There is considerable academic research demonstrating the efficacy of hypnotherapy:

“Our results revealed a signifi- cant effect size (D = 1.20), indicating that surgical patients in hypnosis treatment groups had better out- comes than 89% of patients in control groups. No significant differences were found between clinical out- come categories or between methods of the induction of hypnosis. These results support the position that hyp- nosis is an effective adjunctive procedure for a wide variety of surgical patients.”


Hypnosis helps healing: Surgical wounds mend faster

William J. Cromie, Harvard Gazette

“Six weeks after the fracture, those in the hypnosis group showed the equivalent of eight and a half weeks of healing.”



P.J. Whorwell, Alison Prior, E.B. Faragher, Department of Medicine, University Hospital of South Manchester, Manchester M20 8LR, United Kingdom

“30 patients with severe refractory irritable-bowel syndrome were randomly allocated to treatment with either hypnotherapy or psychotherapy and placebo. The psychotherapy patients showed a small but significant improvement in abdominal pain, abdominal distension, and general well-being but not in bowel habit. The hypnotherapy patients showed a dramatic improvement in all features, the difference between the two groups being highly significant. In the hypnotherapy group no relapses were recorded during the 3-month follow-up period, and no substitution symptoms were observed.”


Hypnotherapy in the Treatment of Chronic Combat-Related PTSD Patients Suffering From Insomnia: A Randomized, Zolpidem-Controlled Clinical Trial

Eitan G. Abramowitz, Yoram Barak, Irit Ben-Avi und Haim Y. Knobler  International Journal of Clinical and Experimental Hypnosis

“There was a significant main effect of the hypnotherapy treatment with PTSD symptoms as measured by the Posttraumatic Disorder Scale. This effect was preserved at follow-up 1 month later. Additional benefits for the hypnotherapy group were decreases in intrusion and avoidance reactions and improvement in all sleep variables assessed.”


Hypnosis and relaxation therapies

Andrew Vickers,1 Catherine Zollman, and David K Payne,                                   Western Journal of Medicine

“Evidence from randomized controlled trials indicates that hypnosis, relaxation, and meditation techniques can reduce anxiety, particularly that related to stressful situations, such as receiving chemotherapy… A systematic review showed that hypnosis enhances the effects of cognitive behavioral therapy for conditions such as phobia, obesity, and anxiety.”

“Overall, the findings of research indicate that hypnosis used as an adjunctive to other medical or psychological interventions increases the efficacy and/or efficiency of these interventions. Moreover, hypnosis efficacy is well established in certain clinical applications, especially pain management and other medical conditions, and there is acceptable evidence of its efficacy in treating depression, sleep disorders, smoking cessation, obesity, asthma, and enuresis in children.”



Treating anxiety with self-hypnosis and relaxation

Lucy M. O’Neill, Amanda J. Barnier andProfessor Kevin McConkey,     Contemporary Hypnosis

“Twenty individuals who presented for treatment for ‘stress, anxiety, and worry’ were assessed (for anxiety and self-hypnotizability), exposed to a 28-day treatment programme (which involved daily measures of outcome and process variables), and re-assessed (for anxiety). It was found that both self-hypnosis and relaxation alleviated anxiety pre- to post-treatment…throughout treatment self-hypnosis rather than relaxation was associated with a greater sense of treatment efficacy and expectation and with a greater sense of cognitive and physical change.”
