Known also with its botanical name Allium Cepa, the onion is one of the oldest vegetables in the world, known to the ancient Egyptians. It seems that the ancient Canaanites (the inhabitants of that Middle Eastern region, now modern day Lebanon, Israel, and the western parts of Syria and Jordan), over 5,000 years ago, knew the techniques of cultivation and use in the kitchen. In ancient Egypt, on the other hand, the onion became an object of worship because of its spherical shape and concentric rings which, for worshiping the dead from local populations, referred to extraterrestrial life after death. The ancient Greeks and Romans, on the other hand, were the first to recognise and appreciate its therapeutic properties.
