Steam distillation of dried root bark produces an essential oil consisting mostly of safrole that once was extensively used as a fragrance in perfumes and soaps, food and for aromatherapy. The yield of this oil from American sassafras is quite low and great effort is needed to produce useful amounts of the root bark.
The tender green leaves of the sassafras tree are gathered, dried, and ground to a powder. Only a few tablespoons of the powder will thicken a whole pot of Gumbo and give it a flavor thatâs spicy and pleasant. The fil&#233 must always be added after the pot is removed from the fire.
