S. albidum |
Sassafras is the common name and genus name for a group of deciduous trees in the flowering plant family Lauraceae, and in particular Sassafras albidum of the eastern United States. In general, three species are recognized, characterized by thick, deeply furrowed bark, tiny yellow five-petaled flowers, blue-black fruit, and three distinct leaf patterns on the same plant, with unlobed oval, bilobed mitten shaped, and trilobed leaves. There is an aromatic odor to the leaves, bark, and root.
Sassafras (S. albidum) is particular well-known for for an essential oil in the root bark (and other plant parts), which was once widely used to flavor root beer, as well as used medicinally and as a fragrance in perfumes and soaps. The plant also was used to brew a popular tea (sassafras tea). However, However, in the 1960s it was determined that the chief component of the essential oil, safrole, is a health hazard even when used in small amounts internally, and it has been banned as a food and flavoring additive in many countries, including the United States.
There are some other unrelated trees with the common name of sassafras outside of the Sassafras genus, including Oliveri cortex (black sassafras), Magnolia glauca (swamp sassafras), Umbellularia californica (California sassafras), and Antherosperma moschatus (Australian sassafras), among others.
Overview and description
In particular, the term is used for one of the three extant species in the order, Sassafras albidum', whose roots once were popularly harvested for their essential oil.
and in particular ****
a genus of three[1][2] species of deciduous trees in the family Lauraceae, native to eastern North America and eastern Asia.[2]
Sassafras trees grow from 15–35 m (50–120 feet) tall and 70–150 cm (2.5–6 feet) in diameter, with many slender branches, and smooth, orange-brown bark. The branching is sympodial. The bark of the mature trunk is thick, red-brown, and deeply furrowed. The wood is light, hard and sometimes brittle. It can be used to make a serviceable bow if properly worked.[citation needed] All parts of the plants are very fragrant. The species are unusual in having three distinct leaf patterns on the same plant, unlobed oval, bilobed (mitten-shaped), and trilobed (three pronged; rarely the leaves can be five-lobed).[3] They have smooth margins and grow 7–20 cm long by 5–10 cm broad. The young leaves and twigs are quite mucilaginous, and produce a citrus-like scent when crushed. The tiny, yellow flowers are five-petaled and bloom in the spring; they are dioecious, with male and female flowers on separate trees. The fruit are blue-black, egg-shaped, 1 cm long, produced on long, red-stalked cups, and mature in late summer.[1]
The name "Sassafras," applied by the botanist Nicolas Monardes in the sixteenth century, is said to be a corruption of the Spanish word for saxifrage.
Species
- Sassafras albidum (Nuttall) Nees - Sassafras, White Sassafras, Red Sassafras or Silky Sassafras. Eastern North America, from southernmost Ontario, Canada through the eastern United States south to central Florida, and west to southern Iowa and eastern Texas.
- Sassafras tzumu (Hemsl.) Hemsl. - Chinese Sassafras or Tzumu. Central and southwestern China. It differs from S. albidum in the leaves being more frequently three-lobed,[4] the lobes having a tapered acuminate apex (not rounded to weakly acute).
- Sassafras randaiense (Hayata) Rehd. - Taiwanese Sassafras. Taiwan. Treated by some botanists in a distinct genus as Yushunia randaiensis (Hayata) Kamikoti,[5] though this is not supported by recent genetic evidence which shows Sassafras to be monophyletic.[2]
Usage
Steam distillation of dried root bark produces an essential oil consisting mostly of safrole that once was extensively used as a fragrance in perfumes and soaps, food and for aromatherapy. The yield of this oil from American sassafras is quite low and great effort is needed to produce useful amounts of the root bark. Commercial "sassafras oil" generally is a by-product of camphor production in Asia or comes from related trees in Brazil. Safrole is a precursor for the clandestine manufacture of the drug MDMA (ecstasy), and as such, its transport is monitored internationally.
Importance to Livestock and Wildlife
Sassafras leaves and twigs are consumed by white-tailed deer in both summer and winter. In some areas it is an important deer food.[6] Sassafras leaf browsers include woodchucks, marsh rabbits, and black bears.[6] Rabbits eat sassafras bark in winter.[6] Beavers will cut sassafras stems.[6] Sassafras fruits are eaten by many species of birds including northern bobwhites,[6] eastern kingbirds, great crested flycatchers, phoebes, wild turkeys, catbirds, flickers, pileated woodpeckers, downy woodpeckers, thrushes, vireos, and mockingbirds. Some small mammals also consume sassafras fruits.[6]
For most of the above mentioned animals, sassafras is not consumed in large enough quantities to be important. Carey and Gill rate its value to wildlife as fair, their lowest rating.[6]
Culinary uses
The dried and ground leaves are used to make filé powder, a spice used in the making of some types of gumbo.
The roots of Sassafras can be steeped to make tea and were used in the flavoring of root beer until being banned by the U. S. Food and Drug Administration (FDA). Laboratory animals that were given oral doses of sassafras tea or sassafras oil that contained safrole developed permanent liver damage or various types of cancer. In humans, liver damage can take years to develop and it may not have obvious signs.
In 1960, the FDA banned the use of sassafras oil and safrole in foods and drugs based on the animal studies and human case reports. Several years later, the sale of sassafras oil, roots, or tea for human consumption was prohibited by law[citation needed]. Subsequently, both Canada and the United States have passed laws against the sale of any consumable products (beverages, foods, cosmetics, health products such as toothpaste, and others) that contain more than specific small amounts of safrole.[7]
Sassafras tea can also be used as blood thinner.
Sassafras was a commodity prized in Europe as a cure for Gonorrhea[8].
