Used widely for purifying spaces thanks to its clean, crisp, and evergreen key notes, Japanese Cypress (Hinoki) has been used for centuries to build imperial palaces, temples and Shinto shrines and is considered sacred to the Japanese. The sweet evergreen note of Hinoki is an ideal natural air freshener, and the fragrance released is believed to both stimulate and relax the mind, calming and focusing the intellect while reducing stress and fatigue.
