compared with baseline, the decrease in the visual analogue scores of post-therapy nausea in the ginger group
was significantly greater than that for the vitamin B6 group (p ¼ 0.024). The number of vomiting episodes decreased in
both groups, and there was no significant difference between the groups. In the ginger group, 29/35 women reported an
improvement in nausea symptoms, compared with 23/34 women in the vitamin B6 group (p ¼ 0.52).
Conclusion: ginger is more effective than vitamin B6 for relieving the severity of nausea, and is equally effective for
decreasing the number of vomiting episodes in early pregnancy.
