The essential oil of Nardostachys jatamansi (Valerianaceae), which has been used for a long time in aroma therapy, was investigated after inhalation or oral administration for its analgesic effect, anticonvulsant action, hypnotic effect and in vitro inhibitory activity on monoamine oxidase. This fragrance oil showed a significant analgesic effect in the phenylquinone-induced .writhing test, suppressed the convulsion induced by pentylenetetrazole and lengthened the pentobarbital-induced sleeping time in a time-dependent manner after fragrance inhalation or dose-independently by oral administration. Its inhibitory activity on monoamine oxidase was remarkable, showing $49.4\%$ inhibition at a concentration of 5.0 mg/ml. Six new terpenes with seven known compounds were detected by our GC-MS analytical conditions used. As a result, the essential oil fragrance of Nardostachys jatamansi would be clinically useful for a sedative by either inhalation or oral administration.

The fragrance has a great influence on consumers' cognition, emotional response, attitude, memory, and behavior since the human sense of fragrance is physically and neurologically closer to the hippocampus of the brain. The fragrance materials are exposed to humans ranging from skin interaction to inhalation. We have lots of stories and literature on the usage of fragrance in everyday life in Korea from the Dangun myth to present K-beauty cosmetics. In Korean history, such archives as Dong-Eui-Bo-Gam and Gyu-Gak-Chong-Seo at Joseon Dynasty clearly recorded the application of many weeds for the manufacture of various fragrance products. In recent times, fragrances in weeds have been being applied to touch the consumer's feelings. The present mini-review is an attempt to introduce and discuss fragrant weeds in the archives and in science journals, effects of fragrant weeds on the human electroencephalographic activity, and effects of fragrance on the behavior of consumers. This review could be useful for the development of natural cosmetic and perfumery products from fragrant weeds.

The present study was designed to evaluate central inhibitory effects of an essential oil from Acori graminei Rhizoma (AGR), the dry rhizomes of Acorus gramineus Solander (Araceae) upon fragrance inhalation (aroma therapy). Preinhalation of an essential oil of AGR markedly delayed the appearance of pentylenetetrazole-induced convulsion. Furthermore, the inhalation of an essential oil of AGR impressively inhibited the activity of ${\gamma}$-aminobutyric acid (GABA) transaminase, a degradating enzyme for GABA as inhalation period is lengthened.

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.

In this work, we evaluated the characteristics of flow field and uniformity of the nose-only exposure chambers for the inhalation toxicity test. Computational fluid dynamics (CFD) modeling was carried out to demonstrate uniformity of the nose-only exposure chambers. Because it is very important in the inhalation toxicity experiments that test materials are distributed uniformly to each holder of the chamber. The test was done with these 3 types of chamber with different form to develop inhalation toxicity evaluation system, easy-to-operate system among exposure chamber used for evaluating inhalation toxicity of environmental chemical mixtures. Through CFD interpretation, nose-only exposure chamber was made with the selection of the optimal conditions. For its evaluation, one type of fragrance was selected and measured particle size distribution of each port. The gene becoming luminous to green fluorescence was combined with GPT-SPE, a type of tGFP vector, to be inhaled to the mouse. Based on this, luminous intensity was checked. As a result, total particle number concentration of each port had average value of $3.17{\times}10^6{\sharp}/cm^3$ and range of the highest and lowest concentration value was approximately ${\pm}4.8%$. Autopsy of lung tissues of mouse showed that it had clearly better delivery of gene compared to the control group.
