Botanical Profile
Arnica is a traditional European mountain and medicinal plant of the Asteraceae family. Pharmacognostic literature focuses primarily on the flower heads, which are described as Arnicae flos.
Arnica montana L. is distributed mainly in the middle and high mountain regions of Europe and grows preferentially in nutrient-poor meadows and on acidic soils. Its yellow flower heads and mountain habitat characterise the botanical classification of the plant.
Phytochemistry
Phytochemically, arnica is associated in particular with sesquiterpene lactones, including helenalin and dihydrohelenalin derivatives. Flavonoids, phenolic acids, essential-oil constituents and triterpenes are also described.
Traditional Uses
The EMA monograph Community herbal monograph on Arnica montana L., flos (EMA/HMPC/198793/2012) describes traditional external herbal-use contexts, particularly in connection with blunt trauma, bruising and muscle-related contexts. ESCOP likewise lists Arnicae flos as a traditional European medicinal plant with a focus on external applications.
Current Research
Modern research investigates in particular sesquiterpene lactones, helenalin derivatives, inflammation-related signalling pathways and experimental cell models. Lyss et al. described experimental relationships between helenalin and NF-κB-related signalling pathways. These fields of research require scientific contextualisation and do not constitute therapeutic statements about products.
