A traditional remedy to ease a fever or stomach upset is to take a hot onion and add a large spoonful of sugar to it. This will sweeten the solution and give it more of a taste. Other methods, such as boiling the onion in water, have been used to add sweetness to this solution.

This has been used to treat a variety of stomach problems, not just fevers. Onion and sugar is a popular remedy for colds and flu, as well as coughs and congestion. If you haven’t tried it, I’d highly recommend checking it out.
