What is the role of Endorphins in Auriculotherapy?
The endorphins, endogenous morphine molecules that relieve pain in a manner similar to external opiate chemicals, have been used as one explanation for how auriculotherapy serves to relieve pain. Both animal research and human studies have shown that stimulation of ear acupuncture points appears to cause the systemic release of endorphins. Administration of the opiate antagonist naloxone partially blocks the analgesia produced by either auriculotherapy or by acupuncture.
