'''''Apocynum cannabinum''''' ('''dogbane''', '''amy root''', '''hemp dogbane''', '''prairie dogbane''', '''Indian hemp''', '''hemp dogsbane''', '''rheumatism root''', '''dogsbane''', or '''wild cotton''')<ref name="itis" /> is a [[perennial]] [[herbaceous]] plant that grows throughout much of [[North America]]—in the southern half of [[Canada]] and throughout the [[United States]]. It is [[poison]]ous to humans, dogs, cats, and horses. All parts of the plant contain toxic cardiac glycosides that can cause potetintally fatal cardiac arrhythmias if ingested. Some [[Lepidoptera]] can withstand the toxins and feed on this plant, such as the [[hummingbird moth]].

==Description==
''Apocynum cannabinum'' grows up to {{cvt|1|m}} tall. The [[plant stem|stem]]s are reddish and contain a milky [[latex]]. The [[leaves]] are [[opposite leaf|opposite]], [[simple leaf|simple]], broad, and [[lanceolate]], {{cvt|7|–|15|cm|in|frac=4|abbr=on}} long and {{cvt|3|–|5|cm|in|frac=4|abbr=on}} broad, entire, and smooth on top with white hairs on the underside. It [[flower]]s from July to August, has large [[sepal]]s, and a five-lobed white [[corolla (botany)|corolla]]. The flowers are [[Hermaphrodite (botany)|hermaphrodite]], with both male and female organs.<ref name=pfaf/>
[[File:Apocynum cannabinum 20100904b.jpg|thumb|left|''Apocynum cannabinum'' fruits and seeds]]

==Taxonomy==
===Etymology===
''Apocynum'' means "poisonous to dogs".{{Citation needed|date=November 2022}} The [[specific epithet]] ''cannabinum'', and the common names hemp dogbane and Indian hemp refer to its similarity to ''[[Cannabis]]'' as a source of fiber.<ref name="wenner"/> It likely got its name from its resemblance to a European species of the same name.{{which|date=June 2019}}<ref name=heiser/> It is called '''''qéemu''''' {{IPA|sal|qǽːmu|}} in [[Nez Perce language|Nez Perce]]<ref name=qeemu/> and {{IPA|sal|taxʷɨ́s|}} in [[Sahaptin language|Sahaptin]].{{Citation needed|date=November 2022}} The [[Maidu|Maidu Concow people]] call the plant '''''pö''''' ([[Konkow language]]).<ref name=chestnut/>

==Distribution and habitat==
''Apocynum cannabinum'' grows in open [[woodland|wooded]] areas, ditches, and hillsides. It is found in [[gravel]]ly or [[sand]]y soil, mainly near streams in [[shade (shadow)|shady]] or moist places.<ref name=pfaf/> It is native to much of [[North America]]—in the southern half of [[Canada]] and throughout the [[United States]].<ref name=usda/>

==Ecology==

[[File:Apocynum cannabinum 4.jpg|thumb|''Apocynum cannabinum'' flowers]]

The plant serves as a larval host for the snowberry clearwing (''[[Hemaris diffinis]]''),<ref name=hosts/> which is a pollinator that resembles a small hummingbird.<ref name=FS.FED.US/> It is also a host plant for the dogbane tiger moth (''[[Cycnia tenera]]'') and the [[zebra caterpillar]] (''Melanchra picta''). The larvae of ''[[Marmara apocynella]]''<ref name=hosts/> feed on the stems, making a "long whitish serpentine mine".<ref name=gracillariidae/>

==Toxicity==
It is [[poison]]ous to humans,<ref name=pfaf/> dogs, cats, and horses.<ref name=aspca/> All parts of the plant are toxic and contain [[cardiac glycoside]]s.<ref name=pfaf/> The plant is toxic both green and dried.<ref>{{Cite web |date=June 26, 2018 |title=Hemp Dogbane (Apocynum cannabinum) : USDA ARS |url=https://www.ars.usda.gov/pacific-west-area/logan-ut/poisonous-plant-research/docs/hemp-dogbane-apocynum-cannabinum/ |url-status=live |archive-url=https://archive.today/20240711015946/https://www.ars.usda.gov/pacific-west-area/logan-ut/poisonous-plant-research/docs/hemp-dogbane-apocynum-cannabinum/ |archive-date=July 11, 2024 |access-date=2024-07-11 |website=www.ars.usda.gov}}</ref> The stems contain a white sap capable of causing skin [[blister]]s.<ref name=ncsu/>

==Uses==
===Fiber===
Much like flax and hemp, ''Apocynum cannabinum'' contains long fibers in the stems, known as bast fibers, which can be extracted and used to create textiles. The fibers are very fine and strong, with a silky texture, and easier to process than hemp.<ref name="wenner"/> The stalks of this plant have been used as a source of fiber by [[Native Americans in the United States|Native Americans]]<ref name=coville/> to make [[Bow and arrow|bows]], [[Bow drill|fire-bows]], [[Net (device)|nets]], [[tie down straps|tie-down straps]], hunting nets, fishing lines, bags,<ref name=kalm/> and clothing.<ref name=heiser/> According to Craig Bates of the Yosemite Museum, five stalks of the plant are needed to make one foot of cordage. A large bag used for storing roots would take one to three months to complete.<ref>{{cite web |title=Indian hemp |url=https://plants.usda.gov/DocumentLibrary/plantguide/pdf/pg_apca.pdf |website=plants.usda.gov |publisher=United States Department of Agriculture}}</ref> The stems should be harvested in the fall, after the leaves have fallen and the stalks have turned a deep reddish-brown color. Since cutting the stalks promotes regrowth in the spring, as much as possible should be harvested. Unused stems are traditionally cleared away by burning, which causes the plant to grow back taller and straighter in spring.

===Food===
The [[seeds]] have an edible use as a meal (raw or cooked) when ground into a powder.<ref name=pfaf/>

===Chewing gum===
The plant's latex sap can be squeezed from the plant and allowed to stand overnight to harden into a white [[natural gum|gum]] which can be used (sometimes mixed with clean [[clay]]) as [[chewing gum]].<ref name=pfaf/>

===Phytoremediation===
''Apocynum cannabinum'' can be used to sequester [[lead]] in its [[Biomass (ecology)|biomass]] by taking it up from the soil through its roots. This process, called [[phytoremediation]], could help clean sites contaminated with lead.<ref name=lasat/>

===Medicinal===
[[File:Apocynum cannabinum 7.jpg|thumb|upright=1.5|''Apocynum cannabinum'' showing sap from a broken leaf]]
It is used in [[herbal medicine]] to treat [[fever]] and to slow the pulse.<ref name=felter/> ''Apocynum cannabinum'' has been employed by various Native American tribes to treat a wide variety of complaints including [[rheumatism]], [[cough]]s, [[poxvirus|pox]], [[whooping cough]], [[asthma]], [[Human parasite|internal parasites]], [[diarrhea]], and to increase [[lactation]].<ref name=pfaf/> The root has been used as a tonic, [[cardiotonic]], [[diaphoretic]], [[diuretic]], an [[emetic]] (to induce [[vomiting]]), and an [[expectorant]].<ref name=felter/><ref name=pfaf/> It is harvested in the [[autumn]] and dried for later use. The fresh root is medicinally the most active part. A weak [[herbal tea|tea]] made from the dried root has been used for [[cardiac disease]]s and as a [[vermifuge]] (an agent that expels [[parasitic worms]]). The milky sap is a [[folk remedy]] for [[genital warts]].<ref name=pfaf/>
