Clinical hypnosis is the interaction of a hypnotist with the sub-conscious mind of the person being hypnotized, which plays an integral role in his treatment. In most cases, only qualified physicians can perform such hypnosis since they have the required knowledge about the mental state of a patient at a given time.

Of late, clinical hypnosis has assumed tremendous importance in view of the fact that people visit trained hypnotists to tackle their problems like smoking, drinking and various others. This method of hypnosis at a clinic is proved to be successful to control obesity as well.
