Book excerpt: Part of the Weil Integrative Medicine Library, this volume provides a rational and evidence-based approach to the integrative therapy of mental disorders integrating the principles of alternative and complementary therapies into the principles and practice of conventional psychiatry and psychology. Integrative Psychiatry and Brain Health examines what works and what doesn't, and offers practical guidelines for physicians to incorporate integrative medicine into their practice and to advise patients on reasonable and effective therapies.
