Etymology
Apocynum androsaemifolium Linnaeus. From the Greek 'apo': far from and 'kyôn': dog, because of its toxic effects on dogs; Androsema-leaved androsaemifolium (Hypericum androsaemum).
Distribution and habitat
The plant is widespread across most of Canada, the United States (including Alaska but excluding Florida), and northeast Mexico.[4][5][6] Its native habitats include forests, woodlands, forest edges, prairies, meadows, and fields.[7] It prefers dry soils at low to medium elevations.[4]
Ecology
Animals naturally avoid the plant.[4]
Toxicity
The plant is poisonous[8] due to the cardiac glycosides and resins it contains.[9] Escalating doses usually cause vomiting and diarrhea. Other symptoms include dizziness, colour hallucinations, cold sweats, and excessive urination. In extreme cases, the heart rate may slow before fatal convulsions. Young milkweed shoots must be distinguished from those of the androsemus leaf beetle because they appear at the same time.Шаблон:Citation needed
Uses
Native Americans used spreading dogbane in numerous ways. The plant was used as a medicine to treat ailments including headaches, convulsions, ear ache, heart palpitations, colds, insanity, dizziness, rheumatism, scrofula, and syphilis. The plant can also be used as a contraceptive.[10] Among the Ojibwe, the root was used as a gynecological, oral, and throat aid, as well as an analgesic for headaches and a diuretic during pregnancy. The Ojibwe also consumed the root of the plant during the medicine lodge ceremony.[11] The Forest Potawatomi made medicinal use of the roots as well, and the Prairie Potawatomi used the plant's fruits to treat heart and kidney problems.[10] The stem fibers of the plant are very strong,[11] and Native Americans used them as a thread for sewing.[12] Outside of the Americas, spreading dogbane was also used to treat heart disease in Europe during the first half of the 20th century.[13]
