Onion (Allium cepa) is a plant that is grown worldwide. The onion bulb is commonly eaten as food. Onion bulb and extract are also used to make medicine.
Onions vary in size, shape, color, and flavor. The most common types are red, yellow, and white onions. The taste of these vegetables can range from sweet and juicy to sharp, spicy, and pungent, often depending on the season in which people grow and consume them.
As a good source of vitamin C, onions may support the building and maintenance of collagen. Collagen provides structure to skin and hair.
It is presumed our predecessors discovered and started eating wild onions very early – long before farming or even writing was invented. Very likely, this humble vegetable was a staple in the prehistoric diet.
