I have used Arnica Cordifolia for sore, strained and bruised muscles. Externally rubbed extracted oils from the flower on the injured site and found bruising, soreness, and muscle strains to be repaired much more quickly than I had anticipated. I believe the richness of the soils, and amount of direct solar hours on the plant increases the fragrance and medicinal chemicals which in turn increases efficacy. I love to partake in a scientific study/experiment of the healing properties of the Heart Leaf Arnica which grows on our south facing rich soil sites.
