NCT ID NCT05714995
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether combining aromatherapy (smelling essential oils) with hypnosis can help cancer patients feel more comfortable during uncomfortable procedures like blood draws or dressing changes. About 66 adults with cancer will be randomly assigned to receive hypnosis alone or hypnosis plus aromatherapy. Researchers will measure comfort levels before and after the procedures.
