and chlorpromazine revealed a moderate sedative activity for the tested extract. The extract showed only weak anticonvulsive properties.
