ginger - Medical uses - Nausea
Ginger has been found effective by multiple studies for treating nausea caused by seasickness, morning sickness and chemotherapy, though ginger was not found superior over a placebo for post-operative nausea.

Modern research on nausea and motion sickness used approximately 1 gram of ginger powder daily. Though there are claims for efficacy in all causes of nausea, the Physicians Desk Reference recommends against taking ginger root for morning sickness commonly associated with pregnancy due to possible mutagenic effects, though Chinese women have traditionally used ginger root during pregnancy to combat morning sickness and the Natural Medicines Comprehensive Database states that it is likely safe for use in pregnancy when consumed in food-amounts.
