Arnica (Arnica montana)

Arnica Overview:

Arnica is a flower found in mountainous regions of both Europe and North America. The flowers are used on injuries like broken bones, strains, sprains, and bruising. It is considered to be one of the best for this as it can prevent excessive fluid from leaking into the interstitial spaces, leading to bruising, pswelling, and pain.

Most accounts do not recommend arnica internallywith some case reports suggesting liver toxicity. 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.
