Editing Sassafras (section)

=== Oil and aroma ===
[[Steam distillation]] of dried root bark produces an [[essential oil]] which has a high safrole content, as well as significant amounts of varying other chemicals such as [[camphor]], [[eugenol]] (including 5-methoxyeugenol), [[asarone]], and various [[sesquiterpene]]s.  Many other trees contain similarly high percentages and their extracted oils are sometimes referred to as sassafras oil,<ref name="safroleContent">{{cite book |last=Abel |first=G. |author-link=<!--G.

Safrole is a precursor for the [[Clandestine chemistry|clandestine manufacture]] of the drugs [[3,4-Methylenedioxyamphetamine|MDA]] and [[MDMA]], and as such, sales and import of sassafras oil (as a safrole-containing mixture of above-threshold concentration) are heavily restricted in the US.<ref name="diversionDEA">{{cite act |title=Code of Federal Regulations |type=Title |number=21 |pages=a.h.1, f.1.i |quote=... the threshold is determined by the weight of the listed chemical in the chemical mixture |date=January 27, 2012 |article=§&thinsp;1310.04 |article-type=Article |url=http://www.deadiversion.usdoj.gov/21cfr/cfr/1310/1310_04.htm |access-date=2016-05-18 |archive-url=https://web.archive.org/web/20160417093716/http://www.deadiversion.usdoj.gov/21cfr/cfr/1310/1310_04.htm |archive-date=April 17, 2016 |url-status=live }}</ref>

Sassafras oil has also been used as a natural insect or pest deterrent, and in [[liqueur]]s (such as the opium-based [[Godfrey's Cordial]]), and in homemade liquor to mask strong or unpleasant smells.<ref name=Small2013 /><ref name = Duke2002 /> Sassafras oil has also been added to soap and other toiletries.<ref name="Barceloux" />  It is banned in the United States for use in commercially mass-produced foods and drugs by the [[U.S. Food and Drug Administration|FDA]] as a potential [[carcinogen]].<ref name=Dietz2007 />
