Effects of lozenge containing lavender oil, extracts from hops, lemon balm and oat on electrical brain activity of volunteers.

摘要: Within a randomized double blind, placebo controlled trial the electrical activity of human brain has been monitored using charge mode technology (Laplacian estimates) after exposure to lozenge containing 4 different herbal preparations (lavender oil, extracts from hops, lemon balm and oat) or matching without any active ingredients. Sixteen healthy volunteers (8 males 8 females) were tested within crossover design. After baseline recording each subject sucked 2 hours later second one. Recording was performed immediately finishing in hourly intervals thereafter. Comparison reference periods 10 min eyes open 5 closed, respectively, revealed increases alpha 1, beta 1 power at electrode positions Cz, P3, T3 T5 which even more pronounced application two later. Since changes repeatedly have attributed attentional states, this must be seen as indicator relaxational psychophysiological state. Changes alpha2 frequencies related working memory indicating that an increase can correlate for attenuating circuit. Increases beta1 presence anxiolytic drugs including major minor tranquilizers. The observed composition are therefore line with idea having induced state relaxation regeneration. This interpretation suggests one could expect ingestion better cope psychological emotional stress. data further proof computer aided quantitative EEG is very fruitful promising approach psychophysiology.
