Summary: In a randomized, placebo-controlled study involving 120 patients who underwent major gynecologic surgery, results indicate that supplementation with ginger one hour before surgery may be effective in the prevention of postoperative nausea and vomiting.
The patients were randomized to two capsules of ginger powder (0.5 g of ginger in one capsule) or placebo (n=60), one hour before undergoing major gynecologic surgery.
Visual analog nausea score and frequency of vomiting were evaluated 2, 6, 12, and 24 hours post operation. The incidence and frequency of vomiting was lower in the ginger-supplemented group than in the placebo group.
Additionally, the visual analog nausea scores were lower in the ginger-supplemented group, compared with the placebo group. Thus, the authors of this study conclude, "Ginger has efficacy in prevention of nausea and vomiting after major gynecologic surgery."
