Already known and cultivated in the ancient Asia, from where it was brought to Europe. According to the Egyptian hieroglyphics, onion was for sure grown on the outskirts of Egyptian cities during the reign of Ramses II (1292-1234 B.C.).

It has been proven that Greeks ate onions raw while watching theatre plays, which ? fortunately ? took place in the open air, so it didn?t expose those who were less enthusiastic about this vegetable to its intense smell. At present, the biggest onion producers are Egypt, Spain and Hungary. In Poland onion is grown in several varieties, mainly dako, wolska, sochaczewska, żytawska, rawska, as well as Dutch red and white ? considered as the most durable, grown for winter storage.

The therapeutic properties of onion were already known in folk medicine thousands of years ago. Undoubtedly, the vegetable deserves at least one monument for all its beneficial properties.
