This study measured the responses of 17 cancer hospice patients to humidified essential lavender oil aromatherapy. Vital signs as well as levels of pain, anxiety, depression, and sense of well-being were measured (using 11-point verbal analogs). Each subject was measured on three different days before and after a 60-minute session consisting of (1) no treatment (control); (2) water humidification (control); or (3) 3-percent lavender aromatherapy. Results reflected a positive, yet small, change in blood pressure and pulse, pain, anxiety, depression, and sense of well-being after both the humidified water treatment and the lavender treatment. Following the control session (no treatment), there was also slight improvement in vital signs, depression, and sense of well-being, but not in pain or anxiety levels.
