The name 'Sassafras,' applied by the Spanish botanist Monardes in the sixteenth century, is said to be a corruption of the Spanish word for saxifrage. The tree stands from 20 to 40 feet high, with many slender branches, and smooth, orangebrown bark. The leaves are broadly oval, alternate, and 3 to 7 inches long. The flowers are small, and of an inconspicuous, greenishyellow colour. The roots are large and woody, their bark being soft and spongy, rough, and reddish or greyish-brown in colour. The living bark is nearly white, but exposure causes its immediate discoloration. The roots are imported in large, branched pieces, which may or may not be covered with bark, and often have attached to them a portion of the lower part of the trunk. The central market for all parts is Baltimore. The entire root is official in the British Pharmacopoeia, but only the more active bark in the United States, where wood and bark form separate articles of commerce. The bark without its corky layer is brittle, and the presence of small crystals cause its inner surface to glisten. Both bark and wood have a fragrant odour, and an aromatic, somewhat astringent taste.
The tree, which has berries like those of cinnamon, appears to have been cultivated in England some centuries ago, for in 1633 Johnston wrote: 'I have given the figure of a branch taken from a little sassafras tree which grew in the garden of Mr. Wilmot at Bon.' Probably it was discovered by the Spaniards in Florida, for seventy years earlier there is mention of the reputation of its roots in Spain as a cure for syphilis, rheumatism, etc., though its efficacy has sincethen been much disputed.
The fragrant oil distilled from the rootbark is extensively used in the manufacture of the coarser kinds of perfume, and for scenting the cheapest grades of soap. The oil used in perfumes is also extracted from the fruits. The wood and bark of the tree furnish a yellow dye. In Louisiana, the leaves are used as a condiment in sauces, and also for thickening soups; while the young shoots are used in Virginia for making a kind of beer. Mixed with milk and sugar, Sassafras Tea, under the name of 'Saloop,' could, until a few years ago, be bought at London streetcorners in the early mornings.
