Implementing standardised rhodes index to measure the efficacy of ginger extract (Zingiber officinale) in pregnancy induced nausea and vomiting

Background: Although nausea and vomiting are natural signs of pregnancy affecting about half the pregnant women during their first trimester of pregnancy, it is unpleasant and difficult symptom to deal with. Considering the fact that medication during pregnancy is not advised, we decided to study the efficacy of a natural product to control nausea and vomiting during early pregnancy. Our study was directed to estimate the efficacy of ginger extract (Zingiber officinale) in pregnancy induced nausea and vomiting.Methods: A total of 30 women with pregnancy of 4-16 weeks, suffering from nausea and vomiting were included in this study (n=30). Subjects were given ginger extract 250mg, to be taken 3 times a day half an hour before food for 1 week. Severity of vomiting was assessed by Rhodes Index of Nausea and Vomiting by the patients. Baseline scores were compared with the score at the end of 7 day. The findings were analysed statistically.Results: Effect with the ginger extract in pregnancy induced nausea and vomiting was assessed at the end of treatment (day 7) and compared with the baseline values. Four patients reported symptoms of heartburn. Otherwise, there were no other reports of any adverse effects. The results showed significance (p <0.005).Conclusions: Ginger extract (Zingiber officinale) helps in reducing severity and frequency of pregnancy induced nausea and vomiting. Therefore, we conclude that ginger extract can be used for mild to moderate nausea and vomiting induced by pregnancy during first trimester
