[Is ginger a relevant antiemetic for postoperative nausea and vomiting?].

Objective: Ginger (Zingiber officinale) has traditionally been used in China for gastrointestinal symptoms, including nausea and vomiting. A recent systematic review on the possible antiemetic effect of ginger for various indications, including PONV, morning sickness, and motion sickness, concluded that ginger was a promising antiemetic herbal remedy, but the clinical data were insufficient to draw firm conclusions. Since that publication, additional data has accumulated and thus an updated meta-analysis was performed.
