Book excerpt: The first of its kind, this guidebook provides an overview of clinical holistic interventions for mental-health practitioners. Submissions from 21 contributors examine the validity of different methods and provide information on credentialed training and licensure requirements necessary for legal and ethical practice. Chapters covering a range of healing modalities describe the populations and disorders for which the intervention is most effective, as well as the risks involved, and present research on the effectiveness of treatment, with step-by-step sample clinical sessions.
