EFT Madness (Emotional Freedom Technique). Does it work?

I like to put something out here occasionally that is non political or about economics but which I have found interesting.

I found this video about EFT - Emotional Freedom Technique - to be quite fascinating.

To me EFT is absolutely crazy, in fact, I always considered it to be a scam, but now a district within the British NHS is offering EFT to its patients. 

Professor Dr Tony Stewart's research (he is a NHS consultant) showed that EFT can be effective in only 4 or 5 sessions compared to CBT which might need up to 20 sessions. He now trains other doctors in the technique, including EFT Matrix Reprinting, which is a way of resolving childhood trauma. 

EFT is also being used on physical illnesses, including chronic ones. 

I'm open minded on it at the moment.
