Arnica has long been a remedy for sore, aching muscles, joint pain, arthritis, rheumatism and body aches. Arnica also improves discoloration of bruises, which is valuable because a bruise is a blood clot. This remedy is valuable after surgery, from athletic injury, and for kids injured on the playground. In today’s world of constant advertising, old, trusted products sometimes get forgotten or overlooked. This is one of them. It works, safely and without side effects.
