According to a systematic review and meta-analysis, pregnant women who experience nausea and vomiting during pregnancy can use ginger to reduce their symptoms to the same extent as Vitamin B6. Rakhi Gaur et al. aimed to explore effects of Vitamin B6 and Ginger to alleviate vomiting and nausea in pregnant females.

Relevant studies were found by a thorough search of the gray literature and the electronic databases SCOPUS, Embase, and PubMed. Software called Review Manager (Version 5.3) was used for the meta-analysis. Additionally, publication bias was examined using funnel plots, and the source of heterogeneity was examined using a leave-one-out analysis. A total of 819 participants were incorporated.

The findings showed that, in comparison to Vitamin B6, Ginger had no noticeable effect on nausea scores (Standard mean deviation [SMD] −0.15) and vomiting scores (SMD 0.05) were witnessed. However, compared to Ginger, the Vitamin B6 intervention significantly minimized the overall scores of nausea and vomiting during pregnancy  (SMD 0.36).

Thus, Ginger can be utilized to treat morning sickness in pregnant women in a way similar to how Vitamin B6 works.
