Arnica chamissonis
provided by wikipedia EN
Arnica chamissonis, the Chamisso arnica,[2] is a North American species of plants in the family Asteraceae. It is very similar to Arnica montana. Arnica chamissonis is native to North America and naturalized in parts of Europe while A. montana is indigenous to Europe.[3][4]
Distribution and habitat
Arnica chamissonis is native to western North America, including Alaska, and most of Canada including Yukon and Northwest Territories.[5][6] Arnica chamissonis is perennial. It has a temperature minimum of −33 °F (−36 °C).[5] They are adapted to both coarse and medium textured soils with a pH between 6.0–7.2.[5] Since this plant uses a lot of moisture, it has a precipitation requirement of between 14–24 inches (36–61 cm).[5] It generally prefers moist meadows and conifer forests and often grows in montane to subalpine zones, 0–3,500 metres (0–11,483 ft).[7] Seeds are easily available and the plant can be grown in a home garden. It prefers full sun exposure and an average soil temperature of 65–75 °F (18–24 °C).[8]
Morphology
Arnica chamissonis has yellow flowers with green medium textured foliage.[5] The leaves of the Arnica chamissonis are grouped in 4–10 pairs.[7] It produces brown seeds and has an active growth period of the spring and summer. It has rhizomatous growth and grows at a moderate rate.[5] Rhizomatous plants have an underground stem with small fiber-like adventitious roots. A. chamissonis has a mature height of roughly 2.5 feet (76 cm).
Reproduction and growth
Arnica chamissonis has an active bloom period throughout the summer.[5] There are approximately 400,000 seeds per pound. These individuals have a medium seedling vigor and a moderate vegetative spread rate.[5] Seedling vigor refers to "the expected seedling survival percentage of the plant compared to other species with the same growth habit." A vegetative spread rate refers to how quickly a plant can spread through a given area. In general, A. chamissonis can be grown in a container, by using seeds or sprigs.[5]
Both A. montana and A. chamissonis contain the toxin helenalin.
The species is named for German poet and botanist Adelbert von Chamisso, 1781–1838.[9][10]

Arnica chamissonis, l'arnica dite américaine, est une plante herbacée vivace rhizomateuse du genre Arnica et de la famille des Asteraceae. Elle est originaire d'Amérique du Nord.
Une sous-espèce, Arnica chamissonis subsp. foliosa est considérée par les pharmacopées allemande (DA89) et européenne comme thérapeutiquement équivalente à Arnica montana. Elle a en effet une composition chimique proche, bien que distincte. Elle est beaucoup plus aisée à cultiver et, fleurissant dès l'année de mise en place, beaucoup plus productive. En cas d'allignement des pharmacopée française et autres pharmacopéés nationales sur la pharmacopée européenne, il est probable que les cultures de Arnica chamissonis subsp. foliosa remplaceront la production issue de stations sauvages de Arnica montana[1],[2].

Arnica chamissonis é uma espécie de planta com flor pertencente à família Asteraceae. É nativa dos prados úmidos do oeste da América do Norte.
Geralmente prefere prados úmidos e florestas de coníferas e freqüentemente cresce em altitude e subalpina, até uma altitude de 3.500 metros. As sementes estão prontamente disponíveis e a planta pode ser cultivada em um jardim doméstico.
As folhas são agrupadas em 4 a 10 pares.[2] Possui flores amarelas com folhagem verde de textura média.[1] Produz sementes marrons e tem um período de crescimento ativo da primavera ao verão. Tem um crescimento rizomatoso.
Contém helenalina, uma lactona que é tóxica se ingerida, mas um ingrediente essencial em preparados anti-inflamatórios, de uso externo exclusivamente, como pomadas.[3]
