Harvest and roughly break apart fresh arnica flowers before packing them firmly into a 1-pint mason jar.

Cover the flowers with olive oil or the neutral oil of your choice.

Fill your double boiler or double boiler DIY setup with 1 inch of water. Pour the arnica and oil into the top of the double boiler or set the mason jar into the DIY boiler setup on a trivet.

Slowly heat the water in the boiler until it reaches 110 to 120°F. Turn off the heat.

For the next 24 to 48 hours, monitor the water temperature, repeating step four to bring it back up to 110 to 120° each time it begins to cool off before turning it off again. Never leave the heat on for a prolonged time or allow the water to get too low.

Once you're satisfied with your infusion, strain the arnica flowers from the oil.

Pour your clean infused oil back into your double boiler or heat-proof container. Bring the water in the boiler back to a simmer.

Add your beeswax to the oil, stirring constantly until it's completely incorporated and smooth.

Pour your salve into small containers.

Allow your salve to cool for at least 30 minutes before using, and label containers with the name and date.
