To heal a wound, turn up the voltage is a rather interesting report of scientists using electric signals to heal wounds. They seem to be proud they've identified this isn't homeopathy. But, really, this is rather similar to energy healing in its many form including homeopathy.
Consider the discussion in Energy Medicine: The Scientific Basis. Dr. Oschman in that book identifies Energy Healing as a manifestation of electrical currents in the body, and that some people have learned to direct energy currents out their hands or in other ways.
