This research quantitatively analyzes the relaxation effect towards psychological stress among many stresses. Subjects were 10 healthy male adults, and physiological parameters were Heart Rate (HR), Systolic Blood Pressure (SBP), and Secretory Immunoglobulin A (SIgA). The Profile of Mood States (POMS) test was conducted to analyze the psychological condition, and the Uchida-Kraepelin test was used to load stress for 25 minutes. Majoram essential oil was used for the experiment. HR and SBP significantly decreased after presenting the oil odor for stimulation. SIgA concentration increased from the control value on presenting the odor. After a 20 minute recovery, SIgA was still significantly high (p_0.05). This suggested that this odor has a relaxation effect towards stress.
