Aromatherapy use in hospital admissions

There were 10,262 hospital admissions during the study time frame in which nurse-delivered aromatherapy was part of patient care at 10 hospitals in Minnesota and western Wisconsin. Essential oils generally resulted in significant clinical improvements based on their intended use. Sweet marjoram was the most effective for decreasing pain, while lavender and sweet marjoram decreased patient anxiety, and ginger decreased nausea. In addition, each oil also showed ancillary benefits for other symptoms.
