Book excerpt: For most clinicians, the science and evidence for many integrative therapies is largely unknown or considered suspect. Most physicians don't have time to learn integrative approaches and aren't sure what to recommend or which approaches have merit or improved outcomes. In Integrative Preventive Medicine, clinicians have easy access to the best practices in integrative medicine and expectations for outcomes. The current state of the science is also presented. Authors are leaders in their fields, with decades of expertise and leadership in their fields.
