This research on Ginger (Zingiber officinale) reviews two different studies done on Ginger to explore its effectiveness in the treatment of postoperative nausea and vomiting.  In the first, ginger, cardamom and tarragon we blended together in equal parts. While in the second only ginger was used in inhalation.  Both studies showed success in the alleviation of postoperative nausea and vomiting.

A trial of a mixture of three essential oils in the treatment of postoperative nausea and vomiting.

E. de Pradier

Summary

The management of postoperative nausea and vomiting (PONV) that occurs in 30% of all surgical cases is indispensable for a rapid recovery, patient comfort and the overall image of general anesthesia. Currently, allopathic drugs proposed in surgery include major drugs such as morphine as well as analgesics of class IIB such as Nefopam and Tramadol. We wanted to demonstrate that it is possible to treat these negative effects of anesthesia with a mixture of three essential oils via percutaneous application on the anterolateral aspect of the neck.

This study comprised of 73 cases and used a mixture of Zingiber officinale (ginger), Elettaria cardamomum (cardamom) and Artemisia dracunculus (tarragon) essential oils in equal parts.

The results were collected approximately 30 min following application as soon as the symptoms appeared in the theatre recovery room. Seventy five percent of cases had a favourable outcome. The best results were obtained with patients who had received a single drug that provoked the symptoms. In all other cases, results were reduced to a 50% success rate.

Abstract

Background: The purpose of this study was to examine the effectiveness of aromatherapy with ginger essential oil on nausea and vomiting in abdominal surgery patients.

Method: This was a quasi-experimental study with a non-equivalent control group and repeated measures. The experimental group (n = 30) received ginger essential oil inhalation. The placebo control group (n = 30) received normal saline inhalation. The level of postoperative nausea and vomiting was measured using a Korean version of the Index of Nausea, Vomiting, and Retching (INVR) at baseline and at 6, 12, and 24 h after aromatherapy administration. The data were collected from July 23 to August 22, 2012.

Results: Nausea and vomiting scores were significantly lower in the experimental group with ginger essential oil inhalation than those in the placebo control group with normal saline. In the experimental group, the nausea and vomiting scores decreased considerably in the first 6 h after inhaled aromatherapy with ginger essential oil.

Conclusion: Findings indicate that ginger essential oil inhalation has implications for alleviating postoperative nausea and vomiting in abdominal surgery patients.
