Onion (Allium cepa) - Interesting facts

Allium is a diverse genus of bulbous perennials that includes such plants as onions, garlic, chives, leeks, society garlic and giant ornamental onions. They all have relatively high concentrations of sulfur compounds which give them their unique smells and flavors. When the plant tissue is damaged some of these sulfur compounds are released, which explains why we cry when we cut onions. The sulfur compounds can dissolve in our tears, where it forms sulfuric acid. In response to the acid in our tears, we blink and produce more tears. This gives the impression that cutting onions makes us cry.
