[What is Yakusugi essential oil?] "Yakusugi" is a general term for cedar that grows wild on Yakushima, the first World Natural Heritage Site in Japan. However, it is determined that only those that grow wild at an altitude of 500 m or more and have lived for more than 1,000 years can be called Yakusugi. Yakusugi essential oil is extracted from 100% natural resin components by steam distillation. The essential oil that can be extracted is very small, about 20 ml for about 5 kg of raw materials, and it is a highly rare essential oil. [Effects and efficacy of Yakusugi essential oil] Yakusugi essential oil is rich in biochemical components called "sesquiterpenes" that have plant-derived properties. In particular, most of the constituents of Yakusugi essential oil are based on terpenes, and effects such as high relaxing effects have been confirmed. 【High relaxing effect】 It is said that the reason why you feel refreshed when you smell the scent of Yakusugi essential oil is that the aroma components reach the brain through the nose and emit α waves that occur when you relax in the brain. [ Relaxation of tension (calming excitement)] It has been reported that the essential oil of Yakusugi contains a large amount of β-eudesmol among sesquiterpenes, and has the effect of suppressing the excitation of the sympathetic nervous system during mental stress loads. It also contains an ingredient called elemol, which is known to have a high healing effect and helps calm the excitation of the nervous system. [ Improvement of sleep quality ] The ingredients contained in the sesquiterpenes introduced earlier are also known to improve the parasympathetic nervous system and increase the stability of the autonomic nervous system. By increasing the parasympathetic nerves, the nerves calm down and lead to improved sleep quality. [Regulation of the autonomic nervous system] In addition, sesquiterpenes have been reported to regulate the autonomic nervous system, as an increase in brain α waves was observed by smelling the scent of this component. [Antibacterial action] The secret to the longevity of Yakusugi, which is said to be the longest-lived in Japan, is said to be the abundant amount of resin. This resin exerts antibacterial and insect repellent effects, and protects Yakusugi from foreign enemies for a long time, thousands of years. The resin is directly linked to essential oils and exerts antibacterial, disinfectant, antiseptic, and insect repellent effects. [How to use with an aroma diffuser] In the case of the ultrasonic type, which is diluted with water, 3~4 drops of essential oil per 100ml of water is a guideline, but if you want to try a strong scent, please feel free to adjust the amount of essential oil.
