Arnica flowers have been used by herbalists for hundreds of years to help promote circulation, and assist with the healing of bruising.
To use these flowers in healing salves, infuse the flowers into a carrier oil and then add the strained oil to your recipe.
Avoid using arnica infused oil or other forms of topical arnica for an extended amount of time, as over time it can cause skin irritation. Should be avoided entirely if pregnant or nursing. External use only.
