Arnica is a flower found in mountainous regions of both Europe and North America.
It's considered to be one of the best for treating injuries like broken bones, strains, sprains, and bruising.
It can prevent excessive fluid from leaking into the interstitial spaces, leading to bruising, swelling, and pain.
Most accounts don't recommend arnica internally, and some case reports have suggested liver toxicity as a result.
As such, arnica should not be used on broken skin, which offers a direct route to the bloodstream, and eventually the liver.
Topical creams, salves, and liniments are common, and easy methods of applying arnica and are a great thing to have around in a first aid kit.
