Arnica montana
The main constituents of Arnica montana are essential oils,
fatty acids, thymol, pseudoguaianolide sesquiterpene lactones
and flavanone glycosides. Pseudoguaianolide sesquiterpenes
constitute 0.2–0.8% of the flower head of Arnica montana. They
are the toxin helenalin and their fatty esters.
2,5-Dimethoxy-p-cymene and thymol methyl ether are the primary
components of essential oils from both the plant's roots and
rhizomes. The quality and chemical constitution of the plant
substance Arnicae flos can be monitored by near-infrared
spectroscopy.
Arnica montana is used as a herbal medicine for analgesic and
anti-inflammatory purposes, but there is insufficient
high-quality clinical evidence for such effects, and it is
toxic when taken internally or applied to injured skin.

Description
Arnica montana is a flowering plant about 18–60 cm (7.1–23.6 in) tall aromatic fragrant, herbaceous perennial. Its basal green ovate leaves with rounded tips are bright coloured and level to the ground. In addition, they are somewhat downy on their upper surface, veined and aggregated in rosettes. By contrast, the upper leaves are opposed, spear-shaped and smaller which is an exception within the Asteraceae. The chromosome number is 2n=38.
The flowering season is between May and August (Central Europe). The hairy flowers are composed of yellow disc florets in the center and orange-yellow ray florets at the external part. The achenes have a one-piece rough pappus which opens in dry conditions. Arnica montana is a hemicryptophyte, which helps the plant to survive the extreme overwintering condition of its habitat. In addition, Arnica forms rhizomes, which grow in a two-year cycle: the rosette part grows at its front while its tail is slowly dying.
