Ginger Reduces Nausea and Vomiting During Pregnancy.
A comprehensive Cochrane overview of 16 clinical studies looked at the impact of ginger on pregnancy related nausea and vomiting and concluded that data on the subject was limited and inconsistent.
Ginger (Zingiber officinale) is commonly recommended as a folk remedy for pregnancy related nausea and vomiting. Websites such as fitpregnancy.com recommend ginger to expectant moms who are experiencing nausea and vomiting and especially for those who want to keep their pregnancy a secret.
A Cochrane review published in 2014 looked at studies evaluating all interventions to help nausea and vomiting in early pregnancy. (1) The authors justified the need for the review given the economic burden and negative impact on quality of life caused by pregnancy related nausea and vomiting.
The review included studies evaluating the effect of ginger on nausea and vomiting during pregnancy. The meta-analysis looked at data from 1706 pregnant women who were enrolled in 7 studies on ginger versus placebo, 1 study on ginger versus P6 acupressure, 1 study on chamomile versus ginger, 4 studies on ginger versus B6, 1 study on the anti-nausea tablet metoclopramide versus ginger, 1 study looking at dimenhydrinate tablets versus ginger and 1 study on doxinate tablets versus placebo.
Only three out of seven studies comparing ginger with placebo for the management of pregnancy related nausea and vomiting favored ginger to placebo.
Ginger was well tolerated and deemed to be ‘harmless’ by the reviewers.
Overall the authors of the Cochrane review concluded that the scientific evidence on the subject was ‘limited and inconclusive’.
In summary, there is no convincing evidence to support the use of ginger to reduce pregnancy related nausea and vomiting.
