Sassafras. - On account of its medicinal virtues, and the beauty of its foliage, it may be considered one of the most interesting of the American forest trees. The bark of the young stem and branches is smooth, and of a beautiful green color. When old, the bark becomes rough, and the tree is not so interesting as when in its younger state. The leaves vary in shape on the same tree, being sometimes oval, and without notches, and sometimes divided into lobes. The flowers are of a greenish-yellow hue, and appear in small clusters before the unfolding of the leaves, in May, and are slightly odoriferous. The leaves are four or five inches in length, and, upon their first appearance in the spring, they are downy, and of a slender texture. When placed in a cup of water, the leaves create a delicate transparent mucilage. The inner bark of the tree has a spicy flavor, which renders it a favorite substance for chewing, to such persons as must have something to stimulate the salival glands, and whose stomachs reject the nauseating poison of tobacco. The bark of the root is highly odoriferous, and was used sixty years ago, in some rural localities, as a substitute for more costly spices, in giving flavor to pies, puddings, cakes, etc.
