In the Complementary/ Alternative Therapy (CAM) community, it is commonly accepted that there is a biological energy (bioenergy) that surrounds and interpenetrates the body. The National Center for Complimentary and Alternative Medicine (NCCAM) acknowledges energy medicine as one of the branches of complementary and alternative medicine. Conventional science has been skeptical about this because it has been difficult to develop instruments that objectively measure bioenergies. This discussion explores theories to confirm the existence of bioenergies and to begin to explain them.
