The best variety of cinnamon is obtained from Ceylon, and is the prepared bark of a tree of the natural order Lauraceae.

It is in the form of long, cylindrical pieces, thin, smooth, and of a yellow-brown color, with a fragrant odor, and a warm, sweetish, aromatic and slightly astringent taste. It contains a volatile oil, a slight amount of tannic acid, an acid peculiar to itself, cinnamic acid, mucilage, lignin, etc.

Medical Properties And Action

Cinnamon is an aromatic stimulant and astringent, being more powerful as a local than as a general stimulant. Its medicinal virtues principally reside in a volatile oil, oleum cinnamomi.

Therapeutic Uses

Cinnamon is chiefly used as an adjunct to other medicines, being seldom prescribed alone, though it is capable of allaying nausea and vomiting, and also relieving flatulence. Combined with chalk and with other astringents, it is well adapted for the treatment of diarrhoea. A strong decoction of cinnamon made by boiling one pound of the Ceylon sticks in a closed vessel for eight hours in three pints of water until the quantity is reduced to one pint, is recommepded by Dr. Carne Ross for the pain of cancer. Dose is one-half pint taken during the 24 hours soon after meals.
