is imported, about 125,000 pounds coming into this country annually.
Three to 8 cents is the price paid per pound.
BLESSED THISTLE.
_Cnicus benedictus_ L.
=Other common names.=—Holy thistle, bitter thistle, Our Lady’s thistle,
St. Benedict’s thistle, cursed thistle, spotted thistle. (Fig. 23.)
=Range and habitat.=—This weed has been introduced from Europe and
occurs in stony, uncultivated localities and waste places in the
Southern States and in California and Utah.
[Illustration: FIG. 23.—Blessed thistle (_Cnicus benedictus_ L.).]
=Description.=—Blessed thistle is an annual plant belonging to the
aster family (Asteraceæ). The round stems are erect, about 1 to 2 feet
high, branched, and rather woolly. The leaves are more or less hairy,
the lower ones borne on petioles (leaf stems), the upper ones sessile
(stemless) and clasping the stem. They are oblong-lanceolate and
wavy-lobed. The terminal yellow flower heads are surrounded by scales
of a leathery texture, which are prolonged into long, hard, branching
spines.
=Parts used.=—The leaves and tops should be collected when the plant
is in flower, about June, thoroughly and quickly dried, and kept in a
vessel from which moisture, light, and air should be excluded. They
have a somewhat disagreeable odor and the taste is very bitter.
Blessed thistle is employed in fevers, dyspepsia, and as a tonic to
restore the appetite.
=Imports and prices.=—This plant is cultivated in Germany, from which
country it is imported to a limited extent. The price per pound ranges
from 8 to 10 cents.
YARROW.
_Achillea millefolium_ L.
[Illustration: FIG. 24.—Yarrow (_Achillea millefolium_ L.).]
=Other common names.=—Milfoil, thousand leaf, thousand-leaved clover,
green arrow, gordoloba, nosebleed, bloodwort, carpenter’s grass,
sanguinary, soldiers’ woundwort, old man’s pepper. (Fig. 24.)
=Range and habitat.=—This herb is a common weed from the New England
States to Missouri and in scattered localities in other parts of the
country, occurring along roadsides, in old fields, pastures, and
meadows.
=Description.=—Yarrow is a perennial belonging to the aster family
(Asteraceæ). It is about 10 to 20 inches in height, its numerous
dark-green feathery leaves divided into very fine crowded parts.
The flowers are produced in abundance from June to September. These
are small, white (sometimes rose-colored), and are crowded in dense
flat-topped heads.
The odor of yarrow is strong and aromatic, very similar to that of
chamomile, and the taste is sharp and bitter. When this plant is eaten
by cows its bitter taste and strong odor are imparted to dairy products.
=Parts used.=—The entire plant is collected when in flower, and is
carefully dried. The coarser stems should be rejected. The plant loses
nearly four-fifths of its weight in drying.
Yarrow is a stimulant tonic, acts upon the bladder, and checks
excessive discharges.
=Imports and prices.=—This is an imported article, though not brought
into the United States in large quantities. The price of achillea or
yarrow ranges from 2 to 5 cents per pound.
CANADA FLEABANE.
_Leptilon canadense_ (L.) Britton. (_Erigeron canadensis_ L.)
=Other common names.=—Horseweed, colt’s tail, scabious, prideweed,
butter weed, fireweed, blood-stanch, cow’s tail, bitter weed. (Fig. 25.)
[Illustration: FIG. 25.—Canada fleabane (_Leptilon canadense_ (L.)
Britton).]
=Range and habitat.=—This weed is common in damp, sandy soils in fields
and waste places and along roadsides in many parts of the United
States, especially throughout the northern Mississippi Valley.
=Description.=—Canada fleabane is an annual weed belonging to the aster
family (Asteraceæ). The stem, which is bristly-hairy, or sometimes
smooth, varies greatly in height, according to the soil, being
sometimes only 3 inches high, and in favorable soil often reaching a
height of 10 feet. The larger plants are branched near the top. The
leaves are usually somewhat hairy, those scattered along the stem being
rather narrow, with unbroken margins, and the lower ones slightly
toothed. From June to November numerous heads of small inconspicuous
white flowers are produced, followed by an abundance of seed.
=Parts used.=—The entire herb is medicinal, and should be gathered
during the flowering period and carefully dried. It has a faint,
agreeable odor and a somewhat astringent and bitter taste. The fresh
herb on distillation yields a volatile oil which is sold as oil of
fleabane.
The common name “blood stanch” indicates the use of this plant for
arresting hemorrhages from various sources and the bleeding of wounds.
It is useful also in diarrhea and dropsy.
=Price.=—The price paid for erigeron or flea bane ranges from 6 to 8
cents per pound.
JIMSON WEED.
_Datura stramonium_ L.
=Other common names.=—Jamestown weed (from which “jimson” weed is
derived), thorn-apple, stinkweed, stinkwort, devil’s apple, mad-apple,
devil’s trumpet, fireweed, Jamestown lily, dewtry, apple of Peru. (Fig.
26).
[Illustration: FIG. 26.—Jimson weed (_Datura stramonium_ L.).]
=Range and habitat.=—Jimson weed is exceedingly common in fields and
waste places throughout the entire country with the exception of the
North and West. It is native in the Tropics and widely scattered in
nearly all warm countries.
=Description.=—This well-known rank and ill-scented poisonous weed
is an annual about 2 to 5 feet in height, and belongs to the potato
family (Solanaceæ). Its yellowish-green stems are stout, leafy, and
much forked. The leaves are large, 3 to 8 inches long, thin, smooth,
pointed at the apex and usually narrowed at the base, irregularly
waved and toothed, veiny, dark green on the upper surface and paler
green beneath. The rather large, showy flowers are produced from May
to September. They are white, funnel shaped, about 3 inches long, and
have a heavy odor. The seed pod is a dry, oval, prickly capsule, which,
when quite ripe, bursts open and discloses four valves, containing
numerous black, kidney-shaped seeds. (Fig. 27.) The seeds are
ill-smelling when fresh, as is the entire plant. They are dull black,
about one-sixth of an inch long, flattened, wrinkled, and marked with
small depressions.
=Parts used.=—Both the leaves and seeds are medicinal. The leaves
are collected at the time of flowering, the entire plant being cut
or pulled up and the leaves stripped and dried in the shade. The
unpleasant narcotic odor diminishes upon drying. The leaves are
poisonous, cause dilation of the pupil of the eye, and are used
principally in asthma.
For the collection of the seeds the capsules should be taken from
the plants when they are quite ripe, but still of a green color. The
capsules should then be dried for a few days, when they will burst open
and the seeds can be readily shaken out. These should now be carefully
dried. The seeds like the leaves are poisonous and possess the same
properties.
Occasional cases of poisoning of children occur from eating the seeds
of jimson weed and taking the flowers in their mouths.
=Imports and prices.=—From 100,000 to 150,000 pounds of stramonium
leaves (the name by which they are designated in the drug trade) are
imported into this country annually, and about 10,000 pounds of seeds
are imported.
The leaves will bring from 2½ to 8 cents per pound, and stramonium
seeds from 3 to 7 cents per pound.
[Illustration: FIG. 27.—Leaves, flower, and capsules of jimson weed.]
Purple thorn-apple.
The purple thorn-apple, technically known as _Datura tatula_, is very
similar to the jimson weed, possesses the same properties, and is
distinguished from it merely by its reddish stems and purplish flowers.
The leaves and seeds may be gathered with those of the jimson weed.
POISON HEMLOCK.
_Conium maculatum_ L.
=Other common names.=—Spotted parsley, St. Bennet’s herb, bad-man’s
oatmeal, heck-how, wode whistle, cashes, bunk, poison parsley, spotted
cowbane. (Fig. 28.)
=Range and habitat.=—Poison hemlock is rather common in waste places
and along roadsides, principally in the Eastern and Middle States. It
has been naturalized in this country from Europe.
=Description.=—From the close resemblance of the leaves of this plant
to parsley, it is sometimes mistaken for the latter and fatal cases
of poisoning have occurred. All parts of the plant are exceedingly
poisonous.
[Illustration: FIG. 28.—Poison hemlock (_Conium maculatum_ L.).]
Poison hemlock belongs to the same family as the parsley, namely, the
Apiaceæ. It is a biennial, about 2 to 6 feet in height, with a smooth,
hollow stem dotted with purple, and large leaves very much like those
of parsley. The numerous small white flowers are borne in rather showy
umbels (flat-topped clusters, with stems from one point) and appear
in June and July. The fruit ripens in August and September. The fruit
is grayish-green, ribbed, about one-eighth of an inch long, ovate,
laterally flattened, and smooth.
The entire plant possesses a disagreeable mousy odor, which is
especially noticeable when bruised.
=Parts used.=—The fruit and leaves are the parts used. The fruit should
be collected while still green but full grown, which in most localities
is some time in August. It should be dried in dark but well ventilated
places, and then stored in tight cans or boxes where it will not be
exposed to the action of light and air.
The poison hemlock leaves should be collected when the plant is in
flower, which will be in the second year of its growth. The stems
should be rejected. Contrary to the usual method of drying leaves and
herbs, the poison hemlock leaves may be quickly dried in the sun and
then kept in tightly closed vessels. The leaves will retain their green
color if properly cured. The odor is still very disagreeable, but not
so pronounced as in the fresh plant.
This very poisonous drug is used in rheumatism, neuralgia, asthma, and
in cases where the nervous system is in an excited condition.
=Imports and prices.=—The imports of conium or poison hemlock seed
amount to about 20,000 pounds annually, and from 10,000 to 20,000
pounds of the leaves are imported. The price paid for the seed is about
3 cents per pound, and for the leaves about 4 cents.
AMERICAN WORMSEED.
_Chenopodium ambrosioides_ L.
=Other common names.=—Mexican tea, Spanish tea, Jerusalem tea, Jesuit
tea, ambrosia. (Fig. 29.)
[Illustration: FIG. 29.—American wormseed (_Chenopodium ambrosioides_
L.).]
=Range and habitat.=—This strong-scented herb, naturalized in this
country from tropical America, frequents waste places around dwellings
and is found in streets, meadows, pastures, and grain fields from New
England to Florida, and westward to California.
=Description.=—American wormseed is an annual plant of the goosefoot
family (Chenopodiaceæ), attaining a height of from 2 to 3 feet. The
stem is grooved, usually much branched and leafy, the leaves oblong or
oblong lance-shaped, somewhat acute at the apex, the lower ones 1 to 3
inches long and wavy-toothed, the numerous upper leaves much smaller
and usually entire. From July to September the flowers are produced,
followed throughout the autumn by the fruits, both of which are green
and borne in crowded leafy spikes. The whole plant has a powerful,
disagreeable odor, due to the essential oil which it contains.
=Part used.=—The entire leafy part of the plant is sometimes employed
for the distillation of the oil, although the fruit alone is listed in
the Pharmacopœia of the United States. The fruit is distilled for the
oil, which it contains in large quantities.
The fruits are in the form of small grains, about the size of a pin
head, globular but slightly flattened, greenish, and inclosing the
small shining black seeds. They have the same powerful odor as the
plant, which does not diminish when the fruit is dried, and the taste
is bitter and pungent. American wormseed is an anthelmintic, that is,
it has the property of expelling worms.
The fruits of _Chenopodium anthelminticum_, another species of
wormseed, are collected with those of the species just described. This
plant is very similar to the American wormseed, the fruits being alike,
and the only differences being that in _Chenopodium anthelminticum_
the stem is slightly taller, from 2½ to 3½ feet high, the leaves are
more coarsely toothed, the flowers are borne in more elongated, usually
leafless spikes, the odor is more pronounced and disagreeable, and the
range and distribution of the plant are more limited.
Wormseed is cultivated to a considerable extent in parts of Maryland,
where the distillation of the plant for the oil is carried on.
=Price.=—In ordinary seasons the price paid for chenopodium or wormseed
ranges from 6 to 8 cents per pound. The oil distilled from wormseed is
at present selling at $1.50 per pound.
BLACK MUSTARD.
_Brassica nigra_ (L.) Koch. (_Sinapis nigra_ L.)
=Other common names.=—Brown mustard, red mustard. (Fig. 30.)
[Illustration: FIG. 30.—Black mustard (_Brassica nigra_ (L.) Koch).]
=Range and habitat.=—Black mustard, introduced from Europe, is a
troublesome weed in many parts of the United States. It is common in
almost every State in the Union along roadsides, in cultivated ground,
and in waste places, being especially troublesome in grain fields and
pastures. Both black and white mustards are cultivated in California.
This plant is a great pest in southern California, covering thousands
of acres and forming dense, impenetrable thickets over 6 feet in
height, in which birds have their nesting places, and, by eating and
excreting the seeds, help to spread this pernicious weed.
=Description.=—The rather stiff, dark-green, branching stem of black
mustard is from 4 to 6 feet in height. The lower part of the stems and
branches is more or less bristly hairy, but the upper part is usually
smooth.
The leaves are dark green, somewhat rough, with bristly hairs, and
are all borne on stalks. The lower leaves are lobed, the terminal
lobe being the largest and the two or more lateral ones smaller. The
leaves toward the top of the plant become lance shaped and are slightly
toothed.
The flowers of black mustard appear from June to September, and are
of a bright yellow color. They are rather small, scarcely a quarter
of an inch in diameter, the four petals spreading and each consisting
of a rounded blade with a narrow claw. The petals alternate with the
pale-green sepals or calyx lobes. The flowers appear in clusters at the
ends of the elongating stems, followed from July to November by the
numerous erect pods crowded against the stem in dense narrow clusters.
The pods are about 1 inch in length, quadrangular, smooth, and tipped
at the apex by the short, persistent style. The seeds contained in the
pods are very numerous, small, about one twenty-fifth of an inch in
diameter, globular, blackish brown, and finely pitted.
The plant is an annual, and if care is taken to prevent the
distribution of the seeds it is not difficult to exterminate. The seeds
possess great vitality, and may remain in the ground for years before
germinating.
=Collection of seeds.=—The tops may be pulled when most of the pods are
nearly mature, but before they are ready to spring open. They should
then be placed on a clean, dry floor or shelf, allowing the pods to
ripen and dry out, when they will burst open and the seeds can be
readily shaken out.
Mustard seed has no odor whatever when collected, not even when it is
powdered in its dry state, but as soon as water is added in grinding
it, the powerful, penetrating mustard odor is developed. The taste is
sharp and pungent.
WHITE MUSTARD.
_Sinapis alba_ L.
=Another common name.=—Yellow mustard. (Fig. 31.)
[Illustration: FIG. 31.—White mustard (_Sinapis alba_ L.).]
=Range and habitat.=—White mustard is a weed found in cultivated land
along waysides and fence rows, but is not so abundant nor so widely
distributed as the black mustard. It is naturalized in this country
from Europe.
=Description.=—This plant is very similar to black mustard, but is
smaller (growing only about 1 to 2 feet tall), bright green, but the
flowers and seeds are much larger, and the rough-hairy pods with their
long, sickle-shaped beaks are spreading instead of being pressed
against the stem. The flowers are paler yellow than those of the
fore-going species. The divisions of the leaves reach to the midrib,
the leaves are rough-hairy, and the pods bristly. The seeds are pale
yellow and smooth.
=Collection and uses of seeds.=—The seeds are to be collected in the
same manner as those of black mustard. White mustard seed has no odor
in its entire state, and when water is added in grinding it the odor
does not become so pronounced as in the case of black mustard, neither
is the taste so pungent.
In medicine mustard seeds are used principally in the preparation of
plasters and poultices. They are used also in dyspepsia, and in large
doses act as an emetic.
=Imports and prices.=—The imports into the United States of black and
white mustard together during the fiscal year ended June 30, 1903,
amounted to 5,302,876 pounds. The price ranges from 3 to 6 cents per
pound for both the black and white mustard seeds.
