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.
Native Range. Sassafras is native from southwestern Maine west to New York, extreme southern Ontario, and central Michigan; southwest in Illinois, extreme southeastern Iowa, Missouri, southeastern Kansas, eastern Oklahoma, and eastern Texas; and east to central Florida (8).verage annual rainfall varies from 760 to 1400 mm (30 to 55 in) within the humid range of sassafras. Of this, 640 to 760 mm (25 to 30 in) occur from April to August, the effective growing season.
