Arnica, or arnica montana, is a pretty daisy-like flower.
This plant is very useful in treating bruised, strained or sprained parts of the body. It has also been used in helping wounds heal.
However, the plant itself is poisionous if ingested in large amounts. Ironically, unprepared arnica plants can cause skin irritation.
It is used as a gel or as a tincture.
