Arnica Oil

What is arnica oil derived from? What is the benefits of using it?
How to make an oil infusion, and how to use it.

The oil is made from the arnica plant found in the central and northern regions of the Northern Hemisphere. It is native in the mountains of Europe and Siberia and cultivated in North America.

The plant grows 1-2 feet and has daisy like yellow-orange flowers and bright green toothed slightly hairy and round tipped leaves.

The fresh or dried flower heads are what is used for medicinal preparations and are used to make an infused oil that can be used as a carrier.

The essential oil is highly toxic and should not be used in aromatherapy. Be sure and store it separate from your essential oils.

Other extractions do have valuable uses. It is most common found as a tincture, but you can also get an infused oil, or a hydrolate which is safe to use.

As a carrier oil Arnica montana should not be used pure, if you have a pure oil always dilute in a 30/70 solution (use at least 70% or more of a 100% use carrier oil like almond or grapeseed).

It is usually sold as ‘arnica massage base oil” which is pre-diluted, as it is very expensive, so no further diluting would be necessary, but make sure what you have before use.

Making an Infused Oil

You can make an infused oil with one part dried arnica flowers and five parts vegetable oil.
Put the dried flowers in a glass jar and cover with carrier oil. Put a paper towel over the top of the jar and secure with a rubber band or the canning ring if using a canning jar. Let set for about six weeks, checking regularly to make sure the dried flowers stay under the oil, add more if needed.
When done strain your oil with cheesecloth and a strainer. Put in your jar, cap and label it.

Mountain Rose Herbs has dried bulk arnica flowers.

They also have carrier oils for your infusions.
