Sassafras

Sassafras albidum

tree

Sassafras (Sassafras albidum) is an aromatic native tree, 30 to 60 ft tall, beloved for its mitten-shaped leaves (some with one "thumb," some with two, some plain), its brilliant orange-to-scarlet fall color, and the spicy root-beer scent of its crushed roots and bark. It famously flavored old-fashioned root beer and sassafras tea, and its dried young leaves are ground into file powder, the thickener for Creole gumbo. It suckers into aromatic thickets and is grown for its roots, bark, and leaves. An important caution: the root-bark oil contains safrole, which the FDA banned as a food additive, so modern use centers on the safrole-free leaf (file) and on enjoying the tree itself.

Good neighbors that attract beneficial insects or deter pests

• Spicebush: A fellow aromatic native understory shrub that shares the same woodland-edge conditions
• Wild Ginger: A shade groundcover for the dappled ground beneath the tree
• Fern: Thrives in the partly shaded, acidic soil under the canopy

• Laurel wilt →

  A serious fungal disease spread by an invasive beetle in parts of the South; remove and destroy affected wood and watch for sudden wilting

• Japanese beetles →

  Chew the soft leaves; hand-pick in the cool morning

• Sassafras weevil →

  Cause cosmetic leaf damage; healthy trees tolerate it

🌾 Harvest & storage

Pick young, tender leaves in late spring and summer to dry and grind into file powder - this is the safe, safrole-free harvest, stirred into gumbo at the end of cooking. The roots and root bark, source of the classic root-beer aroma, can be dug from suckers in fall or spring, but be aware their oil contains safrole; many people now grow sassafras chiefly for the leaves and the tree's beauty. Dry leaves quickly and store the green file powder airtight.

🥗 Nutrition & benefits

Sassafras is the source of file powder - dried, ground young leaves that thicken and flavor Creole gumbo, and which contain no safrole. The aromatic roots and bark gave old-time root beer and sassafras tea their flavor, but the root-bark oil contains safrole, banned by the FDA as a food additive, so harvest there is best avoided. The tree is also a superb ornamental for its fall color and a host for swallowtail butterflies.

⚠️ Toxicity & safety

The young leaves - and the file powder ground from them - are safrole-free and safe; this is the part used to thicken and flavor Creole gumbo. The roots and root bark are another matter: their oil is rich in safrole, which the FDA banned as a food and drink additive in 1960 because it is a liver carcinogen in animal studies. Do not brew tea or root beer from the raw roots or bark, and avoid sassafras essential oil. Grow the tree for its beauty and use only the leaves in the kitchen.
