title: Use of Arnica to relieve pain after carpal-tunnel release surgery.
abstract: BACKGROUND
  Arnica is commonly used by the public as a treatment for bruising and swelling.
  
  
  OBJECTIVE
  To assess whether Arnica administration affects recovery from hand surgery.
  
  
  METHODS
  Double-blind, randomized comparison of Arnica administration versus placebo.
  
  
  METHODS
  Specialist hand surgery unit at the Queen Victoria NHS Trust.
  
  
  METHODS
  Thirty-seven patients undergoing bilateral endoscopic carpal-tunnel release between June 1998 and January 2000.
  
  
  METHODS
  Homeopathic Arnica tablets and herbal Arnica ointment compared to placebos.
  
  
  METHODS
  Grip strength, wrist circumference, and perceived pain measured 1 and 2 weeks after surgery.
  
  
  RESULTS
  No difference in grip strength or wrist circumference was found between the 2 groups. However, there was a significant reduction in pain experienced after 2 weeks in the Arnica-treated group (P<.03).
  
  
  CONCLUSIONS
  The role of homeopathic and herbal agents for recovery after surgery merits further investigation.
