Vital essential oil extracted from plants that grow in a harsh environment. For the “KOTOHA with yuica” series, we used our yuica essential oil extracted from forest trees in the natural environment. The energy of the intrinsic forest is stronger than that of organic plants. The spicy and sweet aroma of Nioikobushi (Anise-Magnolia) is derived mainly from 1-8 cineole, geranial, and neral. It has various efficacies, such as refreshing your mind and increasing concentration.
