The effects of inhaling three essential oils (lavender [Lavendular angustifolia], silver fir [Abies alba], and grapefruit [Citrus paradise]) against restraint stress were investigated in mice. Serum cortisol levels were significantly increased in the 1h-restraint group. Also, silver fir and grapefruit oils prevented the elevation of cortisol levels under experimental conditions. Inhalation of 10% lavender oil for 30 min before inducing stress significantly inhibited restraint-induced hypothermia. We also investigated the effects of restraint stress on triglycerides, total cholesterol, and high-density lipoprotein cholesterol. It was found that the concentration of triglycerides in the serum samples increased after restraint stress. Silver fir essential oil inhibited elevation of triglyceride levels. Taken all together, the correlation of herb essential oil inhalation against restraint stress in animals can partly be explained.

The effects of aroma mixed oil with Chamomile, Lavender and Sandalwood on atopic dermatitis in NC/Nga mice were examined. The NC/Nga mice were divided into BMAC group, FK 506 Oinment (Tacrolimus Hydrate) group, and CLS group to get curative power of CLS. The amount of total IgE and IgG1 was measured and the severity of atopic dermatitis was assessed by the scoring procedure in NC/Nga mice. Topically applied CLS significantly suppressed the level of serum IgE and IgG1 in NC/Nga mice and FK506, used as reference drugs for atopic dermatitis, also exhibited suppressive effects against level of IgE and IgG1. The level of IgE was lower in the CLS group than in the FK506 group while the serum IgG1 level in the FK506 group was lower than in the CLS group. The treatment with FK506 and CLS reduced the skin inflammation index, especially the severity degree of atopic dermatitis in the skin lesioned NC/Nga mice by naked eyes was improved by treatment of FK506 and CLS. The results suggest that treatment of CLS in NC/Nga mice with atopic dermatitis have an beneficial therapeutic effects on reducing the level of IgE and IgG1 and accelerating repair of skin lesion.

We studied the physical, chemical, biological, and antimicrobial effects of eight types of essential oils used in the cosmetics industry: lavender, tea tree, rosemary, juniper berry, Chamaecyparis obtusa, cypress, cedar wood, and pine. Lavender oil had a linalyl acetate (an ester chemical compound) content of 48% and radical scavenging activity of 22.36% at 5,000 ppm. Tea tree oil had radical scavenging activity of 43.94% at 5,000 ppm and antimicrobial activity against S. aureus, S. epidermidis, S. mutans, and C. albicans in each 6, 3.5, 6.5, and 5 mm, respectively. Chamaecyparis obtusa oil had the highest acidity (pH 2.64) compared with the other oils, and sesquiterpene compounds were found to have 19.20%. Cedar wood oil had the highest specific gravity and refractive index compared to the other oils and had a sesquiterpene content of 99.73%. The radical scavenging activity of cedar wood essential oil exceeded 39.68% at 5,000 ppm. The clear zone, indicating antimicrobial activity against P. acnes, P. ovale, and C. albicans, was 3.5, 6, and 6 mm, respectively, at a concentration of 1% cedar wood oil. Results showed that with a high sesquiterpene content, the antioxidant effect was generally, but not always, high, suggesting that this is determined according to composition of the compound rather than presence of each antioxidant. The results indicate that antimicrobial activity is determined by the existence of each antimicrobial ingredient rather than terpene composition.

Traditional Chinese medicine has treated diseases and improved health in nature-based experience. Advanced nations began to be interested in naturopathic therapy in the late 19th century and it led China to research aromatherapy. This study searched previous researches related with aromatherapy and generally analyzed aroma oil, applied body parts, methods of use, and period of use. For research contents, scientific and society journals from 2000 to 2019 related with aromatherapy were searched in CNKI(www.cnki.com) and WANFANG DATE(www.wanfang.com). Finally, 30 papers were selected through 5-step qualitative evaluation and expert review and analyzed. Frequency and percentage(%) were calculated by means of the Excel 2013 Program and represented by a chart. The results of analyzing aromatherapy trends are as follows. All 30 papers were researched in the medical society. The most common symptom was irritation and anxiety that appeared in 13 papers. Lavender oil and bergamot oil were commonly used aroma oil. Commonly applied part and method were nose and nasal inhalation. For aroma oil associated with symptoms, lavender oil was the best in irritative, anxious, and negative emotion, depression, labor pain, sleep disorder, migraine, tension, and vomiting, pain, and fatigue after operation. Lemon, ginger, and peppermint oil was good for nausea. Based on the findings, this study derived applied body parts, methods of use, and period of use in aromatherapy. However, most aromatherapy was used for patients in the nursing and medical fields in the simple form of inhalation and local massage. This study will suggest a standard ground that aromatherapy is good for pain, colic pain, and tension in a short period but needs a long period for the efficacy of psychological and neurological symptoms.

In the saponification to manufacture plant fatty acid hard soap, the drying process is required for its water evaporation and hardness. This study mixed it with essential oil(E.O) with high volatility instead of adding synthetic flavor. And it comparatively observed the duration of flavor changing to the additive ($TiO_2$) and the drying period of the major flavor component (Linalool, Linalyl acetate) in the essential oil (Lavender E.O) contained in the soap during the soap manufacture by using GC-MS. Advanced researches have mostly dealt with the utility of plant hard soap, and those related with the volatility of flavor have been hardly conducted. Regarding the volatility of linalool contained in the soap, the soap mixed with $TiO_2$ showed a higher reduction ratio up to the 12th week; however, at the point of the 20th week, it reduced to a similar level. Although Linalyl acetate did indicate a slight difference according to the mixture of $TiO_2$, the volatility was shown similar up to the point of the 20th week. During the 20 weeks of drying, the residual rate of linalool was found to be higher than that of Linalyl acetate regardless of the mixture of $TiO_2$. It has been found that the flavor component of lavender essential oil with the duration of two or so days at the room temperature remains for 20 weeks (or 5 months) when it is manufactured through the mixture of plant fatty acid hard soap.

This study was conducted to look at the antimicrobial synergistic effect of blended oil into the target skin flora. The essential oils used in antimicrobial test were 100% eucalyptus (EU), lemon (LE), lavender (LA) and four blended oils, EU+LE, LE+LA, EU+LA, and, EU+LE+LA in ratio of 1:1 and 1:1:1 respectively. As a result, LE showed the highest, LA showed the lowest antimicrobial activity among single oil group. In blended oil group, antimicrobial activity of the EU + LA showed significantly increasing effect than the sum of the antimicrobial activity of the single oil. However, the antimicrobial effects of the blend of three oils did not show any synergistic effect. This result showed that the interaction between the chemical components constituting the oil than the number of blended oil seems more significant on the synergistic effect. Therefore, blending essential oil based on scientific evidence becomes more necessary in the future.

Purpose: This study was aimed to evaluate the effect of blending oils on atopic dermatitis (AD) model of NC/Nga mice. Methods: Adult NC/Nga mice were assigned to 1 of 3 groups: control group (C, n=8), experimental group [AD-induced group, blending oil-treated group (E=8, 8)]. Mice in the E group were given a treatment of blending oils such as Lavender, Rosemary and Lemon Balm (LRL) for 2 sessions (every day) for 6 days. Results: The AD-induced mice with LRL blending oils treatment showed a significant decrease in epidermal thickness, number of mast cells and degranulation, expression of TNF-${\alpha}$ and scoring of sensual assessment. Conclusion: LRL blending oils may be a putative resource for the cure of or treatment of AD by the diminution of AD-pathological factors such as the epidermal thickness, the number of mast cells and degranulation as well as the expression of TNF-${\alpha}$.
