“…In a series of studies on medical students in both the UK and the USA, students experiencing stress showed immunosuppression which was buffered by interventions including hypnosis (Kiecolt-Glaser, Glaser, Strain, Stout, Tarr, Holliday and Speicher, 1986;Glaser, Rice, Speicher, Stout and Kiecolt-Glaser, 1986;Gruzelier, Smith, Nagy and Henderson, 2001b;Naito, Laidlaw, Henderson, Farahani, Dwivedi and Gruzelier, 2003). An important component of treatment has been guided imagery, mostly in the context of hypnosis, which has been a technique used clinically with some research backing for its efficacy (Fox, Henderson, Barton, Champion, Rollin and Catalan, 1999;Gruzelier, Levy, Williams and Henderson, 2001a;Gruzelier, 2002a). In the Gruzelier et al (2001b) study, groups having immune imagery were directly compared to those having hypnosis without immune imagery and a control group (Gruzelier et al, 2001a).…”
