POKEWEED.

Phytolacca Decandra L. a.

Synonym--Phytolacca Americana (L). a.

Pharmacopoeial Name--Phytolacca.

Other Common Names--Poke, pigeon-berry, garget, scoke, pocan, coakum,

Virginia poke, inkberry, red inkberry, American nightshade,

cancer-jalap, redweed.

Habitat and Range--Pokeweed, a common, familiar, native weed, is

found in rich, moist soil along fence rows, fields, and uncultivated

land from the New England States to Minnesota south to Florida and

Texas.

Description of Plant--In Europe, where pokeweed has become

naturalized from his country, it is regarded as an ornamental garden

plant, and, indeed, it is very showy and attractive with its reddish

purple stems, rich green foliage, and clusters of white flowers and

dark-purple berries.

The stout, smooth stems, arising from a very large perennial root,

attain a height of from 3 to 9 feet and are erect and branched, green

at first, then reddish. If a piece of the stem is examined, the pith

will be seen to be divided into disk-shaped parts with hollow spaces

between them. The smooth leaves are borne on short stems and are

about 5 inches long and 2 to 3 inches wide, ovate or ovate oblong,

acute at the apex, and the margins entire. The long-stalked clusters

of whitish flowers, which appear from July to September are from 3 to

4 inches in length, the flowers numerous and borne on reddish stems.

In about two months the berries will have matured and assumed a rich

dark-purple color. These smooth and shining purple berries are

globular, flattened at both ends, and contain black seeds embedded in

a rich crimson juice. This plant belongs to the pokeweed family

(Phytolaccaceae).

a. Phytolacca Americana L. by right of priority should be accepted

but P. Decandra L. is used in conformity with the Pharmacopoeia.

Description of Root--Pokeweed has a very thick, long, fleshy root,

conical in shape and branches very much resembling that of

horseradish and poisonous. In commerce it usually occurs in

transverse or lengthwise slices, the outside a yellowish brown and

finely wrinkled lengthwise and thickly encircled with lighter colored

ridges. It breaks with a fibrous fracture and is yellowish gray

within. The transverse slices show many concentric rings. There is a

slight odor and the taste is sweetish and acrid. The root when

powdered causes sneezing.

Collection, Prices and Uses--The root of the Pokeweed, which is

official in the United States Pharmacopoeia, is collected in the

latter part of autumn, thoroughly cleaned, cut into a transverse or

lengthwise slices, and carefully dried. It brings from 2 1/2 to 4

cents a pound.

The root is used for its alterative properties in treating various

diseases of the skin and blood, and in certain cases in relieving

pain and allaying inflammation. It also acts upon the bowels and

causes vomiting.

The berries when fully matured are also used in medicine.

The young and tender shoots of the pokeweed are eaten in spring, like

asparagus, but bad results may follow if they are not thoroughly

cooked or if they are cut too close to the root.
