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.

Acinetobacter baumannii는 광범위한 항생제에 대한 저항성으로 인해 감염된 환자의 사망률이 높아지는 적색 경보 병원체로 분류됩니다. 이 연구에서 다제 내성 A. baumannii(MRAB)의 18가지 임상 분리 균주에 대해 일부 에센셜 오일(티트리, 로즈마리, 라벤더 오일)의 항균 활성을 평가하고자 하였다. Carbapenemase 선별을 위한 Hodge 시험법은 A. baumannii의 20 가지 균주가 모두 imipenem에 내성이 있음을 보여주었습니다. 다제 내성 미생물의 확인은 VITEK 시스템을 통해 수행하였다. 에센셜 오일의 항균 활성은 MRAB에 대한 디스크 확산 방법으로 평가하였다. 디스크 확산 방법에서 tee tree는 라벤더 오일에 비해 억제 크기가 가장 크게 증가했으며, 로즈마리는 항균 효과가 없었다. 티 트리 오일은 가장 일반적인 인간 병원균 및 MRAB 감염의 치료 및 예방을 위한 대체 천연 제품으로 유용할 것으로 보인다. 따라서 이 연구의 결과는 다제 내성 A. baumannii의 항균 효과를 입증했으며, 미래에 천연 에센셜 오일을 사용하는 손 소독제와 같은 항균제로 사용될 것으로 예상됩니다.

This study investigated the stimulative or sedative effects of inhaling fragrant essential oils (EOs) by using a forced swimming test (FST) with mice. This behavioral test is commonly used to measure the effects of antidepressant drugs. The inhalation by mice of EOs, such as ginger oil (p<0.05), thyme oil (p<0.05), peppermint oil (p<0.05), and cypress oil (p<0.01) resulted in 5% to 22% reduction of immobility. The same results were achieved when over-agitation was artificially induced in the mice by an intraperitoneal injection of caffeine (a psycho-stimulant). In contrast, inhalation of some EOs by the mice resulted in increased immobility. To evaluate more correctly the sedative effects of EOs, the immobility of over-agitated mice induced with caffeine was ascertained after the inhalation of various EOs. Inhalation of lavender oil (p<0.01) and hyssop oil (p<0.01) increased the immobile state in mice that were treated with caffeine. The results of this study indicate that the inhalation of essential oils may induce stimulative or sedative effects in mice.

본 연구에서는 화장품산업에 이용 중인 천연 에센셜 오일 8종(라벤더, 티트리, 로즈마리, 주니퍼베리, 편백, 싸이프러스, 시더우드, 파인)을 가지고 물리 화학적 분석과 생리활성 및 항균효과를 실험하였다. 라벤더오일의 경우 에스테르 성분인 linalyl acetate가 48% 함유되어 있었으며, 5,000 ppm의 농도에서 22.36%의 항산화능을 보였다. 티트리 오일의 경우 0.5% 농도에서 43.94% 항산화능을 보였으며 항균효과 또한 뛰어났다. S. aureus, S. epidermidis, S. mutans, C. albicans 균에 각각 6, 3.5, 6.5, 5 mm의 저해환이 측정되어 매우 우수한 품질의 에센셜 오일임이 확인되었다. 편백 오일의 경우 pH가 2.64로 가장 산성도가 높았으며, 세스퀴테르펜 성분이 19.20%로 확인되었다. 시더우드 오일의 경우 샘플 중 비중과 굴절률이 가장 높았으며 전체성분의 99.73%가 세스퀴테르펜으로 구성되어 있었다. 또한 5,000 ppm 농도에서 39.68% 항산화능을 보였다. 특히 1% 농도에서 P. acnes, P. ovale, C. albicans 균에 각각 3.5, 6, 6 mm의 저해환이 측정되어 매우 탁월한 항균효과를 보였다. 반면 세스퀴테르펜 함량이 증가할수록 비교적 항산화능도 높게 나오는 경우도 있지만 그렇지 않은 경우도 있어서 성분조성보다는 각각의 항산화 성분 유무에 따라 항산화능이 결정된다고 판단되며, 마찬가지로 항균력 또한 테르펜의 성분조성보다는 각각의 항균성분의 유무에 따라 항균력이 결정된다고 사료된다.

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.
