Energy medicine

The National Center for Complementary and Alternative Medicine defines Energy Medicine as therapies that use forces that are, and are not, detectable with conventional scientific instrumentation. There are two broad subclasses:
 * Bioelectromagnetic-based therapies involve the unconventional use of electromagnetic fields, such as pulsed fields, magnetic fields, or alternating-current or direct-current fields.
 * Biofield therapies are intended to affect energy fields that purportedly surround and penetrate the human body.
