ELI5: Why Ginger Ale is good at relieving stomach issues and other sodas aren't.
gpt
Ginger Ale contains Ginger. More specifically, ginger root, which is a natural anti-nausea remedy. The anti-nausea drug Gravol is made with Ginger Root as well. And Ginger pills are often administered to help with sea-sickness.

And contrary to what some people believe, the carbonation does not help, in fact it worsens nausea by adding more gas and pressure, and can cause vomiting, so it's best to let the soda go relatively flat.
