Book excerpt: EFT (Emotional Freedom Techniques or "tapping") is used by an estimated 10 million people worldwide. Yet a lack of standardization has led to a field in which dozens of forms of EFT, with varying degrees of fidelity to the original, can be found. This led to the establishment of Clinical EFT, the form of EFT taught in the original EFT Manual and associated materials, and validated in over 20 clinical trials. In this volume, the most noted scholars, researchers and clinicians in the field compile a definitive outline of the EFT protocol, as it is applied in medicine, psychiatry, psychotherapy, and life coaching. This first volume covers • Biomedical and Physics Principles • Psychological Trauma • Fundamental Techniques of Clinical EFT. This series of handbooks is essential reading for anyone wishing to understand EFT as validated in research, science, and best clinical practice.
