'''''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.
==Uses==
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.
