This is a segment of a video produced by Gary Craig the founder of EFT about using EFT for the treatment of Post Traumatic Stress Disorder. It is a very powerful demonstration of what is possible using this apparently absurd technique.
The video is both moving and disturbing, featuring a group of veterans of the Vietnam war and the war in Iraq. As well as the experience of the veterans and EFT practitioners there is also commentary from a psychologist and psychiatrist and some research findings done on the participants to give a mental health professionals viewpoint.
