This specimen isn’t your typical herbarium specimen of
Sassafras (Sassafras albidum). On
November 4, 1933, this piece of sassafras wood was collected by Otto Jennings
at Linn Run/Rock Run, about five miles south of Ligonier, Pennsylvania.
It is unclear what motivated this collection, since Jennings
did not normally collect wood like this. Given its bulky size, it is stored
separately with the fruit collection in the herbarium.
Sassafras is a medium-sized deciduous tree, native across eastern
North America. It is easily recognized by its uniquely mitten-shaped leaves.
The leaves are very aromatic when crushed in your hand, like many other species
in the Laurel family (Lauraceae). They also turn a beautiful red in fall.
Sassafras has long been used by humans for medicine and food, both by Native
Americans and later Europeans.
Ever wonder where the root in root beer comes from? Root beer was traditionally made from
sassafras roots or bark. But, since 1960, sassafras is no longer used in
commercially made root beers. The FDA has shown safrole (the aromatic oil in
sassafras roots and bark) to cause liver damage and/or cancer in high doses to
laboratory animals. Many commercial root beers nowadays use artificial flavors.

“What do you think?” “It’s vile.” “I know. It’s so bubbly and cloying and happy.” “Just like the Federation.” “But you know what’s really frightening? If you drink enough of it, you begin to like it.” “It’s insidious.” “Just like the Federation.” “Do you think they’ll be able to save us?” “I hope so.”
