Onion is an important crop used raw, as a vegetable and spice all over the world. It is a bulbous biennial or perennial herb. Bulbs are formed by the attachment of swollen leaf bases to the underground part of stem vegetable crops.
The exact origin of the onion is not known. It is likely the onion was cultivated in Asia in 3000 BC. The onion was taken from Asia to Greece and Egypt. The onion is often featured in hieroglyphs and designs on the Pyramids. The Egyptians building the Pyramids would receive daily rations which would always include the onion. It was believed that onions could ward off illness and would promote greater strength. Onions would also be laid inside mausolea as food and medicine for those journeying to the hereafter. The onion skin was seen as a symbol of eternity and onion itself as an offering to the gods of the River Nile.
