Externally, tinctures and ointments of arnica may be applied freely to the affected area and massaged in. Arnica effectively reduces pain and swelling, and promotes rapid healing. Several commercially prepared ointments are available which are safe to use externally as needed. Arnica ointments should never be applied to broken skin. Homeopathic arnica tablets may be taken separately or along with external applications.
Arnica tablets work quickly, and have no side effects.
A good general-use potency is 30x. Dosages can range from one pill every eight hours to four pills an hour, depending upon need. Suggested dosage rates will be printed on the packaging. Clinical research supports arnica's effectiveness. It is also possible that arnica has preventive benefits.
