Summary
"These data confirm that at recommended therapeutic doses, triazolam has detrimental effects on cognitive processes in healthy volunteers as found in previous studies. Valerian was without effect on either cognitive or psychomotor performance in healthy volunteers at the doses used in this study."
Study groups
Adults using 500 Milligram
Adults using 1000 Milligram
Summary
"Dependent measures included subjective and psychomotor variables. The valerian extract had no significant effects on any of the dependent measures. Diazepam, though, produced subjective effects as measured by four different rating scales, and impaired psychomotor/cognitive performance. The data suggest that acute administration of valerian does not have mood-altering or psychomotor/cognitive effects in young healthy volunteers."
