Study to Investigate Effects of a Herbal Drug Compared to Placebo on Sleep (sleep-EEG)

Phase I, Placebo-controlled, Double-blind, Randomised, Single-centre Study of Single Cross-over Design to Investigate the Effects of the Herbal Preparation Neurapas® Balance Compared With Placebo on Sleep EEG, Mental Performance and Well-being

To demonstrate the influence of a herbal preparation containing hypericum, passionflower, and valerian on sleep structure, improvement of attention, and well-being in comparison to placebo.

Study Overview

Detailed Description

To demonstrate the influence of the herbal combination preparation Neurapas® balance on the objective sleep structure in comparison with placebo. A further aim was to investigate whether treatment with Neurapas® balance versus placebo brings about an improvement in attention and well-being and whether these changes are related to the improvement in the sleep structure.

  1. Does the administration of 3 x 2 Neurapas® balance tablets over a period of three days vs. placebo lead to an improvement in continuity of sleep?
  2. Does the administration of 3 x 2 Neurapas® balance tablets over a period of three days vs. placebo lead to an improvement in sleep architecture, especially an increase in deep sleep?
  3. Does the administration of 3 x 2 Neurapas® balance tablets over a period of three days vs. placebo lead to an improvement in morning attentional performance?
  4. Does the administration of 3 x 2 Neurapas® balance tablets over a period of three days vs. placebo lead to an improvement in morning well-being?
