简要总结
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.
详细描述
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.

研究组 & 干预措施
Aromatherapy
Experimental procedures were conducted in the morning. Subjects individually entered the closed room where the temperature was kept at 25-26 oC and humidity 50-60%. The subjects were blinded using mask and were seated comfortably with eyes closed during experimental period. The EEG was recorded using silver electrodes. EEG activity was monitored 4 areas (F7, F8, T3 and T4) and ground electrodes. The experiments were divided into 3 parts. The first part, no-odor were recorded EEG activity for 10 minutes as a baseline. The second part, subject was exposure to the odor for 10 minutes as during inhalation. The last part, the odor was dispersed and assessed EEG activity for 10 minutes as after inhalation.
