Arnicare Arthritis Cream by Boiron combines two pain relievers in one formula for dual action pain relief where you need it most. It’s scientifically formulated with Arnica and Harpagophytum (devil’s claw), which work together to reduce minor stiffness, soreness, and joint pain of arthritis.* This topical is ideal for sudden flare-ups as it quickly absorbs into skin to take away pain at its source.
