Onions are packed with plant chemicals called flavonoids, and in particular quercetin, that’s been linked to reducing heart disease. In fact, onions have been singled out as one of the few vegetables and fruits that contribute to the significant reduction of heart disease.

Onions have many health benefits and chemical compounds found in onions have been suggested to have anti-inflammatory, anti-cholesterol, anti-cancer, and antioxidant properties.

In many parts of the world, onions are used to heal blisters and boils as well as treatment for certain animal stings.  The anti bacterial properties of the onion make it popular as a treatment for sore throats and minor infections.

If you have been troubled by tears when peeling & slicing onions, try chilling them before use, or cutting under running water.
