Abstract

In the literature, inhalation of cosmetic fragrances, including natural extracts or natural essential oils, has been reported to induce brainwave changes. Angelica gigas (AG) and Cnidium officinale (CO) are widely used in East Asian countries as traditional medicines to improve health, but there have been no previous reports of inhaling their aromas and assessing changes in brain activity through electroencephalogram (EEG) recordings. In this study, the scent of natural herbal extracts such as Artemisia princeps var. orientalis (Compositae), AG, and CO was inhaled and evaluated whether emotional state changes were caused by olfactory stimuli, and brain activity was confirmed through EEG records before and after inhaling the scent of natural herbal extracts in subjects aged 20 to 30. We also used an electrocardiogram (ECG) to record the electrical activity of the heart during fragrance administration. The test results indicated that inhaling the scents of Compositae, AG, and CO extracts, as well as the positive control lavender, significantly increased the relative alpha power and the alpha/beta ratio of brain waves across the brain regions. The ECG recordings indicated that the inhalation of Compositae fragrance significantly decreased the low-frequency/high-frequency ratio, and that the inhalation of traditional herbal extract fragrances resulted in comfort and relaxation.

문헌에 따르면, 천연 추출물 또는 천연 에센셜 오일을 포함한 화장품 향의 흡입으로 뇌파 변화가 유도된다는 사례가 보고되어 있다. Angelica gigas (AG)와 Cnidium officinale (CO)는 건강을 개선하는 전통 약재로 동아시아 국가에서 널리 사용되고 있으나, 이들의 향을 흡입하여 뇌파(EEG)기록을 통해 뇌 활동 변화를 평가한 이전 보고는 없었다. 본 연구에서는, Artemisia princeps var. orientalis (Compositae), AG, and CO와 같은 천연 약초 추출물의 향을 흡입하고 후각 자극으로 감정적인 상태 변화가 야기되는지에 대한 평가를 하였으며, 20 ~ 30 세 시험대상자를 대상으로 천연 약초 추출물의 향을 흡입하기 전과 후에 뇌 활동을 EEG기록을 통해 확인하였다. 또한 향을 흡입하는 동안 자율신경계 변화는 심전도(ECG) 기록을 통해 심장의 전기적 활동을 관찰하였다. 시험 결과, 양성 대조군인 라벤더를 포함하여 Compositae, AG, CO 추출물의 향을 맡으면 뇌의 전반 영역에서 뇌파의 relative alpha power 와 alpha/beta ratio가 크게 증가하는 결과를 나타냈다. ECG 기록은 Compositae 향의 흡입이 low-frequency/high-frequency 비율을 유의미한 수준으로 감소시켰다. 결론적으로 전통 약초 추출물 향의 흡입은 뇌파와 자율신경계 변화가 유도하여 감성적 편안함과 심리적 안정감에 도움을 줄 수 있음을 확인하였다.
