The Effect of Sweet Orange Aromatherapy on Anxiety and Pulse Level of Nurse Students

The sweet orange essential oil used in the study was prepared by the Food Engineering Department of Fırat University. To obtain the essential oil used for aromatherapy in this study, the peels of Citrus sinensis sweet oranges were utilized. The orange peels were cut into small pieces of approximately 3-5 mm in size, placed into a boiling flask, and distilled water was added. Based on the analysis results, the percentage composition of the total essential oil fatty acids was determined. The chemical composition analysis revealed that D-limonene was the major component, comprising 90% of the total oil. The oil is 100% pure essential oil, containing up to 90% D-limonene, along with citral and linalool. A cotton ball infused with three drops of sweet orange essential oil was held 4 to 5 cm away from the student's nose, and they were instructed to breathe slowly for five minutes. After this, the students were asked to perform IV cannulation on the patient.
