 "Traditionally, "sassafras tea" was prepared by steeping the bark of the roots (D. S. Correll and M. C. Johnston 1970). It was once considered a relatively pleasant drink. Several indigenous populations used sassafras twigs as chewing sticks, and sassafras root is used occasionally in commercial dental poultices.

-Safrole is found as a minor component in many Lauraceae and as the principal component (80%) of sassafras oil. It is suspected of causing contact dermatitis and of being hallucinogenic, especially in large doses; it is also considered to be both carcinogenic and hepatotoxic (W. H. Lewis and M. P. F. Elvin-Lewis 1977)." [[http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=233501217]]
