Overview

Arnica is an aromatic perennial, usually about 1 ft (30 cm) high, with downy, oval-shaped leaves and bright yellow daisy-like flowers. Well-known for reducing swelling, bruising, and pain from injuries, it is frequently used as a homeopathic remedy (both internally and topically) for bruises, sprains, and sore muscles. Higher-dose tinctures have a stronger anti-inflammatory action and may serve as a cardiac tonic by improving blood flow to the coronary vessels, but such usage must be closely supervised.
