Inhaling ginger essence relieves postoperative nausea and vomiting

Ginger root

After nephrectomy (a surgical procedure to remove all or part of a kidney), 2 drops of ginger essence to a 2 × 2-inch gauze was attached to the patients’ collars to allow patients to inhale the evaporated essence and then repeated every 30 min for 2 hours. The results showed significantly lower nausea intensity and number of vomiting episodes after the surgery compared to a control group.
