A pilot study exploring the effects of olfactory stimulation using white musk aromatic oil has shown promise in enhancing psychophysiological activities among participants.
Conducted by researchers at Kyushu University and The Next Day Inc., this investigation is among the first to merge chemical profiling with psychophysiological evaluations of aromatic oils.
Published on August 24, 2023, the study involved ten healthy volunteers subjected to both white musk aromatic oil and unscented conditions. Participants underwent rigorous assessments, including EEG (electroencephalogram), ECG (electrocardiogram), and saliva tests to measure amylase levels before and after exposure to scents.
The study registered under UMIN Clinical Trials Registry ID: UMIN000051972, sought to address the fragmented nature of previous research, which often examined aromatic oils and their physical and psychological impacts separately.
Notably, the results indicated significant mood improvements, with participants reporting feelings of 'gorgeous', 'sweet', and 'like' following exposure to white musk oil. Mood evaluations showed marked reductions in fatigue and anxiety levels, with the POMS2 (Profile of Mood States 2nd Edition) scale reflecting decreased disturbance among participants inhaling the aroma.
"This pilot study could be the first step toward the larger sample size experiment on olfactory stimulation," the researchers stated, highlighting the necessity for more comprehensive studies.
The methodology employed advanced techniques like thermal desorption gas chromatography/mass spectrometry (TDU-GC-MS) to proficiently profile the aromatic oils' compounds. Two significant components were identified: galaxolide, which formed the bulk of the oil, and tonalide, often utilized for enhancing scent profiles.
Further, physiological responses indicated notable changes, particularly among those exposed to aromatic stimulation. ECG results revealed shifts suggestive of relaxation and reduced tension, as represented through lower LF/HF (Low Frequency/High Frequency) ratios, indicating balance within the autonomic nervous system.
Dr. Zennifa, part of the research team, expressed optimism about the results, mentioning, "Mood evaluation under POMS 2 variables such as Fatigue-Inertia (FI), Tension-anxiety (TA) and TMD (total mood disturbance) were significantly decreased under white musk aromatic oil inhalation." This suggests potential therapeutic applications for managing stress and enhancing well-being through scent.
The interest behind white musk primarily stems from its prevalence as an appealing fragrance choice within both consumer and therapeutic contexts. Acknowledging this, the study sought to validate the aroma's psychological and physiological efficacy.
Recent findings from various disciplines have underscored the importance of sensory experiences, particularly olfactory stimuli, indicating they could significantly influence emotional well-being. While much remains to be understood about the nuances of fragrance impacts, the researchers aim to inspire broader investigations.
Overall, this pilot study lays foundational insights on the exciting intersection of aromatic stimuli and human neurophysiological responses, paving the way for future research endeavors. Further exploration could shed light on the potential benefits of specific scents, not only for personal enjoyment but as part of holistic therapeutic practices.
