Musk-root.

The Sumbul is supposed to be an aquatic plant. From the character of the root it is supposed to grow in low wet places. It has been used in the East as a perfume and incense in religious ceremonies, as well as medicinally. It is brought to St. Petersburg, and from thence to other parts of Europe.

Habitat. - Central Asia.

Part employed. - The root as imported.

Characters. - In the form of transverse sections from 2 to 4 or 5 inches in diameter, and from 1 to 1 1/2 inch in length, with a dusky light brown wrinkled epidermis and an interior porous structure, consisting of coarse, irregular, easily separable fibres. The fresh-cut surface of a transverse section presents, within the epidermis, an exterior white and spotted layer, and an inner yellow substance which forms the greater part of the root. The odour resembles musk; the taste, at first sweetish, becomes bitterish and balsamic; mastication produces an aroma and sensation of warmth; this effect is diminished by time. It is found to contain volatile oil and two balsamic resins and a crys-tallizable acid. Some brought from India is of a closer texture than that from Russia.
