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. Sassafras root was one of the ingredients of root beer; this use has now been banned.

Safrole ( p -allylyn ethylenediozybenzene) 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).
