It's important to ensure that you use only cade oil that has been rectified to remove the carcinogenic constituents.
Rectified Cade Essential Oil is generally obtained by steam distillation of the crude extraction of cade oil through destructive distillation. According to Tisserand and Young, crude (unrectified) cade oil is potentially carcinogenic due to the presence of benzopyrene and should not be used internally or externally. The precaution is that only rectified cade oil should be used. [Robert Tisserand and Rodney Young, Essential Oil Safety (Second Edition. United Kingdom: Churchill Livingstone Elsevier, 2014), 222-223.]
