[Cor. from saxifrage, which now denotes a different kind of plants.] A kind of tree or plant, with aromatic properties, of the laurel kind, and allied to cinnamon, cassia, and camphor. Every part of the plant has a pleasant fragrance and a sweetish aromatic taste, which is strongest in the bark of the root. It occasionally grows to a height of 50 or 60 feet, and has a grayish and deeply-furrowed trunk. It is sometimes called the ague-tree. Its bark is used in dyeing, but also especially the bark of the root medicinally for rheumatism. The leaves are used in making root beer. The wood is tough, and does not decay.
