Arnica

Arnica (Arnica montana L.) is a perennial medicinal herb that belongs to the Asteraceae family. It has erect robust stems that grow to be 20 to 60 cm high with large yellowish orangish flowers with "unkempt" looking petals and a pleasant aromatic scent. In France it’s very common and the French call it “Tabac des Vosges”, because some people who live in the mountains use it as snuff. 
It’s traditionally used as an exceptional herbal remedy for trauma, edema, and for bangs and bruises, because it stimulates circulation, allows for the reabsorption of hematoma and gets rid of waste more quickly.
