"The cause of any negative emotion is an energy system disorder in our body"

EFT technique was put in motion by Gary Craig, an engineer by the Stanford University; later, he got a diploma in NLP, Neuro-Linguistic Programming, and he ended up inventing EFT, after his research on what Dr. Roger Callahan's discovered. He recons that EFT is a combination of 2 types of sciences, acupuncture and body and mind medicine. Gary Craig says EFT is the emotional version of acupuncture.

EFT is a technique which allows us to liberate in a quick way of any disorder affecting our physic, psychic or emotional health.
In 1 or 2 EFT (tapping) sessions, we get rid of blockages, pain, or long-lasting emotions.
The method is very simple and painless; I say no pain because healing a present or past situation we need to talk about it and the fact of re-talking generally revives pain.

The miracle of EFT is that not only pain is avoided, but that it will disappear once and forever. EFT can heal nearly everything; the only condition (sine qua non) is that it must be your decision and your desire.

Here follows a short list
Allergies: psoriasis, food, mite, etc.
Physical pain: backache, headache, arthritis, etc.
Emotional blockage: loss of self esteem, depression, phobias, stress, insomnia, dependencies, etc.
