This is a great home remedy that I make any time my toddler has a tummy ache. Works for adults too of course. It takes care of nausea and vomiting almost instantly, and tastes good.
1 cup hot water
1/4 teaspoon grated ginger or ginger juice
1 teaspoon raw honey
Pour hot water over ginger and let stand for 3 minutes, then stir in honey. Drink while still warm for maximum benefit.
