Acokanthera
''Acokanthera'' is a genus of flowering plants in the family Apocynaceae. It comprises 5 species and is generally restricted to Africa, although '' Acokanthera schimperi'' also occurs in Yemen. Its sap contains the deadly cardiotoxic glycoside '' ouabain''. The sap is among the most commonly used in arrow poisons, including those used for poaching elephant.

Acokanthera Schimperi
''Acokanthera schimperi'', arrow poison tree, belonging to the family Apocynaceae, is a small tree native to eastern and central Africa as well as to Yemen. Uses The bark, wood and roots of ''Acokanthera schimperi'' are used as an important ingredient of arrow poison in Africa. All plant parts contain acovenoside A and ouabaïne, which are cardiotonic glycosides. Its fruit is edible, and is eaten as a famine food. When ripe they are sweet but also slightly bitter. Unripe fruits have caused accidental poisoning as they are highly toxic. The maned rat spreads the plant's poison on its fur and becomes poisonous. It is also used in traditional African medicine. In Ethiopia, for example, ''Acokanthera schimperi'' leaves have been traditionally used for jaundice. Geographic distribution ''Acokanthera schimperi'' is native to Eritrea, Ethiopia, Somalia, Somaliland, Kenya, Uganda, Tanzania, Rwanda and DR Congo.

Acokanthera Oblongifolia
''Acokanthera oblongifolia'' (commonly known as African wintersweet, dune poison bush, Hottentot's poison, poison arrow plant or wintersweet) is a plant in the family Apocynaceae. It grows as an evergreen shrub or small tree up to tall. Its fragrant flowers feature a white tinged pink corolla. The berries are purple when ripe. Its habitat is dry forest and coastal thickets. ''Acokanthera oblongifolia'' is used in local African medicinal treatments for snakebites, itches and internal worms. The plant has been used as arrow poison. The species is native to Mozambique and South Africa. Taxonomy It was first described in 1844 by Christian Ferdinand Friedrich Hochstetter as ''Carissa oblongifolia,'' reassigned in 1876 to the genus, '' Acokanthera'', by George Bentham and Joseph Hooker, but not validly, and finally, in 1895, validly published by Benjamin Daydon Jackson Benjamin Daydon Jackson (3 April 1846 – 12 October 1927) was a pioneering botanist and taxonomer who wrote t ...

Apocynaceae Genera
Apocynaceae (from ''Apocynum'', Greek for "dog-away") is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, because some taxa were used as dog poison Members of the family are native to the European, Asian, African, Australian, and American tropics or subtropics, with some temperate members. The former family Asclepiadaceae (now known as Asclepiadoideae) is considered a subfamily of Apocynaceae and contains 348 genera. A list of Apocynaceae genera may be found here. Many species are tall trees found in tropical forests, but some grow in tropical dry (xeric) environments. Also perennial herbs from temperate zones occur. Many of these plants have milky latex, and many species are poisonous if ingested, the family being rich in genera containing alkaloids and cardiac glycosides, those containing the latter often finding use as arrow poisons. Some genera of Apocynaceae, such as '' Adenium'', bleed clear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ouabain
Ouabain or (from Somali ''waabaayo'', "arrow poison" through French ''ouabaïo'') also known as g-strophanthin, is a plant derived toxic substance that was traditionally used as an arrow poison in eastern Africa for both hunting and warfare. Ouabain is a cardiac glycoside and in lower doses, can be used medically to treat hypotension and some arrhythmias. It acts by inhibiting the Na/K-ATPase, also known as the sodium-potassium ion pump. However, adaptations to the alpha-subunit of the Na+/K+-ATPase via amino acid substitutions, have been observed in certain species, namely some herbivore- insect species, that have resulted in toxin resistance. It is classified as an extremely hazardous substance in the United States as defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act (42 U.S.C. 11002), and is subject to strict reporting requirements by facilities which produce, store, or use it in significant quantities. Sources Ouabain can be found in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
