Arnica /ˈɑːrnᵻkə/ is a genus of perennial, herbaceous plants in the sunflower family (Asteraceae). The genus name Arnica may be derived from the Greek , "lamb", in reference to the plants' soft, hairy leaves. Arnica is also known by the names Mountain Tobacco and, confusingly, Leopard's bane and Wolfsbane—two names that it shares with the entirely unrelated genus Aconitum.
This Circumboreal and montane (subalpine) genus occurs mostly in the temperate regions of western North America, with a few species native to the Arctic regions of northern Eurasia and North America.
Several species, such as Arnica montana and A.chamissonis, contain helenalin, a sesquiterpene lactone that is a major ingredient in anti-inflammatory preparations (used mostly for bruises).
Arnica species are used as food plants by the larvae of some Lepidoptera species including Bucculatrix arnicella.
Arnica was previously classified in the tribe Senecioneae because it has a flower or pappus of fine bristles.
Arnica plants have a deep-rooted, erect stem that is usually unbranched. Their downy opposite leaves are borne towards the apex of the stem. The ovoid, leathery basal leaves are arranged in a rosette.
