CASSIA BUDS are the dried flower buds (perianth and ovary) of the cassia tree, and are mostly brought from China. They bear some resemblance to a clove, but are smaller, and when fresh have a rich cinnamon flavor. They should be chosen round, fresh, and free from stalk and dirt. They are used chiefly in confectionery, and have the flavor and pungency of cassia. The exports from Canton in 1844 were 21,500 lbs.; in 1850, 44,140 lbs., valued at 7,400 dollars. The average quantity of cassia buds imported into the United Kingdom, in each of the thirteen years ending with 1842, was 40,231 lbs.; the average quantity entered for home consumption in these years was 6,610 lbs., and the average annual amount of duty received was £312.

Cassia bark yields a yellow volatile oil, called oil of cassia, the finer kind of which differs but little in its properties from that of cinnamon, for which it is generally substituted; it has a specific gravity of 1071. The best is manufactured in China, where the wood, bark, leaves and oil are all in request. The cassia oil is rated at 150 dollars per picul, and the trade in this article reaches about 250,000 dollars.

CANELLA ALBA, or wild cinnamon, is a valuable and ornamental tree, growing about fifteen feet high, which is cultivated in South America and the West Indies for its pungent bark, which is shipped to this country in bales or cases, in long quills and flat pieces, something like cinnamon. Large old cuttings root readily in the sand. It is grown chiefly in the Bahama Islands, from whence we derive our supplies.

By the Caribs, the ancient natives of the West Indies, and the negroes, it was first employed as a condiment. In this country it is chiefly used as an aromatic stimulant and tonic, ranking between cinnamon and cloves. The bark possesses, however, no other quality than its hot spicy flavor and strong aromatic odor when exposed to the action of heat.

CASCARILLA BARK is obtained chiefly from the Croton cascarilla, a small shrub growing at St. Domingo, the Bahama Islands, and the Antilles. The chief portion comes from Eleuthera. In Hayti a pleasant kind of tea is made from the leaves. Other species of the family supply some of the bark of commerce.

From its strong and aromatic properties it has been found very efficacious in all febrile diseases, and vies with the Jesuits' bark; as a tonic it has very wholesome qualities, a pleasant and strong bitterness, and was for some time held in considerable repute among the faculty.

About twenty years ago, large shipments were made from the Bahamas. It was found, upon adulteration with hops, to reduce the cost of that article, and for the encouragement of the hop grower a prohibitory impost was laid upon it by the Home Government, consequently it became an unsaleable product.

The sea-side balsam, or sweet wood (Croton Eleuteria), from which some cascarilla bark is obtained, grows in the Bahama Islands and Jamaica, but almost all the bark imported comes from Nassau, New Providence. In 1840, 15,000 lbs. were imported for home consumption.

This bark produces the combined effect of an aromatic and of a moderately powerful tonic; but it does not possess any astringency. It has been employed as a substitute for cinchona. When burned it gives out a musky odor, and is often used in pastiles.

The value of this bark ranges, according to quality, from 17s. 6d. to 43 s. per cwt.
