NCT ID NCT07192783
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is testing whether inhaling lavender oil three times a week for a month can reduce anxiety, improve sleep quality, and lower blood pressure in people with primary hypertension. Fifty participants will be randomly assigned to either receive lavender oil inhalation plus routine care, or routine care alone. Researchers will measure changes using standard questionnaires and blood pressure readings.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- lavender oil
- What this could lead to
- If it works, this could offer a simple, non-drug way to help people with high blood pressure feel less anxious and sleep better.
- What could go wrong
- This is a very small, early trial with only 50 people. The effects may be small or not last, and lavender oil is not a replacement for standard blood pressure medications.
