Summary

This study tested whether a 5-minute session of smelling lavender essential oil can help reduce stress, anxiety, and improve satisfaction in emergency department patients. 60 adults admitted to the ER observation unit took part. Half received a lavender-scented tube to sniff, while the other half got an unscented tube. The main goal was to see if the approach was acceptable and easy to use, not yet to prove it works for everyone.

What this could mean

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

Active substance
lavender essential oil
What this could lead to
If it works, this could offer a simple, drug-free way to help patients feel calmer in the emergency department.
What could go wrong
This was a small, early feasibility study with only 60 participants. The results may not apply to all patients, and the effect may be due to the relaxing setting rather than the lavender itself.
