The healing effect of the aroma treated fabrics with lavender and lemon aromas was investigated by assessing the autonomic nervous responses of human body. For this cause Lemon and lavender microcapsules were coated on a cotton fabric using a water-based acrylic binder, respectively. And the study created a total of four aroma treated fabrics at a concentration of 2% and 5% respectively. Electrocardiogram(ECG), skin conductance, and Blood flow, of ten participants were measured for 30 sec at a stable condition, at a stress status (working memory task), and at a stimulation status (after rubbing aroma treated fabrics). Subjective sensibilities of the aromas were also evaluated. With regard to the responses of the autonomic nervous system, in order to understand how the values gained after the normalization process would cause different physiological signals between the stable state and the aroma-stimulated state as well as between the stress state and the aroma-stimulated state, the study conducted a non-parametric test, friedman test as well and analyzed tendencies. LF/HF turned out to be significantly different to the stress state, and according to the results of the post-hoc comparison, lemon 5% presented statistically significant differences among the lavender 2%, lavender5%, lemon2%. Lemon 5% stimuli increased stress but stimuli consisting of the lavender 2%, the lavender 5% and the lemon 2% decreased stress because of a psychological rest. And the stimuli of the lavender 2%, the lavender 5%, the lemon 2% presented a healing effect in this research.

This study aims to find a discriminatory way that can lower the dependence on imports of aroma essential oils and increase the value of herb plants that are growing in domestic demand and cultivation. To this end, through a study that analyzes and reproduces fragrance components without damaging the original material of domestically grown lavender flowers using the SPME method, we are trying to confirm the difference in fragrance composition from lavender essential oil and find the fragrance originality of domestically grown herb plants. A total of 38 kinds of lavender essential oils and 27 kinds of lavender flowers were analyzed as fragrance ingredients, Among them, the common ingredients were myrcene, d-limonene, 1,8-cineol, ocimene, p-cymene, α-terpinolene, camphor, linalool, linalyl acetate, bornyl acetate, 4-terpineol, and a-terpineol. In addition, among the fragrance components of the two samples, it was confirmed that the type and content of allergens of domestically cultivated lanvender flowers were low. As a result of the sensuality evaluation of 15 panels, domestic cultivated lavender flower reproduction scent was higher in favor of lavender essential oil, which has been used in the industry until now. It is also believed that lavender fragrance, which lowers the content of allergy-causing ingredients, can expand industrialization.

The objective of this study is to examine how different concentration of neurotransmitters in plasma between patients with dementia and normal people regarding the inhalation of lavender oil. This study subjects were 9 elderly patients with dementia who live in nursing home and 9 normal women. Before and after inhalation, they were collected blood sample. Norepinephrine (NE), serotonin (5-HT), dopamine (DA), and r-aminobutyric acid (GABA) concentration analysis were performed. Before inhalation, dementia patients were significantly different with the normal group in GABA and DA, NE. Following inhalation in experimental group, dementia patients and normal group were only significantly increased in 5-HT. But it did not significantly change in the other neurotransmitters. After inhalation, dementia patients were significantly different with the normal group in GABA and 5-HT. This result suggests that the increase of 5-HT release by the inhalation of lavender oil related to reduce the behavioral and psychological symptoms of dementia.

Purpose: The purpose of this study was to evaluate the effects of essential oil on oxidative stress, immunity, and skin condition in atopic dermatitis (AD) induced mice. Methods: This study was a $3{\times}3$ factorial design. Factors were oil type (Lavender, Thyme, and 2:1 mixture of lavender and thyme oil [blending oil]) and treatment period (0 day, 7 days, and 21 days). The samples were 45 mice with AD and randomly assigned to nine groups of five mice per group. The dependent variables such as superoxide radical, IgE, degranulated mast cells, and epidermal thickness were measured. Data were collected from February to April in 2014. Descriptive statistics, One-way ANOVA, Two-way ANOVA, and Tukey's HSD test were performed using the SPSS WIN 20.0 program. Results: Dependent variables were not statistically significantly different by the three oil types (p >.05). Essential oils such as lavender, thyme, and blending oil were all effective in reducing AD symptoms and especially 2:1 blending oil were most effective. There were statistically significant differences by the three treatment periods in all dependent variables (p <.001). There were statistically significant interactions between oil types and treatment periods in all dependent variables (p <.01). For decreasing superoxide radical, degranulated mast cells, and epidermal thickness, 2:1 mixed oil should be applied for at least 21 days. Otherwise to reduce IgE, 2:1 mixed oil should be used for at least 7 days. Conclusion: These findings provide bases for developing effective interventions for AD patients to manage their AD symptoms.
