Mark Weisberg writes a paper that explores Fifty Years of Hypnosis in Medicine and Clinical Health Psychology: A Synthesis of Cultural Crosscurrents (web) . . . the abstract is as follows:

In 2008, the 50th anniversary of ASCH, hypnosis is used increasingly
for healthcare applications in hospitals, clinics, and psychotherapy
practice. A substantial body of research demonstrates the efficacy of
hypnosis as part of the integrative treatment of many conditions that
traditional medicine has found difficult to treat (e.g., Pinnell &
Covino, 2000; Elkins, Jensen, & Patterson, 2007). The practice of
hypnosis in healthcare has been altered and centrally influenced by the
rapid growth of technological medicine in the 1950’s, the AIDS epidemic
and development of psychoneuroimmunology, revolutionary developments in
genetics and neuroimaging technology, and the progression from
alternative to integrative medicine. We have come to develop more
detailed expectations about the beneficial effects of hypnotic
interventions for health problems. We have also come to know that in
these populations hypnosis can lead not only to reduced anxiety but
also specifically altered physiological parameters.

Granted, Weisberg’s focus is narrow and does not adequately include or portray the valuable work of professional hypnotists outside the licensed barrier, but the piece is very much worth the read.

All the best,
Brian
