Biofield therapies: energy medicine and primary care.

Energy medicine modalities, also known as biofield therapies, are perhaps the most mysterious and controversial complementary alternative medicine therapies. Although many of these approaches have existed for millennia, scientific investigation of these techniques is in its early stages; much remains to be learned about mechanisms of action and efficacy. These techniques are increasingly used in clinical and hospital settings and can be incorporated into an integrative primary care practice. This article describes several energy medicine and biofield therapies and outlines key elements they hold in common. Several specific approaches are described. Research findings related to the efficacy of energy medicine are summarized, and proposed mechanisms of action and safety issues are discussed. Guidelines are offered for primary care providers wishing to advise patients about energy medicine or to integrate it into their practices, and Internet and other resources for obtaining additional information are provided.
