Arnica is a flower that is medicinally prepared for the treatment of bruises, muscle or joint pains. Sanar Naturals Arnica Roll On combines the effectiveness of the flower with menthol to create a more potent, natural topical analgesic. It is often used for back or neck pain and is great for athletes with muscle soreness to temporarily relieve muscle pain and stiffness, swelling from injuries and discoloration from bruising. Arnica is trusted by professional athletes to soothe sore muscles, by prominent cosmetic surgeons to relieve post-procedure pain, and by savvy moms to treat playground bumps and bruises. Claims based on traditional homeopathic practice, not accepted medical evidence.
