Brief summary
The purpose of this study is to examine and compare electroencephalography (EEG) changes in human subjects directly after inhalation of essential oils from five Thai aromatherapies. The investigators hypothesize that essential oils from Thai aromatherapies may influence the human EEG involving emotional relaxation particularly alpha wave EEG.
Detailed description
The subjects consisted of 22 male and 26 female subjects , ages between 20 to 30 years (mean age, 23.3 years). They were screened for excessive nasal congestion, drug and food taken, and neurological disorders prior to participation in the experiment. The experiments were approved by the Ethical Committee for Research Involving Human Research Subject, Naresuan University. All subjects read and signed an informed consent before participation.
