Sweetgrass Hydrosol is the closest way to get to the essential oil of this plant. There is no known pure essential oil distilled from the plant material known as hierochole odorata. There are fragrance oils manufactured to smell like sweetgrass but they never capture the grassy dry smell of this plant and usually are too sweet. Also, they have no medicinal value. This hydrosol has been distilled from the true plant material and can be used as a mist for smudging or a tea. It takes a lot of plant material to distill a liter of pure sweetgrass hydrosol.
