“…In this study, we could not find any effect on cognitive function, olfactory function or sleep quality by using aroma bath salt. A previous descriptive analysis of randomised clinical trials showed that results were different because of differences in the aroma therapeutic method used . Therefore, to obtain the effects of aromatherapy, we thought that it was necessary to consider the kinds of odour, the method of operation, the exposure time and selection of appropriate subjects.…”

“…A previous descriptive analysis of randomised clinical trials showed that results were different because of differences in the aroma therapeutic method used. 40 Therefore, to obtain the effects of aromatherapy, we thought that it was necessary to consider the kinds of odour, the method of operation, the exposure time and selection of appropriate subjects. However, despite our main negative finding, our results suggest that there is room for a further investigation to evaluate the relationship between improvement in sleep quality and improved cognitive function by using aroma bath salts.…”

Background Aromatherapy is a non‐pharmacological therapy for the improvement of dementia symptoms. This study aimed to assess the effects of aroma oil as a bath salt on cognitive function, olfactory function and sleep quality. Methods This was a randomised controlled trial. Overall, 49 patients were able to provide consent, and 35 were finally analysed (Alzheimer's disease: 10, mild cognitive impairment: 25). The patients were randomly assigned to use 0.1%, 0.5% or 1% aroma bath salt. During daily bathing, bath salt was added to the bath water, and the subjects remained in the bathroom for ≥10 min. The intervention period was 24 weeks, and the observation periods were 4 weeks before and after using the aroma bath salt. We performed the Touch Panel‐type Dementia Assessment Scale (TDAS), the Odour Stick Identification Test for Japanese (OSIT‐J) and the Japanese version of the Pittsburgh Sleep Quality Index (PSQI‐J) five times during the before and after observation periods and after the 12‐week intervention. Results There were no significant changes in the TDAS, OSIT‐J and PSQI‐J scores before and after the intervention in all groups. Moreover, there were no significant differences in the TDAS, OSIT‐J and PSQI‐J scores between the groups before and after the intervention. In the correlation analysis of changes in the TDAS and other tests during the intervention period, significant associations between TDAS and sleep latency and sleep disturbances, which are sub‐items of PSQI‐J, were observed in the use of 0.1% aroma bath salt group. Conclusions The use of aroma bath salt was not associated with improvement in cognitive function, olfactory function or sleep quality. However, sleep‐related aspects were associated with changes in cognitive function before and after use of aroma bath salt, which suggested that there is a link between improvements in sleep and that in cognitive function.

The diagnosis and treatment of Alzheimer's dementia (AD) has gained much attention due to the current and predicted prevalence of the disease. The biomarkers of neural inflammation, oxidative stress, genetics and the multiple medical etiologies of AD coupled with the poly-pharmacy of comorbid conditions and diseases associated with AD are complex. The medical diagnosis and treatments of AD need more reliability and integrative health regimens, such as supplementation with generally regarded as safe (GRAS) essential oils that could be implemented clinically to lessen the global economic impact to societies, and disruptions to families.

“…Essential oils, a part of the human diet, are obtained from aromatic and medicinal extracts from a wide variety of plants . They have raised scientific interest as potential natural agents because they can improve the quality of sleep, attenuate symptoms of dementia and Alzheimer's disease . And they also have positive effects on mood, stress, anxiety and depression .…”

This study was intended to examine the effects of navel orange (Citrus sinensis (L.) Osbeck) essential oil (OEO) on depression in the reserpine‐treated mice. And the chemical composition of OEO was analysed by gas chromatography (GC) analysis. The results indicated that the major compounds of OEO were terpenes. And OEO treatment produced an antidepressant‐like effect in mice, as indicated by the increased locomotor activity in the open field test (OFT) and attenuated dyslipidemia, but it had no effect on duration of immobility in the forced swim test (FST). Dietary OEO counteracted the reserpine‐induced hypothermia and palpebral ptosis. Moreover, OEO treatment increased the levels of serotonin (5‐HT) and dopamine (DA) in the mice brain. These antidepressant‐like effects of OEO are essentially similar to the effects of the antidepressant fluoxetine. And the action of OEO may be mediated by the central serotonergic and dopaminergic systems.
