Effects of Aromatherapy with Essential Oils on Anxiety and Depression in Perioperative Patients with Pancreatic Cancer

The objective of this study is to investigate whether aromatherapy essential oils are effective in alleviating anxiety and depression in participants undergoing perioperative pancreatic cancer treatment. Researchers compared aromatherapy essential oils with a placebo (a substance that appears similar but contains no essential oils) to determine their efficacy in reducing anxiety and depression in these participants. Participants were required to undergo aromatherapy for 2 hours daily over a period of 15 days. Assessments of anxiety and depression were conducted one day before surgery, 14 days after surgery, and 42 days after surgery, with their scores recorded accordingly.
