There was a significant difference in sympathetic nervous activity between the experimental, placebo, and control groups (F=3.78, p=.027), and the Stroop Color-Word interference test for concentration was significantly different between pre-test and at 30 minutes after treatment (F=7.40, p=.001).

Overview

May support sympathetic activation and concentration in healthy adults; hypothesis-generating, should not change practice.

Structured PICO

Does aroma essential oil inhalation improve autonomic nerve system response, electroencephalogram, and concentration in healthy adults?

P
Population
92 healthy adults
I
Intervention
Lemon and rosemary essential oil mixed in a ratio of 4:1, 0.1 ml dropped on gauze and naturally inhaled for a total of 30 minutes
C
Comparator
Placebo group (0.9% saline solution) and control group (no treatment)
O
Outcome
Autonomic nervous system response, electroencephalogram, and concentrationsurrogate

Inhalation of lemon and rosemary essential oil activated the sympathetic nervous system and partially increased concentration levels in healthy adults.
