Summary

This study tests whether inhaling lavender essential oil can reduce nausea and vomiting after surgery under general anesthesia. About 128 patients will either receive lavender oil or standard care. The goal is to see if lavender can cut nausea by at least 10% without extra drugs.

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 (Lavandula angustifolia)
What this could lead to
If it works, this could offer a simple, drug-free way to ease post-surgery nausea.
What could go wrong
This is a small, single-center trial. The effect may be small or no better than standard care. Results may not apply to all surgeries.
