Ginger is also known as rhizome of ginger (zingiber offcinale) can be used as alternative nonpharmacological therapy to increase gastric and peristaltic muscle tone through antiserotonergic and anticholinergic pathways. Literature searching was conducted using online database Pubmed, Cochrane, Springer, EBSCO, and ProQUEST. Article searching was conducted according to keywords, criteria of inclusion, and exclusion that have been determined. Furthermore, it is critically reviewed using the instruments already available. The type of study is evidence based medicine. This study aimed to find out evidence that ginger can be used as alternative nonpharmacological therapy to reduce nausea and vomiting in pregnancy. Ginger is more effective and safe to reduce symptoms of nausea vomiting during pregnancy. But the results still have high heterogeneity due to variations in the study. Ginger can be used as an alternative non-pharmacological therapy that helps reduce symptoms of NVP (nausea and vomiting in pregnancy). However, further research is needed to obtain clear evidence of the effects of ginger therapy in reducing the symptoms of NVP.
