How much truth is there to the belief that small sips of ginger ale can help combat nausea?

While there has been a fair amount of scientific literature showing that a teaspoon of ground ginger is a pretty powerful dose against nausea, the same can not be said for ginger ale.
Most commercial varieties of the beverage do not contain any real ginger. They instead use ginger flavoring.
You are much better off dissolving a teaspoon of ground ginger into a cup of a hot tea than sipping on Canada Dry (which is what most people reach for to combat nausea). Even ginger ales made with real ginger don’t usually deliver enough of it to have any effect.
