Efficiency study of chamomile and Thyme essential oil about the basal layer & sebaceous gland in dry-skin induced by surfactant is as following : 1. Formal observation of outer skin layer and basal layer There was refreshing effects about Surfactant induction skin inflammation in Chamomile, Thyme essential oil processing group but effect in surface layer appeared by higher thing in Chamomile essential oil and it could know that thing which do not use Thyme essential oil in case Thyme essential oil is ultraviolet rays allergy at skin care because Melanocyte appear on the surface is bigger than Chamomile essential oil that it was usefully reaction in basal layer. 2. Formal observation result of sebaceous glands. There are few damages in all group but there is recuperative through excessive water damage by excessive a sebaceous gland made of mulberry bark secretion because Thyme essential oil application group cause chapped skin phenomenon after surface-active agent processing but is seen that difference does not exist greatly and Thyme essential oil that general skin is strong in permeation is effective, but Surfactant induction skin inflammation estimates that Chamomile essential oil is effective. Therefore, it was considered that use of Chamomile essential oil is effectiveness than Thyme essential oil by essential oil used for recovery after damage of inflammation etc..

Atopic dermatitis is one of the most common skin disease in children and a characteristic chronically recurrent form of dermatitis with a hereditary tendency, affecting infants and may extend to the childhood or th the adult age. Environmental factors, stress, and foodstuffs such as milk, egg may cause atopic dermatitis. Nc/Nga mice were used as an animal model for human atopic dermatitis. The divided by 4group such as normal group, BMAC group, FK506 group, MR group for this study raised in conventional conditions. To investigate effect of Chamomile German on atopic dermatitis in NC/Nga mice, the serum IgE and IgG1 level were measured while the severity degree of the skin lesion was examined by the naked eyes of two volunteers who were unaware of the treatment status. The results were the followings. 1. The score on the severity degree of skin dermatitis in FK 506 and MR group was lower than that in control group. 2. The serum IgE level in control group was higher 25% than that in normal group. 3. The serum level of IgE in FK506 and MR group compares to control group was decreased. 4. The serum IgG1 level was decreased more than 3.5 times in FK506 compared to control group while MR group had significantly less the serum IgG1 than control group. From the above results, treatment of Chamomile German oil had the effect on atopic dermatitis in NC/Nga mice. If scientific researches on aroma oil are performed in various way, aroma oil will be used to cure skin dermatitis as a alternative therapy in the future.

The essential oils from whole plant, flower, seed, stem and leaves of domestic chamomile were extracted by simultaneous distillation-extraction and analyzed by GC/ MSD/IRD and retention index matching. The experimental results revealed the presence of over 31 volatile components. Major components were chamazulene, bisabolol, bisabolol oxide A, B. The contents of these major components which possess the pharmacological effects were found to be flower(75.1%), seed(76.6%), stem and leaves(10.09%), whole plant (48.9%), respectively, in domestic chamoile oil, whereas found to be flower(49.2%) in foreign chamomile oil. These results suggest that the usefulness of domestic chamomile is promising because of high contents of these four major components which posses pharmacological effects.

Purpose: In this paper, we show our blending ratio of 10 types of Essential Oils that survives beneficial bacteria and kills harmful bacteria in the scalp, and we investigate the possibility of application of our blending ratio to the development of anti-dandruff products and the possibility of being used as a raw material for clinical beauty and customized cosmetics. Methods: The scalp microorganisms used in our study were M. furfur, S. epidermidis, E. coli, and P. nitroreducens. There are a total of 10 Essential Oils such as True Lavender, Lime, Roman chamomile, Rosemary camphor, Cedarwood, Geranium, Clove, Tea tree, Palmalosa, and Peppermint. The antibacterial test of the blended Essential Oil was carried out according to the test method of the standardized evaluation methodology of "Food and Food Additives Code". Since M. furfur is related to the growth of sebum in the scalp, in this study we used the fnLNB and the fnLNA with 20 ㎖ of whole fat cow milk added. Results: The blending ratio of EO, which inhibits dandruff-causing bacteria such as M. furfur, S. epidermidis, E. coli, and does not inhibit P. nitroreducens showing dominant growth in a healthy scalp, was B8(Clove 0.2%, Roman chamomile 0.5%, Tea tree 0.3%), B9(Geranium 0.1%, Palmarosa 0.1%, Roman chamomile 0.5%, Tea tree 0.3%), B10(Clove 0.1%, Geranium 0.1%, Palmarosa 0.1%, Roman chamomile 0.5%, Tea tree 0.2%). Conclusion: It is thought that the blending ratio of BEO obtained as a result of this study can provide a basis for use as an alternative to antibiotics in developing anti-dandruff drugs and emerge as a new alternative to solve scalp microbial imbalance. In order for EO to be used as a useful raw material for anti-dandruff preparation, researches on 1) Standardization (the effects of products differ according to the types, regions, climate, extraction methods, etc.), 2) Antimicrobial effects, 3) Safety, etc., must be established.

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.

Antibacterial activity of essential oils (Tea tree, Chamomile, Eucalyptus) on Staphylococcus aureus growth was evaluated as well as the essential oil-loaded alginate beads. The binding interactions between the cell and the essential oils were measured using an optical biosensor. The antibacterial activity of the essential oils to the cell was evaluated with their binding interaction and affinity. The antibacterial activity appeared in the order of Tea Tree>Chamomile>Eucalyptus, in comparison of the inhibition effects of the cell growth to the essential oils. The association rate constant and affinity of the cell binding on Tea Tree essential oil were $5.0{\times}10^{-13}\;ml/(CFU{\cdot}s)$ and $5.0{\times}10^5\;ml/CFU$, respectively. The affinity of the cell binding on Tea Tree was about twice higher than those on the other essential oils. It might be possible that an effective antibacterial activity of Tea Tree essential oil was derived from its strong adhesive ability to the cell, more so than those of the other essential oils.

This study examined the therapeutic effects of aromatherapy for the treatment of otitis externa in dogs. Eleven dogs with otitis externa were examined. The control group (5 dogs) was treated with susceptible antibiotics, and the experimental group (6 dogs) was treated with aroma-oil applied topically to the ear canal. The aroma-oil contained 10 ml sweet almond oil, 0.3 ml bergamot oil, 0.2 ml lavender oil, 0.1 ml tea tree oil and 0.1 ml roman chamomile oil. The blended aroma-oil (0.1 ml) was applied to the ear canal twice daily for 2 weeks. The authors examined the changes in the clinical signs, bacterial count in discharges, total WBC count and neutrophil/lymphocyte ratios in the two groups. The bacterial cell counts in the experimental group were significantly lower at one (p < 0.01) and two weeks (p < 0.05) after treatment than the control group. These results suggest that aromatherapy is an effective and practical treatment for otitis externa in dogs.

This study aimed to investigate whether inhaling the aroma of essential oils could alleviate physiological stress responses and mimic the effects of forest therapy in urban settings. Briefly, 31 participants underwent stress index assessments for two days and inhaled the selected plant essential oils. The effects of this treatment on physiological responses were determined through electroencephalogram (EEG) and heart rate variability (HRV) measurements taken before and after inhaling the aroma of essential oils, extracting results for low frequency (LF) and high frequency (HF) components of HRV, as well as 𝜃 and 𝛼 brainwave activities. The results indicated that lavender oil did not yield significant differences, whereas pine, chamomile, and cypress oils exhibited significant differences in effects. Overall, stress relief was associated with enhanced 𝜃 and 𝛼 brainwave activities, a decrease in the LF component and an increase in the HF component of HRV. Among the essential oils studied, pine oil was the most effective. These findings underscore the potential of plant essential oils in replicating the therapeutic benefits of forest therapy, even in urban environments. Further investigations into their utilization are warranted to better understand and harness their therapeutic potential.
