Abstract

This study aimed to examine the effects of several essential oils on insomnia in dementia patients following transdermal treatment (aromatherapy). The mean change rates (%) of sleep biomarkers were compared between the single essential and jojoba (vehicle) oil massage groups in this study. The lavender (L) essential oil massage group demonstrated a significant decrease in the mean change rate (%) of 24-h urinary free cortisol, whereas the valerian (V) essential oil massage group demonstrated a significant increase in the mean change rate (%) of serum 5-hydroxytryptamine. In addition, a significant increase in the mean change rate (%) of 24-h urinary norepinephrine was observed in the chamomile (C) essential oil massage group only. Based on these results, valerian, lavender, and chamomile oils were mixed in different ratios to produce blending oils A (L:C:V=2:2:1), B (L:C:V=3:1:1) and C (L:C:V=1:3:1). The highest level of serum 5-hydroxytryptamine was observed after administering blending oil A. These results suggest that blending oil A might possess therapeutic effects against insomnia. Overall, it is hypothesized that the optimally blended essential oil will produce synergic effects when combined with hypnotic drugs.
