Arnica is a homeopathic remedy established by Dr. Samuel Hahnemann to support healing and reduce bleeding. It is primarily used for pain, injury, and shock. Arnica can be used internally or externally to treat low back pain, muscle pains, bruises, sprains, arthritis, fever, and injuries. The flowering herb and root are used to prepare the homeopathic remedy of Arnica through a process of infusion, straining, dilution, and succession that removes any toxic substances, making it safe for use.
