Arnica is a bright orange-yellow and daisy-like flowers that once covered the European meadows which were used for perennial herb. It was also called " Mountain tobacco" in Switzerland because it spanned the entire mountain ranges, but those days are long gone. 
There are many species of Arnica ( Montana). However, they all share a few compounds thought to reduce anti-inflammatory, pain and wound / incisions irritation, post operatively.  
Arnica Montana can be used in conjunction with conventional medicines to reduce swelling, ease inflammation, and reduce pain and diminish wound irritation following cosmetic surgery procedures. 
It is safe to use when it is applied inside your body taken orally. 
Never apply Arnica in any form on broken skin or an open wound which can be toxic if it gets into your body via an open wound. The compound Helenalin found in Arnica can cause mild rash.
