If you have muscle soreness, you need Arnica Montana! I first learned of Boiron products last year, and have my own little medicine cabinet of the blue and purple BOIRON tubes! These are tiny little white pellets that you take usually 5-6 at a time, and each tube treats a different ailment you may have. Many health food stores carry the BOIRON line, and each tube has different dosage recommendations and costs may vary. I prefer using these homeopathic products.
