Effects of Ginger and Expectations on Symptoms of Nausea in a Balanced Placebo Design
Figure 4
Electrogastrogram (EGG) in male and female participants that received ginger or placebo.
EGG was evaluated as the ratio between normal activity (2.5 to 3.75 cycles per minute, cpm) and activity in the tachygastria band (4 to 9.75 cpm), and with increasing nausea the ratio usually falls below 1. Data segments were recorded at baseline, twice after drug application, and after rotation. The constant fall of the ratio from baseline to post rotation was not different between men and women.
