CHAPTER XXI.

COHOSH--BLACK AND BLUE.

Black Cohosh.

Cimicifuga Racemosa (L.) Nutt.

Synonym--Actaea Racemosa L.

Pharmacopoeial Name--Cimicifuga.

Other Common Names--Black snakeroot, bugbane, bugwort,

rattlesnakeroot, rattleroot, rattleweed, rattletop, richweed,

squawroot.

Habitat and Range--Altho preferring the shade of rich woods, black

cohosh will grow occasionally in sunny situations in fence corners

and woodland pastures. It is most abundant in the Ohio Valley, but it

occurs from Maine to Wisconsin, south along the Allegheny Mountains

to Georgia and westward to Missouri.

Description of Plant--Rising to a height of 3 to 8 feet, the showy,

delicate-flowered spikes of the Black Cohosh tower above most of the

other woodland flowers, making it a conspicuous plant in the woods

and one that can be easily recognized.

Spikes and Rootstock.]

Black Cohosh is an indigenous perennial plant belonging to the

same family as the Golden Seal, namely, the crowfoot family

(Ranunculaceae). The tall stem, sometimes 8 feet in height, is rather

slender and leafy, the leaves consisting of three leaflets, which are

again divided into threes. The leaflets are about 2 inches long,

ovate, sharp pointed at the apex, thin and smooth, variously lobed

and the margins sharply toothed. The graceful, spikelike terminal

cluster of flowers, which is produced from June to August, is from 6

inches to 2 feet in length. Attractive as these flower clusters are

to the eye, they generally do not prove attractive very long to those

who may gather them for their beauty, since the flowers emit an

offensive odor, which account for some of the common names applied to

this plant, namely, bugbane and bugwort, it having been thought that

this odor was efficacious in driving away bugs. The flowers do not

all open at one time and thus there may be seen buds, blossoms, and

seed pods on one spike. The buds are white and globular and as they

expand in flower there is practically nothing to the flower but very

numerous white stamens and the pistil, but the stamens spread out

around the pistil in such a manner as to give to the spike a somewhat

feathery or fluffy appearance which is very attractive. The seed pods

are dry, thick and leathery, ribbed, and about one-fourth of an inch

long, with a small beak at the end. The smooth brown seeds are

enclosed within the pods in two rows. Any one going thru the woods in

winter may find the seed pods, full of seeds, still clinging to the

dry, dead stalk, and the rattling of the seeds in the pods as the

wind passes over them has given rise to the common names

rattle-snakeroot (not "rattlesnake"-root), rattleweed, rattletop and

rattleroot.

Description of Rootstock--The rootstock is large, horizontal and

knotty or rough and irregular in appearance. The upper surface of the

rootstock is covered with numerous round scars and stumps, the

remains of former leaf stems, and on the fresh rootstocks may be seen

the young, pinkish white buds which are to furnish the next season's

growth. From the lower part of the rootstock long, fleshy roots arc

produced. The fresh rootstock is very dark reddish brown on the

outside, white within, showing a large central pith from which

radiate rays of a woody texture, and on breaking the larger roots

also the woody rays will be seen in the form of a cross. On drying,

the rootstock becomes hard and turns much darker, both internally and

externally, but the peculiar cross formation of the woody rays in

both rootstock and roots, being lighter in color, is plainly seen

without the aid of a magnifying glass. The roots in drying become

wiry and brittle and break off very readily. Black cohosh has a heavy

odor and a bitter, acrid taste.

Collection, Prices and Uses--The root should be collected after the

fruit has ripened, usually in September. The price ranges from 2 to 3

cents a pound.

The Indians had long regarded black cohosh as a valuable medicinal

plant, not only for the treatment of snake bites, but it was also a

very popular remedy among their women, and it is today considered of

value as an alterative, emmenagogue, and sedative, and is recognized

as official in the United States Pharmacopoeia.

Blue Cohosh.

Caulophyllum Thalictroides (L.) Michx.

Other Common Names--Caulophyllum, pappoose-root, squawroot,

blueberryroot, blue ginseng, yellow ginseng.

[Illustration: Blue Cohosh (Caulophyllum Thalictroides).]

Habitat and Range--Blue Cohosh is found in the deep rich loam of

shady woods from New Brunswick to South Carolina, westward to

Nebraska, being abundant especially thruout the Allegheny Mountain

region.

Description of Plant--This member of the barberry family

(Berberidaceae) is a perennial herb, 1 to 3 feet in height, and

indigenous to this country. It bears at the top one large, almost

stemless leaf, which is triternately compound--that is, the main leaf

stem divides into three stems, which again divide into threes, and

each division bears three leaflets. Sometimes there is a smaller

leaf, but similar to the other, at the base of the flowering branch.

The leaflets are thin in texture, oval, oblong, or obovate and 3 to 5

lobed.

In the early stage of its growth this plant is covered with a sort of

bluish green bloom, but it generally loses this and becomes smooth.

The flowers are borne in a small terminal panicle or head, and are

small and greenish yellow. They appear from April to May, while the

leaf is still small. The globular seeds, which ripen about August,

are borne on stout stalks in membranous capsules and resemble

dark-blue berries.

Description of Rootstock--The thick, crooked rootstock of Blue Cohosh

is almost concealed by the mass of matted roots which surrounds it.

There are numerous cup-shaped scars and small branches on the upper

surface of the rootstock, while the lower surface gives off numerous

long, crooked, matted roots. Some of the scars are depressed below

the surface of the rootstock, while others are raised above it. The

outside is brownish and the inside tough and woody. Blue Cohosh

possesses a slight odor and a sweetish, somewhat bitter and acrid

taste. In the powdered state it causes sneezing.

Collection, Prices and Uses--The root is dug in the fall. Very often

the roots of Golden Seal or twinleaf are found mixed with those of

Blue Cohosh. The price of Blue Cohosh root ranges from 2 1/2 to 4

cents a pound.

Blue Cohosh, official in the United States Pharmacopoeia for 1890, is

used as a demulcent, antispasmodic, emmenagogue and diuretic.
