Description:
The genus Apocynum contains only four species, two of which Apocynum androsaemifolium and A. cannabinum, or Black Indian Hemp, resemble each other very closely, the roots being distinguished by the thick-walled stone cells, which in the former are found in an interrupted circle near the middle of the bark, and in the latter are absent.
A. a. ndrosaemifolium is a perennial herb, 5 or 6 feet in height, branching, and, in common with the other three members of the genus, yielding on incision a milky juice resembling indiarubber when dry.
The leaves are dark green above, paler and downy beneath, ovate, and from 2 to 3 inches long. The flowers are white, tinged with red, having five scales in the throat of the corolla which secrete a sweet liquid, attractive to flies. These scales are very sensitive, and when touched bend inward, imprisoning the insects…..…click & see the pictures
The milky root is found in commerce in cylindrical, branched pieces, about a quarter of an inch thick, reddish or greyish brown outside, longitudinally wrinkled, and having a short fracture and small pith. There is scarcely any odour, and the taste is starchy, afterwards bitter and acrid.

Parts Used for medicine: The dried rhizome, roots.
Constituents: The nature of the active principle is uncertain. A glucoside, Apocynamarin, was separated, but the activity is thought to be due not to the glucoside, but to an intensely bitter principle, Cymarin.
Medicinal Uses:
Apocynum androsaemifolium is an unpleasantly bitter stimulant irritant herb that acts on the heart, respiratory and urinary systems, and also on the uterus. It was widely employed by the native North American Indians who used it to treat a wide variety of complaints including headaches, convulsions, earache, heart palpitations, colds, insanity and dizziness. It should be used with great caution, and only under the supervision of a qualified practitioner if taking this plant internally. The root contains cymarin, a cardioactive glycoside that is toxic to ruminants. The root is cardiotonic, cathartic, diaphoretic, diuretic, emetic and expectorant. It has a powerful action in slowing the pulse and also has a very strong action on the vaso-motor system, it is rather an irritant to the mucous membranes though, so some people cannot tolerate it. The juice of the fresh root has been used in the treatment of syphilis. The sap of the plant has been applied externally to get rid of warts. The roots were boiled in water and the water drunk once a week in order to prevent conception. The green fruits were boiled and the decoction used in the treatment of heart and kidney problems and for the treatment of dropsy. This preparation can irritate the intestines and cause unpleasant side-effects. It is used as an alterative in rheumatism, syphilis and scrofula.
Other Uses:The bark yields a good quality fibre that is used for making twine, bags, linen etc. It is inferior to A. cannabinum. The fibre is finer and stronger than cotton. It can be harvested after the leaves fall in the autumn but is probably at its best as the seed pods are forming. The plant yields a latex, which is a possible source of rubber. It is obtained by making incisions on the stem and resembles indiarubber when dry.
Known Hazards: The plant is poisonous, due to the cardiac glycosides it contains.
