Researchers were interested in evaluating the effect of aromatherapy with ginger essential oil on vomiting episodes after cardiac surgery. Patients were divided into two groups: (1) control, and (2) aromatherapy and exposed to the intervention prior to intubation. Incidence of vomiting episodes were recorded for 4 hours after the surgery and compared between groups.
