E.—55. + + WEEDS USED IN MEDICINE. + + + + + INTRODUCTION. + + +It is a matter of interest, primarily to the farmer, that certain of +the well-known weeds now either generally or locally infesting the +country are the sources of crude drugs at the present time obtained +wholly or in part by importation from abroad. Roots, leaves, and +flowers of several of the species most detrimental in the United States +are gathered, prepared, and cured in Europe, and not only form useful +commodities there but supply to a considerable extent the demands of +foreign lands. Hence it appears probable that while weeds can hardly +be made desirable, still in his fight to exterminate them the farmer +may be able to turn some of them to account. Some of the plants +coming within this class are in many States at present subject to +antiweed laws and farmers are required to take measures toward their +extermination. It seems, therefore, desirable to make these pests +sources of profit where possible. In many cases, when weeds have been +dug, the work of handling and curing them is not excessive and can +readily be done by women and children. + +The prices paid for crude drugs from these sources are not great and +would rarely tempt anyone to pursue this line of work as a business. +Yet, if in ridding the farm of weeds and thus raising the value of the +land the farmer can at the same time make these pests the source of a +small income instead of a dead loss, something is gained. + +In order to help the farmer to obtain the best possible prices for such +products, instructions for collecting and preparing crude drugs derived +from weeds are here briefly given. The collector should observe them +carefully. + + + + + COLLECTION AND CURING OF DRUGS. + + +Too much emphasis can not be placed upon the importance of carefully +and thoroughly drying all crude drugs, whether roots, herbs, leaves, +barks, flowers, or seeds. If insufficiently dried, they will heat +and become moldy in shipping, and the collector will find his goods +rejected by the drug dealer and have all his trouble for nothing. + +Another important matter to be considered in collecting drugs for +market is freedom from foreign substances. All drugs should be clean +and wholesome looking and contain no admixture of fragments of other +plants, stones, dirt, or other impurities. A bright natural color is +extremely desirable in leaves, herbs, and flowers, and adds much to +the salability of the product. This can be readily brought about by +giving careful attention to proper drying in the shade (not in direct +sunlight), and by protection from dew or rain by placing the drugs +under cover at nightfall or whenever necessary. Roots may be cleaned by +washing, but leaves, herbs, and flowers should never be washed. + +It is important also to collect drugs in proper season only. Neglect in +this respect will bring nothing but disappointment to the gatherer, as +drugs collected out of season not only are not acceptable to the dealer +on account of inferior medicinal qualities, but there will also be, in +the case of roots, a greater amount of shrinkage in a root dug during +the growing season than will take place when it is collected after +growth has ceased. + +The collector should be sure that the plant he is collecting is the +right one. There are many plants that closely resemble one another, +yet one may possess medicinal properties and the other be absolutely +useless. Again, a plant may contain very poisonous principles, and if +represented to be something else, it might of course do untold injury. +It would therefore be best, where any doubt exists, to send a specimen +of the entire plant, including leaves, flowers, and fruits, to a drug +dealer or to the nearest State experiment station for identification. + + + ROOTS. + +Roots should never be collected during the growing season, as at that +time they are deficient in medicinal properties, and they also shrink +more in drying and weigh less than when gathered at full maturity. + +The roots of annual plants should be dug just before the flowering +period, and those of biennial or perennial plants after the tops have +dried, the former in the autumn of the first year and the latter in the +fall of the second or third year. + +After the roots have been dug the adherent soil should be well +shaken from them, and all foreign particles, such as stones, dirt, +roots and parts of other plants, should be removed. If the roots +can not be sufficiently cleared of soil by shaking, they should be +thoroughly washed in clean water. It does not pay to be careless in +this matter. The presence of soil increases the weight of the roots, +but the intending purchaser is not willing to pay for the weight of +the dirt, and grades the uncleaned drug accordingly. It is the clean, +bright-looking root that will bring a good price. + +After washing, the roots should be carefully dried. This can best be +accomplished by exposing them to light and air (not direct sunlight) on +racks or shelves, or on clean, well-ventilated barn floors or lofts. +They should be spread out thinly and turned occasionally from day to +day until completely cured. When this point is reached, in perhaps +three to six weeks, the roots will snap readily when bent. During the +curing process the roots, if dried out of doors, should be placed under +shelter at night and upon the approach of rainy weather. + +With some roots additional preparation is required, such as slicing and +the removal of fibrous rootlets. Wherever this is necessary mention +will be made of it under the descriptions of the different plants. In +general, it may be said that large roots should always be split or +sliced when green in order to facilitate drying. + + + BARKS. + +The plants considered in this bulletin do not furnish medicinal barks, +but inasmuch as there are certain sections of the country where trees +furnishing such barks are rather abundant, directions for their +collection may not be out of place here. + +Barks of trees should be gathered in spring, when the sap begins to +flow, but may also be peeled in winter. In the case of the coarser +barks (as elm, hemlock, poplar, oak, pine, and wild cherry) the outer +layer is shaved off before the bark is removed from the tree, which +process is known as “rossing.” Only the inner bark of these trees is +used medicinally. Barks may also be cured by exposure to sunlight. +Moisture must be avoided. + + + LEAVES AND HERBS. + +Leaves and herbs should be collected when the plants are in full +flower. It is very desirable that they retain their bright green color +after curing, and this can be done by careful drying in the shade. In +the collection of leaves the whole plant may be cut and the leaves +may be stripped from it, rejecting the stems as much as possible. In +the case of herbs the coarse and large stems should be rejected and +only the flowering tops and more tender stems and leaves included. All +grasses, bits of other plants, and other foreign substances should be +carefully removed, as well as dead, shriveled, diseased, and discolored +specimens. + +Both leaves and herbs should be spread out in thin layers on clean +floors, racks or shelves, in the shade but where there is free +circulation of air, and turned frequently until thoroughly dry. +Moisture will darken them. The same precautions that are necessary in +curing roots apply here also, so far as placing them under cover to +avoid dew or rain is concerned. + + + FLOWERS. + +Flowers are collected when they first open or immediately after—not +when they are beginning to fade. To preserve the bright natural color +as nearly as possible they should be carefully dried in the shade, in +the same manner as directed for leaves and herbs. + + + SEEDS. + +Seeds should be gathered just as they are ripening, before the seed +pods open, and should be winnowed in order to remove fragments of +stems, leaves, and shriveled specimens. + + + + + DISPOSAL OF THE DRUGS. + + +Samples representative of the lot of drugs to be sold should be sent +to the nearest commission merchant, general store, or drug store, +for inspection and for quotation on the amount of drug that can be +furnished, or for information as to where to send the article. The +size of the sample depends, of course, upon the kind of drug; from +3 to 4 ounces—or, say, at least a good handful—should be submitted. +The package containing the sample should be plainly marked as regards +contents, and the name and address of the sender given. In writing to +the different dealers for information and prices, it should be stated +how large a quantity of a particular drug can be furnished and how +soon this can be supplied, and postage should always be inclosed for +reply. In no case should the entire lot of collected drugs be sent to +dealers without preliminary correspondence. The collector should bear +in mind that freight is an important item, and it is best, therefore, +to address such dealers as are nearest to the place of production. When +ready for shipment, crude drugs may be tightly packed in burlap or +gunny sacks, or in dry, clean barrels. + + + + + DESCRIPTIONS OF PLANTS. + + +The plants included in this bulletin are burdock, dandelion, the docks, +couch grass, and pokeweed (principally root drugs); foxglove, mullein, +lobelia, tansy, gum plant, scaly grindelia, boneset, catnip, hoarhound, +yarrow, fleabane, blessed thistle, jimson weed, and poison hemlock (of +which either the leaves, flowers, herb, or seeds are used in medicine); +and also wormseed, and black and white mustards, of which the seeds +only are used. + +Descriptions of these plants follow, together with the common names +by which they are known in different localities, the habitat (or, in +other words, the kinds of places or soils in which they are likely to +be found), their geographical range, information as to the parts to be +collected, their uses, the extent to which they are imported and the +prices usually paid by dealers. + +The principal uses for which these plants are employed in medicine are +briefly indicated, but none of the drugs mentioned should be taken +without the advice of a physician. + +With the exception of the figures for dandelion and mustard, which were +obtained from the Bureau of Statistics of the Department of Commerce +and Labor, the imports are based on estimates furnished by dealers, +and the prices per pound, while serving to give an idea as to what +may be expected for the drugs, will vary from year to year, depending +principally upon supply and demand. + +There are of course a large number of plants used in medicine that are +not included in this bulletin, which is intended to cover only such +medicinal plants as may be classed as weeds. + + + BURDOCK. + _Arctium lappa_ L. + +=Other common names.=—Cockle button, cuckold dock, beggars’ buttons, +hurr-bur, stick button, hardock, and bardane. (Fig. 1.) + +[Illustration: FIG. 1.—Burdock (_Arctium lappa_ L.). Flowering plant.] + +=Habitat and range.=—Burdock is one of the most common weeds. It was +introduced from the Old World, and is common and often very abundant in +the Eastern and Central States and in some scattered localities in the +West, growing along roadsides, in fields, pastures, and waste places. + +=Description.=—This is a coarse, unsightly biennial weed of the aster +family (Asteraceæ), which produces during the first year of its growth +only a rosette of large, thin leaves (fig. 2) and a long, tapering +root having a diameter of from one-half to 1 inch. When full grown it +measures from 3 to 7 feet high. The round, fleshy stem is branched, +grooved, and hairy, with very large leaves, even in the early stages +of the growth of the plant, the lower leaves often measuring 18 inches +in length. The leaves are alternate, on long, solid, deeply furrowed +leafstalks; thin, roundish or oval, but usually heart-shaped; with +even, wavy, or toothed margins; smooth above, and pale and woolly on +the under surface. The flowers are purple, in small, clustered heads, +appearing in the second year, from July to frost. These flower heads +are armed with hooked tips, and the burs thus formed are a great pest, +attaching themselves to clothing and to the wool and hair of animals. +The seed of burdock is produced in great abundance, one plant bearing +as many as 400,000 seeds. + +=Parts used.=—The root alone is recognized in the United States +Pharmacopœia, but there is a limited demand for burdock seed, and the +leaves also are employed. Burdock roots and seeds are used in blood +and skin diseases, and the leaves externally as a cooling poultice for +swellings and ulcers, the latter being employed only in the fresh state. + +[Illustration: FIG. 2.—Burdock. First year’s growth.] + +Burdock has a large taproot, about 12 inches long, fleshy, the outside +blackish-brown or grayish-brown, the inside light in color and spongy +in the center. It is to be collected in the fall of the first year. The +roots must be washed, split lengthwise, and carefully dried. Drying +causes the root to lose about four-fifths of its weight, and to become +scaly, and wrinkled lengthwise. Sometimes the bases of the leafstalks +remain at the top of the root in the form of a small, white, silky +tuft. The odor of the root is weak and unpleasant. + +The seeds are oblong, curved, flattened, and angular, dark brown +and sometimes spotted with black, and have no odor. These should be +collected when ripe or nearly so. + +=Imports and prices.=—About 50,000 pounds of lappa or burdock root are +imported annually, and the best root is said to come from Belgium, +where great care is exercised in its collection. + +The price of the root ranges from 3 to 8 cents per pound, and that of +the seed from 5 to 10 cents. + + + DANDELION. + _Taraxacum taraxacum_ (L.) Karst. (_Taraxacum officinale_ Weber.) + +[Illustration: FIG. 3.—Dandelion (_Taraxacum taraxacum_ (L.) Karst). +(An unusually fibrous root.)] + +=Other common names.=—Blow-ball, cankerwort, doon-head-clock, +fortune-teller, horse gowan, Irish daisy, yellow gowan, one o’clock. +(Fig. 3.) + +=Range and habitat.=—Dandelion is distributed as a weed in all +civilized parts of the world, and in this country is naturalized from +Europe. With the exception of the South, it is very abundant throughout +the United States in fields and waste places, and it is especially +troublesome in lawns and meadows. + +[Illustration: FIG. 4.—Dandelion root, 16 inches long.] + +=Description.=—The dandelion is so well known a weed, especially in +lawns, that it scarcely requires a description, almost everyone being +familiar with its rosette of coarsely toothed leaves, golden-yellow +flowers, and round fluffy seed heads. It is a perennial plant of the +chicory family (Cichoriaceæ), and it may be said to be in flower +throughout almost the entire year. In spring the young leaves are +collected and used for greens or salad, but the part employed in +medicine is the root. The flowering stem of the dandelion is usually +longer than the smooth, shining green, coarsely toothed leaves, +reaching a height of from 5 to 10 inches. It is erect, smooth, naked, +and hollow, bearing at the summit a solitary yellow flower head, +which opens in the morning and only in fair weather. The entire plant +contains a white, milky juice. + +=Part used.=—As already stated, the root of dandelion is used +medicinally. It is a large taproot, sometimes 20 inches long, thick +and fleshy, dull-yellow or brownish on the outside, white inside, +practically without odor, and bitter. (Fig. 4.) Dandelion is often used +as a tonic in diseases of the liver and in dyspepsia. + +The best time for digging dandelion root is from July to September, +during which time the milky juice becomes thicker and the bitterness +increases. It should be carefully washed and thoroughly dried. +Dandelion roots decrease considerably in size by drying, weighing less +than half as much as the fresh roots and becoming wrinkled lengthwise. +The dried root should not be kept too long, as drying diminishes its +medicinal virtues. + +=Imports and prices.=—During the fiscal year ended June 30, 1903, the +imports of taraxacum or dandelion root into the United States amounted +to 115,522 pounds. The price per pound ranges from 4 to 6 cents. + + + DOCKS. + _Rumex_ species. + +Several species of docks possess medicinal properties. Among these +are the yellow dock (_Rumex crispus_ L.), the broad-leaved dock (_R. +obtusifolius_ L.), and the yellow-rooted water dock (_R. britannica_ +L.), all more or less abundant throughout the United States. Other +species are also recognized as possessing value in medicine, but those +above mentioned are the kinds generally collected. + + + Yellow Dock. + _Rumex crispus_ L. + +=Other common names.=—Curled dock, narrow dock, sour dock. (Fig. 5.) + +[Illustration: FIG. 5.—Yellow dock (_Rumex crispus_ L.). First year’s +growth.] + +=Range and habitat.=—The species most commonly employed in medicine +is the yellow dock, a perennial introduced from Europe and now found +throughout the United States as a troublesome and very persistent weed +in cultivated as well as waste ground, among rubbish heaps, and along +roadsides. + +=Description.=—The deep, spindle-shaped root sends up an erect, +angular, and furrowed stem about 2 to 4 feet high, leafy, branching +near the top, and bearing numerous elongated clusters of inconspicuous +flowers. The leaves are lance-shaped, acute, with the margins strongly +waved and crisped. The lower leaves are obtuse or heart shaped at the +base, from 6 to 8 inches in length, and are borne on long stalks, while +those nearer the top are narrower and shorter, being only 3 to 6 inches +long, on short stems or stemless. + +From June to August the yellow dock puts forth, interspersed with +leaves, its many long dense clusters of green, drooping groups of +inconspicuous flowers placed in circles around the stem. + + + Broad-leaved Dock. + _Rumex obtusifolius_ L. + +=Other common names.=—Bitter dock, common dock, blunt-leaved dock, +butter dock. (Fig. 6.) + +[Illustration: FIG. 6.—Broad-leaved dock (_Rumex obtusifolius_ L.). +First year’s growth.] + +=Range and habitat.=—The range of this very common weed extends from +the New England States to Oregon and south to Florida and Texas; it +occurs in waste places. + +=Description.=—Broad-leaved dock differs from the yellow dock +principally in its more robust habit of growth. It grows to about the +same height, but its stem is stouter, and the leaves, which are wavy +along the margin as in the yellow dock, are much broader and longer. +The lower leaves have long stalks, and are from 6 to 14 inches in +length, with heart-shaped or roundish bases, while the upper ones are +from 2 to 6 inches long and are on short stalks. + +[Illustration: FIG. 7.—Leaf, fruiting spike, and root of broad-leaved +dock.] + +The green flowers appear from June to August, and are in rather long, +open clusters, the groups rather loose and far apart. In all of the +docks here mentioned, the three inner divisions of the calyx (outer +covering of flower) in fruiting form a kind of triangular nut, like the +grain of buckwheat (to which family, Polygonaceæ, the docks belong), +and one or more of these divisions bear on the back a small granule. +The difference between flower and fruit is barely distinguishable when +seen from a little distance so long as the fruit is immature, both +being green, but later in the season, as the fruit ripens, the spikes +take on a rusty-brown color. (Fig. 7.) + + + Yellow-rooted Water Dock. + _Rumex britannica_ L. + +=Habitat and range.=—As the common name indicates, this plant frequents +swampy and wet places and banks of streams. It is found from Canada to +New Jersey and Pennsylvania, and westward to Minnesota, Illinois, and +Iowa. + +=Description.=—The yellow-rooted water dock is a taller plant than +either of the docks previously mentioned, its stout stem sometimes +reaching a height of 6 feet. The leaves at the base of the plant are +borne on long stalks, and are from 1 to 2 feet in length, but, as with +the other two species, the leaves toward the top of the plant are +shorter, as are also the stalks supporting them. The densely flowered +clusters are not as leafy as in the preceding species mentioned. The +plant flowers from July to August. + +[Illustration: FIG. 8.—Yellow dock root.] + + + Dock Roots. + +The root, which is the part to be collected for medicinal purposes, is +very similar in all of these species of dock (figs. 7 and 8), usually +from 8 to 12 inches long, fleshy, often somewhat branched, the outside +dark reddish-brown with a rather thick bark, internally yellowish. It +possesses but a very faint odor and a bitter, astringent taste. The +roots should be collected in late summer or autumn after the fruiting +tops have ripened, then washed, split lengthwise into halves or +quarters, and carefully dried. + +The docks are largely employed for purifying the blood and as a remedy +in skin diseases. + +=Imports and prices.=—Rumex or dock roots are imported into this +country to the extent of about 125,000 pounds annually. The price +ranges from 2 to 8 cents per pound. + + + COUCH GRASS. + _Agropyron repens_ (L.) Beauv. (_Triticum repens_ L.) + +=Other common names.=—Dog-grass, quick-grass, quack-grass, +quitch-grass, scutch-grass, twitch-grass, witch-grass, wheat-grass, +Chandler’s grass, creeping wheat-grass, devil’s-grass, durfa-grass, +Durfee-grass, Dutch-grass, Fin’s grass, quake-grass. (Fig. 9.) + +=Range and habitat.=—Couch grass, like so many other pernicious +weeds, was introduced into this country from Europe, and is now a +most troublesome pest in cultivated ground, causing the farmer a +loss of thousands of dollars annually by taking possession of fields +and crowding out valuable crops. It is most abundant from Maine to +Maryland, and westward to Minnesota and Missouri, but is rather +sparingly distributed in the South. It is gaining ground on farms on +the Pacific slope. + +[Illustration: FIG. 9.—Couch grass (_Agropyron repens_ (L.) Beauv.).] + +=Description.=—This rather coarse grass produces several stems, 1 +to 3 feet high, from a long, creeping, jointed rootstock, and bears +densely flowered spike-like heads resembling those of rye or beardless +wheat. The stems are round, smooth, thickened at the joints, and +hollow, bearing from five to seven leaves. These have a long cleft +sheath, and are rough on the upper surface. The heads or spikes are +terminal, solitary, compressed, with two rows of spikelets on a wavy +and flattened axis. + +Couch grass is one of the most difficult weeds to eradicate, on +account of the long jointed rootstock, each joint of which is capable +of producing a new plant. Every bit of the rootstock must therefore be +removed from the soil or killed in order to eradicate it. + +=Part used.=—The most important part of this grass, not only +agriculturally but also pharmaceutically, is its long, tough rhizome or +rootstock, creeping along underneath the ground and pushing in every +direction. It is pale yellow, smooth, about one-eighth of an inch in +diameter, with joints at intervals of about an inch from which slender +branching rootlets are produced. + +One of the best methods of destroying this weed is to plow up the roots +and burn them. They need not be burned, however, but may be saved and +prepared for the drug market. After the rootstocks have been collected +and washed the rootlets should be removed and the rhizome or rootstock +(not the rootlets) cut into short pieces about two-fifths of an inch +long. An ordinary feed-cutting machine may be used for this purpose. +These should then be dried as suggested in the general instructions. + +In the drug trade this plant is generally known as dog grass or +triticum. As found in the stores, it is in the form of small, angular +pieces, about one-eighth to one-fourth of an inch long, straw colored, +shining, and hollow. These pieces are odorless but have a somewhat +sweetish taste. + +The fluid extract prepared from dog grass is used in kidney and bladder +troubles. + +=Imports and prices.=—Couch grass is almost wholly an imported article, +some 250,000 pounds coming into this country annually from Europe. The +price is about 3 to 7 cents per pound. + + + POKEWEED. + _Phytolacca americana_ L. (_Phytolacca decandra_ L.) + +=Other common names.=—Poke, pigeon-berry, garget, scoke, pocan, coakum, +Virginian poke, ink-berry, red-ink-berry, American nightshade, cancer +jalap, redweed. (Fig. 10.) + +=Range and habitat.=—Pokeweed is common in rich, moist soil along fence +rows, margins of fields, and in uncultivated land from the New England +States to Minnesota and south to Florida and Texas. It is native in +this country and naturalized in Europe, where it is regarded as an +ornamental garden plant. + +=Description.=—The reddish purple stems, rich green foliage, and +clusters of white flowers and dark-purple berries give to this plant a +rather handsome appearance. Pokeweed attains a height of from 3 to 9 +feet from a very large perennial root. It is erect, branched, the stems +stout, smooth, green at first, then reddish. On examining a piece of +the stem, the pith will be seen to be divided into disk-shaped pieces, +with hollow spaces between them. The leaves are ovate or ovate-oblong, +acute at the apex, smooth, about 5 inches long and 2 to 3 inches wide, +on short stems. The margins are without indentation. About July to +September the long clusters of whitish flowers are produced, followed +by the green berries, which upon ripening become a rich dark-purple +color. The flower clusters are from 3 to 4 inches in length and on long +stalks, the flowers numerous and borne on reddish stems. The berries +are globular, flattened both at top and bottom, smooth and shining, and +contain ten black seeds imbedded in a rich crimson juice. (Fig. 11.) + +[Illustration: FIG. 10.—Pokeweed (_Phytolacca americana_ L.).] + +=Parts used.=—For medicinal purposes the berries and roots are +employed. Both of these should be collected when the berries are fully +mature, which usually occurs about two months after flowering. The +clusters of berries should be carefully dried in the shade. They are +poisonous, have no odor, a sweetish taste at first, then acrid. + +[Illustration: FIG. 11.—Pokeweed, flowering and fruiting branch.] + +[Illustration: FIG. 12.—Pokeroot.] + +Pokeweed has a very large, fleshy, and poisonous root, conical in shape +and branched. (Fig. 12.) It should be gathered in the latter part of +the fall, thoroughly cleaned, cut into transverse slices, and carefully +dried. When dry it has a grayish, wrinkled appearance, breaks with a +fibrous fracture, and the slices show many concentric rings. There is a +slight odor and the taste is sweetish and acrid. + +Both the berries and roots are alterative, act upon the bowels and +cause vomiting, and preparations made from them are used in treating +various diseases of the skin and blood, and in certain cases in +relieving pain and allaying inflammation. + +=Price.=—Phytolacca or pokeroot brings from 2 to 5 cents per pound, and +the dry berries about 5 cents per pound. + + + FOXGLOVE. + _Digitalis purpurea_ L. + +=Other common names.=—Purple foxglove, thimbles, fairy cap, fairy +fingers, fairy thimbles, fairy bells, dog’s finger, finger flower, +lady’s glove, ladyfingers, lady’s thimble, popdock, flapdock, flopdock, +lion’s mouth, rabbit’s flower, cottagers, throatwort, Scotch mercury. +(Fig. 13.) + +[Illustration: FIG. 13.—Foxglove (_Digitalis purpurea_ L.).] + +=Range and habitat.=—Foxglove was originally introduced into this +country from Europe as an ornamental garden plant, but has now escaped +from cultivation in a few localities and is assuming the character +of a weed. This is the case in parts of Oregon, Washington, and West +Virginia, where the plant is found in great abundance in dry, sandy +soil, along roads and fence rows, on the borders of timber land, and in +small cleared places. + +=Description.=—This is a very handsome plant of the figwort family +(Scrophulariaceæ), biennial, and the first year forms only a rosette +of dense leaves, but in the second year of its growth the simple erect +flowering stalk is produced, attaining a height of from 3 to 4 feet. +This is round, indistinctly angled toward the top, leafy and downy. The +leaves are oblong-ovate, narrowed at the base into long winged stalks; +the upper surface of the leaves is dull-green and wrinkled, while the +under side is grayish, with short, soft hairs and a thick network of +prominent veins. The root leaves are rather large and are borne on long +stalks, but as the leaves approach the top of the plant they become +smaller and the leafstalks shorter. + +The plant is in flower about June, and the long clusters of numerous +tubular bell-shaped flowers are very showy. The clusters are terminal, +and about 14 inches in length. The flowers are large, about 2 inches +long, the color ranging from white through lavender to purple, the +inside of the lower lobe bearing long, soft, white hairs and crimson +spots on a white ground. + +=Part used.=—Leaves of the second year’s growth only are employed, and +these should be collected when about two-thirds of the flowers have +expanded. They should be very carefully dried in the shade and then +kept in closed boxes or barrels so as to keep out all moisture. The +greatest care is necessary in curing, as the leaves soon lose their +medicinal properties if not properly dried. + +Preparations made from foxglove are of great value in heart troubles, +but they are poisonous and should never be used except on the advice of +a physician. + +=Imports and prices.=—From 40,000 to 60,000 pounds of digitalis or +foxglove are annually imported into this country from Europe, where the +plant is cultivated. The American-grown product has so far never been +used, but leaves from the wild American plant have been assayed and +found to be equally as good as the European article. + +The price per pound ranges from about 6 to 8 cents. + + + MULLEIN. + _Verbascum thapsus_ L. + +=Other common names.=—Great mullein, velvet or mullein dock, Aaron’s +rod, Adam’s flannel, blanket leaf, bullock’s lungwort, cow’s or clown’s +lungwort, candlewick, feltwort, flannel leaf, old-man’s flannel, hare’s +beard, hedge taper, ice leaf, Jacob’s staff, Jupiter’s staff, lady’s +foxglove, Peter’s staff, shepherd’s club, torches, torchwort, velvet +plant. (Fig. 14.) + +=Range and habitat.=—Mullein is a native of Europe, and occurs in this +country as a troublesome weed in fields and pastures, waste places, +and along roadsides from Maine to Minnesota and southward, and it is +also spreading in the far Western States. It produces great quantities +of seed, and, if allowed to persist, will soon stock the ground with +seeds which may retain their vitality and germinate at intervals for a +number of years. + +[Illustration: FIG. 14.—Mullein (_Verbascum thapsus_ L.).] + +=Description.=—Mullein can be easily recognized by its tall, erect +habit of growth, the white-woolly or felty appearance of the entire +plant, and its spike of golden-yellow flowers. It is a biennial +belonging to the figwort family (Scrophulariaceæ). + +This plant has a stout, straight stem, which sometimes grows as tall +as 7 feet. The stem and also the leaves are densely hairy, the latter +alternate, sessile (stemless), their margins extending in wings along +down the stem. The rather thick, rough leaves are from 4 to 12 inches +in length, oblong, acute, and densely hairy above and below. + +In the first year of its growth only a rosette of downy leaves is +produced, but during the second year the flower stalk with its densely +flowered spike appears. The golden-yellow flowers are produced from +June to August. + +=Parts used.=—As the leaves and flowers are to be collected at the +time when the plant is in bloom, the propagation of the plant by the +dissemination of its seed is prevented. The leaves are cured in the +usual manner. They are practically inodorous, and have a somewhat +bitter, mucilaginous taste. + +It is very desirable to have the flowers retain their bright yellow +color: they must therefore be thoroughly dried, and then kept free from +moisture in well-stoppered bottles. They readily absorb moisture and +if allowed to become damp will turn black. The corolla (petals), with +the adhering stamens only, is dried, the calyx being rejected. Mullein +flowers have a sweetish, pleasant odor. + +Mullein is used in coughs and catarrh, to quiet nervous irritation, +and to relieve pain and inflammation. According to some authors the +dried leaves are often smoked like tobacco to relieve nasal catarrh and +throat affections. + +=Imports and prices.=—About 5,000 pounds of verbascum or mullein +flowers are annually imported, chiefly from Germany, in which country +this plant is cultivated. The leaves are also imported to a small +extent. + +The price paid for the leaves ranges from 2½ to 5 cents per pound, and +that for the flowers may range from 25 to 75 cents per pound. + + + LOBELIA. + _Lobelia inflata_ L. + +[Illustration: FIG. 15.—Lobelia (_Lobelia inflata_ L.).] + +=Other common names.=—Indian tobacco, wild tobacco, bladder pod, asthma +weed, gagroot, pukeweed, vomitwort, low belia, eyebright. (Fig. 15.) + +=Range and habitat.=—This poisonous weed occurs nearly everywhere +throughout the United States, being most plentiful east of the +Mississippi River, and thriving in dry, clayey, or siliceous soil in +sunny situations along roadsides, and in old fields and pastures. + +=Description.=—The erect leafy stem of this annual herbaceous plant +is from 1 to 3 feet high, from a fibrous root. It is simple and +rough-hairy below, smooth above, and bears a few short branches. +The entire plant contains an acrid milky juice. It belongs to the +bellflower family (Campanulaceæ). + +The pale-green leaves are alternate, from 1 to 2½ inches long, +gradually diminishing in size as they reach the summit of the plant, +the lower leaves being borne on stalks, while the upper ones are +stemless. They are thin, oblong or oval, blunt, irregularly toothed, +and almost wavy, with short hairs on both surfaces. + +From July until frost the rather inconspicuous, very small pale-blue +flowers appear. These are very numerous, each one borne in the axils +of the upper leaves on very short stems, all together forming a long, +spike-like head. The lower lip of the flower has three lobes, the upper +one two segments, and from the center of the latter the tube of the +flower is cleft to the base. The seed pods are in the form of inflated +capsules, nearly globular, striated (grooved or marked with parallel +lines), and contain very numerous minute dark-brown seeds. + +=Parts used.=—The leaves and flowering tops are used in medicine, and +there is also a good demand for the seed. The leaves and tops should be +gathered after some of the pods have become inflated, should be dried +in the shade, and when dry kept in covered vessels. The dried leaves +and tops have a rather disagreeable, somewhat sickening odor, and the +taste, though mild at first, soon becomes strongly acrid and nauseous. +The seeds are extremely minute, and each capsule is said to contain +from 450 to 500 seeds. + +Lobelia is an expectorant, acts upon the nervous system and bowels, +causes vomiting, and is poisonous. + +=Price.=—The price paid for the dried leaves and tops ranges from 3 to +8 cents per pound, and that for the seed from 15 to 20 cents per pound. + + + TANSY. + _Tanacetum vulgare_ L. + +=Other common names.=—Bitter buttons, ginger plant, parsley fern, +scented fern. (Fig. 16.) + +=Range and habitat.=—Tansy was originally introduced into this country +as a garden plant from Europe, where it is native. It has now escaped +from cultivation and is found as a weed along waysides and fences +in many places from New England to Minnesota and southward to North +Carolina and Missouri. + +=Description.=—This strong-scented perennial herb belongs to the aster +family (Asteraceæ). The stout, erect stem is from 1½ to 3 feet high, +branching near the top, somewhat reddish, and usually smooth. The +general outline of the leaf is oval, and it is divided nearly to the +midrib into about seven pairs of segments, which, like the terminal +one, are again divided for about two-thirds of the distance to the +midvein into smaller lobes having saw-toothed margins. The entire leaf +is about 6 inches in length. + +Tansy is in flower from July to September, and the roundish but +flat-topped yellow flower heads are produced in dense terminal clusters. + +=Parts used.=—At the time of flowering the leaves and tops are +collected for medicinal purposes and are dried in the usual manner. The +odor of tansy is strongly aromatic and the taste bitter. In drying, +tansy loses about four-fifths of its weight. + +Tansy is employed in derangements of women, and has stimulant and tonic +properties. It is also used for expelling worms. This drug is poisonous +and has been known to produce fatal results. + +[Illustration: FIG. 16.—Tansy (_Tanacetum vulgare_ L.).] + +[Illustration: FIG. 17.—Gum plant (_Grindelia robusta_ Nutt.).] + +=Imports and prices.=—About 30,000 pounds of tanacetum or tansy are +imported annually. The price paid per pound ranges from 3 to 6 cents. + + + GUM PLANT. + _Grindelia robusta_ Nutt. + +=Range.=—The gum plant (fig. 17) occurs in the States west of the Rocky +Mountains. + +=Description.=—The entire plant is covered with a resinous substance, +which gives it a gummy, varnished appearance, whence its common name, +gum plant, is derived. + +This perennial of the aster family of plants has an erect habit of +growth, and sends up a round, smooth stem about a foot and a half +high, narrowly grooved and freely branching near the top, each branch +terminating in a large yellow flower. The branches near the flower +heads have a slightly reddish appearance. + +The pale-green leaves are about an inch long, of a leathery texture, +rather rigid, coated with resin, and show numerous translucent dots. +The leaves are oblong-spatulate (having a gradually narrowed base below +the broader rounded summit) and are more or less clasping at the base, +the lower ones somewhat saw-toothed. + +The yellow flowers are borne singly at the ends of the branches and +measure about three-quarters of an inch across. The involucre (set +of small leaves immediately beneath the flower) is very resinous and +consists of numerous thick, overlapping scales, the tips of which are +rolled forward. + +=Parts used and prices.=—The flowering tops and leaves of this and of +the scaly grindelia are collected indiscriminately, and bring from 5 to +12 cents per pound. + +They are used in asthma and similar affections, and externally in cases +of poisoning by poison ivy. + + + SCALY GRINDELIA. + _Grindelia squarrosa_ (Pursh) Dunal. + +[Illustration: FIG. 18.—Scaly grindelia (_Grindelia squarrosa_ (Pursh) +Dunal).] + +=Range.=—Scaly grindelia (fig. 18) has a wider distribution than the +gum plant, being quite common on the plains and prairies from the +Saskatchewan to Minnesota, south to Texas and Mexico, and westward to +California. + +=Description.=—This species is very similar to the gum plant, with the +exception that it is smaller and does not have the gummy appearance +of the former. The slender, erect stems are from 1 to 2 feet high and +somewhat sparingly branched near the top. The branches near the flower +heads appear to be somewhat more reddish than in the species previously +mentioned. In this species, also, the leaves are not borne on stalks, +but are somewhat clasping at the base, and they are longer (about +2 inches long), not rigid, thinner, and more prominently toothed. +The flowers are also very similar to those of the gum plant, but are +smaller, the scales narrower, and the recurved tips longer and more +slender. + +=Parts used.=—The leaves and flowering tops are collected with those of +the gum plant, _Grindelia robusta_. + + + BONESET. + _Eupatorium perfoliatum_ L. + +[Illustration: FIG. 19.—Boneset (_Eupatorium perfoliatum_ L.).] + +=Other common names.=—Thoroughwort, crosswort, wood boneset, teasel, +ague-weed, feverwort, thorough-stem or thorough-wax, vegetable +antimony, sweating plant, Indian sage, wild sage, tearal, wild Isaac. +(Fig. 19.) + +=Range and habitat.=—Boneset delights in moist situations, and is +common as a weed in clayey or sandy soil, in low, wet ground, and along +streams, on the edges of swamps and in thickets from the New England +States west to Nebraska and south to Texas and Florida. + +=Description.=—One of the features which will aid in recognizing this +plant is the peculiar arrangement of the leaves. These are opposite +each other and joined together at the base around the stem, and +therefore have the appearance of a single leaf with the stem passing +through the center of it. + +Boneset is a perennial herb of the aster family of plants (Asteraceæ), +with stout, rough, hairy stems 1 to 5 feet high, from a horizontal, +crooked root. The leaves are opposite, united at the base, lance +shaped, tapering to a point, bluntly toothed, rough with prominent +veins, wrinkled, dark green on the upper surface, downy and paler green +on the lower surface. Both leaves together measure from 8 to 14 inches +from point to point and 1 to 1½ inches wide. The flowers are white, +tubular, ten to twenty or more united in dense heads, and the heads are +borne in rather crowded flat-topped clusters, appearing from July to +September. + +=Parts used.=—The leaves and flowering tops are the parts used in +medicine, and these should be collected when the plants are in +flower, stripped from the stalk, and carefully dried. They lose about +three-fourths of their weight in drying. The odor is faintly aromatic, +the taste bitter and astringent. + +As indicated by the common names “ague-weed” and “feverwort,” this is a +popular remedy in fever and ague. It is used also in colds, dyspepsia, +jaundice, and for toning up the system. In large doses it is an emetic +and cathartic. + +=Prices.=—Eupatorium or boneset leaves and tops bring from 2 to 8 cents +per pound. + + + CATNIP. + _Nepeta cataria_ L. + +=Other common names.=—Catmint, catrup, cat’s wort, field mint. (Fig. +20.) + +=Range and habitat.=—This very common weed is naturalized from Europe, +and is found in rather dry soil in waste places and cultivated land, +about old buildings and along fences, from Canada to Minnesota and +southward to Virginia and Arkansas. + +=Description.=—The erect, square stems of this perennial herb of the +mint family (Menthaceæ) grow to a height of 2 to 3 feet, are branched, +and somewhat whitish in appearance from the covering of fine white +hairs. + +[Illustration: FIG. 20.—Catnip (_Nepeta cataria_ L.)] + +The leaves are opposite and borne on stems, heart shaped or oblong, +with an acute apex, 1 to 2½ inches long, evenly and finely scalloped, +green above, beneath grayish-green with fine white hairs. The +many-flowered clusters appear from June to September, and are borne in +thick spikes 1 to 5 inches long at the top of the stems and branches. +The flowers are white or somewhat purple, two-lipped, the upper lip +two-cleft, the lower one three-lobed and sometimes spotted with red, +the middle lobe broadest and round-toothed. + +=Parts used.=—The flowering tops and leaves are to be collected +when the plant is in flower and carefully dried. They have a strong +mint-like odor and a bitter taste. The coarser stems and branches +should be rejected. + +Catnip is used in derangements of women, as a mild stimulant and tonic, +and has a quieting effect on the nervous system. + +=Imports and prices.=—Cataria or catnip is imported in but small +quantities. The price paid for the flowering tops and leaves is from 2 +to 8 cents per pound. + + + HOARHOUND. + _Marrubium vulgare_ L. + +=Other common names.=—Houndsbene, marvel, marrube. (Fig. 21.) + +=Range and habitat.=—Hoarhound has been naturalized from Europe, and +has escaped from gardens in this country, being found now rather +abundantly in dry sandy or stony soil in waste places, pastures, +fields, along roadsides, and near dwellings, from Maine to South +Carolina, Texas, and westward to California and Oregon. It is very +abundant in pastures in California, Oregon, and in limited areas in +Indiana, Missouri, Ohio, and Michigan. In southern California this +plant has proved a most troublesome weed, occurring almost everywhere +and growing in such dense masses as to crowd out all other vegetation. +It has spread rapidly over thousands of acres, taking complete +possession of the land and destroying pastures. + +=Description.=—The entire plant has a whitish, woolly appearance, +caused by the dense covering of hairs. It is a perennial plant, and as +will be seen from the characteristic lip-shaped flowers, is a member +of the mint family (Menthaceæ). The whole plant has a rather pleasant, +balsamic odor. + +[Illustration: FIG. 21.—Hoarhound (_Marrubium vulgare_ L.).] + +Hoarhound is a bushy, branching herb, with fibrous roots sending +up numerous woolly stems about 1 to 3 feet high, rounded below and +four-angled above. The leaves are opposite each other, 1 to 2 inches +long, oval or nearly round, wrinkled, somewhat blunt at the apex, +narrowed or somewhat heart shaped at the base, with rounded teeth, +somewhat hairy and wrinkled on the upper surface, and prominently +veined and very hoary on the lower surface. The flowers are whitish, +two-lipped, the upper lip two-lobed, the lower three-lobed, and are +borne in dense, woolly clusters in the axils of the leaves. (Fig. 22.) +The plant flowers from June to September, and the characteristic hooked +calyx teeth of the mature flower clusters cling to the wool of sheep +like a bur, resulting in the scattering of the seeds. + +=Parts used.=—The leaves and tops are used in medicine. These should +be gathered just before the herb is in flower, rejecting the coarse +stalks, and should be dried in the shade in the usual manner. The +balsamic odor diminishes in drying. The herb has a bitter, persistent +taste. + +[Illustration: FIG. 22.—Hoarhound, flowering top.] + +Hoarhound is well known as a remedy for colds, and is also used in +dyspepsia and for expelling worms. + +=Imports and prices.=—A considerable quantity of marrubium or hoarhound +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. + + + + + FARMERS’ BULLETINS. + + +The following is a list of the Farmers’ Bulletins available for +distribution, showing the number, title, and size in pages of each. +Copies will be sent to any address on application to any Senator, +Representative, or Delegate in Congress, or to the Secretary of +Agriculture, Washington, D.
