Sassafras albidum — sassafras

Facts

Sassafras is a tall shrub or tree that produces three shapes of leaves: a mitten-shaped leaf with one large lobe and a small "thumb"; an oval leaf, and a three-lobed leaf. The waxy, glossy leaves produce an aromatic mucilage. Sassafras oil has been extracted from the bark to create an aromatic additive to soaps and perfumes and provide an antiseptic. Although it was once widely revered as a medicinal panacea for many ills, today its uses are more limited. The wood is soft but flexible, used for making barrels and some furniture. The leaves provide important forage for deer.
