Summary

This completed Phase 2 trial tested whether Neurexan, a homeopathic tablet, can improve sleep and reduce stress in 81 people with short-term insomnia. Participants took Neurexan or a placebo for 14 days. Sleep efficiency was measured using brain activity and other body signals, while stress was assessed through cold water hand immersion and hormone tests. The study aims to see if Neurexan offers real benefits over a dummy pill.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Neurexan (a homeopathic combination of passionflower, oat, coffee, and zinc valerianate)
What this could lead to: If it works, this could point toward a natural-like option for easing short-term insomnia and stress without strong side effects.
What could go wrong: This is a small Phase 2 trial with only 81 people, and homeopathic remedies often show no difference from placebo. Results may not be conclusive or generalizable.
