# Does aromatherapy with orange blossom essential oil help PMS?

Yes, according to the study, but the result was borderline (p=0.05, which is at the threshold for significance). The orange blossom group improved more than the control group.

 Moderate study design

62 university students with PMS

## What they did

Double-blind trial with 62 university students. One group inhaled 0.5% citrus aurantium (orange blossom) essential oil during the luteal phase of their cycle, and the other group inhaled odorless almond oil. Symptoms were measured before and 1 to 2 months after.

## What they found

Mean scores of overall PMS symptoms decreased more in the orange blossom group than in the control group (p=0.05).

## What it means for you

Orange blossom aromatherapy may help PMS, but the statistical evidence is weak and borderline. The study was small and included only university students, so results may not apply to all women.
