'''''Apocynum cannabinum''''' ('''Dogbane''', '''Amy Root''', or '''Indian hemp''') is a [[perennial plant|perennial]] [[herbaceous]] plant that grows throughout much of [[North America]], in the southern half of [[Canada]] and throughout the [[United States]]. It grows up to 2 meters tall. It prefers moist places. It is a [[poison]]ous plant; the name means "poisonous to dogs". All parts of the plant are poisonous and can cause cardiac arrest if ingested.
 +
 +
The stems are reddish and contain a milky [[latex]] capable of causing skin blisters. The [[leaf|leaves]] are opposite, simple broad lanceolate, 7-15 cm long and 3-5 cm broad, entire, and smooth on top with white hairs on the underside. The [[flower]]s are produced in mid summer, with large sepals, and a five-lobed white corolla.
 +
 +
It grows in open wooded areas, ditches, and hillsides; in [[garden]]s it can be invasive, growing from spreading roots.

Apocynum cannabinum, Linn. Branches erect or nearly so: lobes of corolla nearly erect, the tube not longer than calyx: Lvs. ovate to lance-oblong, short-petioled: cymes dense; fls. greenish white. Northern states; common.— Not known to be in the trade, but likely to be confounded with the above. Root emetic, cathartic, diaphoretic, expectorant, and diuretic. The tough fibrous bark of the stalks formerly used by the Indians for making twine.

Indian hemp was used as a source of fiber by [[North American Indians|Native Americans]], to make hunting nets, fishing lines, clothing, and twine. It was also used in [[herbal medicine]] to treat syphilis, rheumatism, intestinal worms, fever, asthma, and dysentery. Although the toxins from the plant can cause nausea and catharsis, it has also been used for slowing the pulse.
