Summary

This study tested whether aromatherapy with lavender and peppermint essential oils can reduce nausea and anxiety in cancer patients during chemotherapy infusions. Forty adult outpatients who reported nausea or anxiety were given a gauze with one to two drops of oil to sniff as needed. After their infusion, they answered questions about how they felt.

What this could mean

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

Active substance
lavender and peppermint essential oils
What this could lead to
If it works, this could offer a simple, drug-free way to help cancer patients feel less nauseous and anxious during chemotherapy.
What could go wrong
This is a small, completed study with only 40 participants and no comparison group, so results may not be reliable or apply to everyone. Aromatherapy is not a substitute for standard medical care.
