Ginger may improve nausea and vomiting during pregnancy

In September 2018 researchers from Bahrain and Fiji published their review of the medical scientific literature to assess the effect of different interventions in treating nausea and vomiting in pregnancy. A total of 50 studies were included in the review. Results showed acupuncture, chamomile, dimenhydrinate, doxylamine/vitamin B6, ginger, quince, metoclopramide and vitamin B6 were associated with reduced nausea when compared to placebo. Of these interventions, ginger and vitamin B6 were also associated with better vomiting control and less incidence of adverse events. However, it should be noted that adequate evidence exists only for ginger and the quality of evidence for this comparison is moderate. Strength of evidence for all other comparisons is very low.
