Treatment of plantar warts using hypnosis? … No!

In this case study, the authors describe an adult patient who struggled with persistent warts on the plantar surface of the foot for several years. All medical therapies were exhausted, so the patient turned to medical hypnosis as a last resort.

The patient experienced complete resolution of all his warts after three sessions of medical hypnosis. The suggestions used in the treatment included:

• strengthening the immune system,
• increasing blood flow in the foot,
• visualizing immune mechanisms destroying infected cells,
• the regrowth of healthy tissue.

After 3 years, the authors are still in contact with the patient, and he reports no recurrence of the disease.

The authors concluded that this case report adds to the existing body of the literature supporting the use of medical hypnosis in the treatment of warts. It demonstrates that medical hypnosis can be a valuable complementary or alternative treatment option for patients with persistent warts who have not responded to conventional therapies. It also highlights the need for further research to better understand the mechanisms by which hypnosis influences the resolution of warts and to identify the most effective types of suggestions for treatment.

Oh, dear!

Warts are viral infections. They can persist for months and years and disappear suddenly without apparent reason. What the authors of this case report observed is exactly this phenomenon of spontaneous recovery. There is no sound evidence that hypnotherapy or any similar treatment will speed up the disappearance of warts.

Many years ago, we did a trial of ‘distant healing’ for warts. It confirmed the ineffectiveness of this approach:

Purpose: Distant healing, a treatment that is transmitted by a healer to a patient at another location, is widely used, although good scientific evidence of its efficacy is sparse. This trial was aimed at assessing the efficacy of one form of distant healing on common skin warts.

Subjects and methods: A total of 84 patients with warts were randomly assigned either to a group that received 6 weeks of distant healing by one of 10 experienced healers or to a control group that received a similar preliminary assessment but no distant healing. The primary outcomes were the number of warts and their mean size at the end of the treatment period. Secondary outcomes were the change in Hospital Anxiety and Depression Scale and patients’ subjective experiences. Both the patients and the evaluator were blinded to group assignment.

Results: The baseline characteristics of the patients were similar in the distant healing (n = 41) and control groups (n = 43). The mean number and size of warts per person did not change significantly during the study. The number of warts increased by 0.2 in the healing group and decreased by 1.1 in the control group (difference [healing to control] = -1.3; 95% confidence interval = -1.0 to 3.6, P = 0.25). Six patients in the distant healing group and 8 in the control group reported a subjective improvement (P = 0.63). There were no significant between-group differences in the depression and anxiety scores.

Conclusion: Distant healing from experienced healers had no effect on the number or size of patients’ warts.

My conclusion of the above case study is therefore very different from that of the original authors:

This case report adds nothing to the existing body of the literature on medical hypnosis or on the treatment of warts other than misleading the public.
