Franz Mesmer (1734–1815) believed that there is a magnetic force or "fluid" called "animal magnetism" within the universe that influences the health of the human body. He experimented with magnets to impact this field in order to produce healing. By around 1774, he had concluded that the same effect could be created by passing the hands in front of the subject's body, later referred to as making "Mesmeric passes". The word "mesmerize", formed from the last name of Franz Mesmer, was intentionally used to separate practitioners of mesmerism from the various "fluid" and "magnetic" theories included within the label "magnetism".
We know it is hard to sort out all the different claims made by some so-called “hypnosis schools and boards.” Stay away from “distance learning” or correspondence courses that claim to certify you as a clinical hypnotherapist. Hypnosis and hypnotherapy is a healing art based on scientific methods. Only basic hypnotherapy theory can be obtained from the right books or videos. Effectiveness is unlikely without live demonstrations, in-depth and advanced discussion, question and answer opportunities and supervised clinical practice. Just as correspondence courses are inappropriate for counselors, medical doctors and massage therapists, they are wrong for people who want to be effective and successful clinical hypnotherapists.
Hypnosis is not a psychotherapeutic treatment or a form of psychotherapy, but rather a tool or procedure that helps facilitate various types of therapies and medical or psychological treatments. Only trained health care providers certified in clinical hypnosis can decide, with their patient, if hypnosis should be used along with other treatments. As with psychotherapy, the length of hypnosis treatment varies, depending on the complexity of the problem.
