CHAPTER XXXI.

FIELD PLANTS.

Dandelion.

Taraxacum Officinale Weber, (a).

Synonyms--Taraxacum taraxacum (L.) Karst: (a) Taraxacum densleonis

Desf.

Pharmacopoeial Names--Taraxacum.

Other Common Names--Blow-ball, cankerwort, doon-head, clock,

fortune-teller, horse gowan, Irish daisy, yellow gowan, one-o'clock.

Habitat and Range--With the exception, possibly, of a few localities

in the South, the dandelion is at home almost everywhere in the

United States, being a familiar weed in meadows and waste places, and

especially in lawns. It has been naturalized in this country from

Europe and is distributed as a weed in all civilized parts of the

world.

Description of Plant--It is hardly necessary to give a description of

the dandelion, as almost every one is familiar with the coarsely

toothed, smooth, shining green leaves, the golden-yellow flowers

which open in the morning and only in fair weather, and the round

fluffy seed heads of this only too plentiful weed of the lawns. In

spring the young, tender leaves are much sought after by the colored

market women about Washington, who collect them by the basketful and

sell them for greens and salad.

Dandelion is a perennial belonging to the chicory family

(Cichoriaceae) and is in flower practically throughout the year. The

entire plant contains a white milky juice.

Description of Root--The dandelion has a large, thick and fleshy

taproot, sometimes measuring 20 inches in length. In commerce,

dandelion root is usually found in pieces 3 to 6 inches long, dark

brown on the outside and strongly wrinkled lengthwise. It breaks with

a short fracture and shows the thick whitish bark marked with circles

of milk ducts and a thin woody center, which is yellow and porous. It

is practically without odor and has a bitter taste.

[Illustration: Dandelion (Taraxacum Officinale).]

Collections and Uses--Late in summer and in fall the milky juice

becomes thicker and the bitterness increases and this is the time to

collect dandelion root. It should be carefully washed and thoroughly

dried. Dandelion roots lose considerably in drying, weighing less

than half as much as the fresh roots. The dried root should not be

kept too long, as drying diminishes its medicinal activity. It is

official in the United States Pharmacopeia.

Dandelion is used as a tonic in diseases of the liver and in

dyspepsia.

Imports and Prices--Most of the dandelion root found on the market is

collected in central Europe. There has been an unusually large demand

for dandelion root during the season of 1907 and according to the

weekly records contained in "the Oil, Paint and Drug Reporter" the

imports entered at the port of New York from January 1, 1907, to the

end of May amounted to about 47,000 pounds. The price ranges from 4

to 10 cents a pound.

Soapwort.

Saponaria Officinalis L.

Other Common Names--Saponaria, saponary, common soapwort,

bouncing-bet, soaproot, bruisewort, Boston pink, chimney-pink,

crow-soap, hedge-pink, old maid's pink, fuller's-herb,

lady-by-the-gate, London-pride, latherwort, mock-gilliflower,

scourwort, sheepweed, sweet-betty, wild sweet-william, woods-phlox,

world's wonder.

Habitat and Range--By one or another of its many common names this

plant, naturalized from Europe, is known almost everywhere, occurring

along roadsides and in waste places.

Description of Plant--Soapwort is a rather pretty herbaceous

perennial, 1 to 2 feet high, and belonging to the pink family

(Silenaceae). Its smooth, stout and erect stem is leafy and sparingly

branched, the leaves ovate, 2 to 3 inches long, smooth, prominently

ribbed, and pointed at the apex. The bright looking, crowded clusters

of pink (or in shady localities whitish) flowers appear from about

June until far along in September. The five petals of the corolla are

furnished with long "claws" or, in other words, they are narrowly

lengthened toward the base and inserted within the tubular and pale

green calyx. The seed capsule is oblong and one-celled.

Description of Root--Soapwort spreads by means of its stolons, or

underground runners. But the roots, which are rather long are the

parts employed in medicine. These are cylindrical, tapering toward

the apex, more or less branched, and wrinkled lengthwise. The whitish

wood is covered with a brownish red, rather thick bark and the roots

break with a short, smooth fracture. It is at first sweetish, bitter,

and mucilaginous, followed by a persistently acrid taste, but it has

no odor.

[Illustration: Soapwort (Saponaria Officinalis).]

Collection, Prices and Uses--As already indicated, the roots without

the runners, should be collected either in spring or autumn. With

water they form a lather, like soap, whence the common names

soapwort, soaproot, latherwort, etc., are derived. The price ranges

from 5 to 10 cents a pound. The roots are employed in medicine for

their tonic, alterative and diaphoretic properties. The leaves are

also used.

Burdock.

Arctium Lappa L.

Synonym--Lappa major Gaertn.

Pharmacopoeial Name--Lappa.

Other Common Names--Cockle-button, cuckold-dock, beggar's-buttons,

hurrbur, stick-buttons, hardock, bardane.

Habitat and Range--Burdock, one of our most common weeds, was

introduced from the Old World. It grows along road sides, in fields,

pastures and waste places, being very abundant in the Eastern and

Central States and in some scattered localities in the West.

Description of Plant--Farmers are only too well acquainted with this

coarse, unsightly weed. During the first year of its growth this

plant, which is a biennial belonging to the aster family

(Asteraceae), produces only a rosette of large, thin leaves from a

long, tapering root. In the second year a round, fleshy, and branched

stem is produced, the plant when full grown measuring from 3 to 7

feet in height. This stem is branched, grooved, and hairy, bearing

very large leaves, the lower ones often measuring 18 inches in

length. The leaves are placed alternately on the stem, on long,

solid, deeply furrowed leafstalks; they are thin in texture, smooth

on the upper surface, pale and woolly underneath; usually heart

shaped, but sometimes roundish or oval, with even, wavy, or toothed

margins.

The flowers are not produced until the second year, appearing from

July until frost. Burdock flowers are purple, in small, clustered

heads armed with hooked tips, and the spiny burs thus formed are a

great pest, attaching themselves to clothing and to the wool and hair

of animals. Burdock is a prolific seed producer, one plant bearing as

many as 400,000 seeds.

[Illustration: Burdock (Arctium Lappa), Flowering Branch and Root.]

Description of Rootstock--Burdock has a large, fleshy taproot, which

when dry becomes scaly and wrinkled lengthwise and has a blackish

brown or grayish brown color on the outside, hard, breaking with a

short, somewhat fleshy fracture, and showing the yellowish wood with

a whitish spongy center. Sometimes there is a small, white, silky

tuft at the top of the root, which is formed by the remains of the

bases of the leafstalks. The odor of the root is weak and unpleasant,

the taste mucilaginous, sweetish and somewhat bitter. While the root

is met with in commerce in its entire state, it is more frequently in

broken pieces or in lengthwise slices, the edges of which are turned

inward. The roots of other species of Arctium are also employed.

Collection, Prices and Uses--Burdock root is official, and the United

States Pharmacopoeia directs that it be collected from plants of the

first year's growth, either of Arctium lappa or of other species of

Arctium. As Burdock has a rather large, fleshy root, it is difficult

to dry and is apt to become moldy, and for this reason it is better

to slice the root lengthwise, which will facilitate the drying

process. The price ranges from 5 to 10 cents a pound. The best root

is said to come from Belgium, where great care is exercised in its

collection and curing.

Burdock root is used as an alterative in blood and skin diseases. The

seeds and fresh leaves are also used medicinally to a limited extent.

Yellow Dock.

Rumex Crispus L.

Other Common Names--Rumex, curled dock, narrow dock, sour dock.

Habitat and Range--This troublesome weed, introduced from Europe, is

now found thruout the United States, occurring in cultivated as well

as in waste ground, among rubbish heaps and along the road side.

Description of Plant--Yellow Dock is a perennial plant belonging to

the buckwheat family (Polygonaceae), and has a deep, spindle shaped

root, from which arises an erect, angular and furrowed stem,

attaining a height of from 2 to 4 feet. The stem is branched near the

top and leafy, bearing numerous long dense clusters formed by

drooping groups of inconspicuous green flowers placed in circles

around the stem. The flowers are produced from June to August, and

the fruits which follow are in the form of small triangular nuts,

like the grain of buckwheat, to which family the dock belongs. So

long as the fruits are green and immature they can scarcely be

distinguished from the flowers, but as they ripen the clusters take

on a rusty brown color. The leaves of the yellow dock are lance

shaped, acute, with the margins strongly waved and crisped, the lower

long-stalked leaves being blunt or heart shaped at the base from 6 to

8 inches in length, while those nearer the top are narrower and

shorter, only 3 to 6 inches in length, short stemmed or stemless.

[Illustration: Yellow Dock (Rumex Crispus), First Year's Growth.]

The broad-leaved dock (Rumex obtusifolius L.), is known also as

bitter dock, common dock, blunt-leaved dock, and butter-dock, is a

very common weed found in waste places from the New England States to

Oregon and south to Florida and Texas. It grows to about the same

height as the yellow dock, to which it bears a close resemblance,

differing principally in its more robust habit of growth. The stem is

stouter than in yellow dock and the leaves, which likewise are wavy

along the margin, are much broader and longer. The green flowers

appear from June to August and are in rather long, open clusters, the

groups rather loose and far apart.

Fruiting Spike and Root.]

Description of Roots--Yellow Dock root is large and fleshy, usually

from 8 to 12 inches long, tapering or spindle shaped, with few or no

rootlets. When dry it is usually twisted and prominently wrinkled,

the rather thick, dark, reddish brown bark marked with small scars.

The inside of the root is whitish at first, becoming yellowish. The

fracture is short, but shows some splintery fibers. The root, as it

occurs in commerce, is either entire or occasionally split

lengthwise.

The darker colored root of the broad-leaved dock has a number of

smaller branches near the crown and more rootlets. Dock roots have

but a very faint odor and a bitter, astringent taste.

Collection, Prices and Uses--The roots should be collected in late

summer or autumn, after the fruiting tops have turned brown, then

washed, either left entire or split lengthwise into halves or

quarters and carefully dried. Yellow Dock root ranges from 4 to 6

cents a pound.

In the United States Pharmacopoeia of 1890 "the roots of Rumex

crispus and of some other species of Rumex" were official and both of

the above-named species are used, but the Yellow Dock (Rumex crispus)

is the species most commonly employed in medicine. The docks are

largely used for purifying the blood and in the treatment of skin

diseases.

The young root leaves of both of the species mentioned are sometimes

used in spring as pot herbs.
