NCT ID NCT07513831
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether smelling lavender essential oil for 20 minutes before orthopedic surgery could lower anxiety, stress, and depression. 128 adults in Jordan took part, with half inhaling lavender oil and the other half receiving usual care. Results showed that the lavender group felt calmer and less stressed before their operation, suggesting a simple, drug-free way to improve emotional well-being before surgery.
