The roots and bark of the sassafras plant contain a high level of safrole, which is known to cause cancer in rats. In 1960, sassafras was banned in the United States. in 1979, the Food and Drug Administration (FDA) banned the use of the plant and all products derived from it, including medicines and oils.
