No one knows exactly where oranges come from, although Southeast Asia is believed to be their first home. The ancient Greeks and Romans knew about oranges. It is possible that oranges were carried from India to Western Asia, and then to all of Europe. The Spaniards took the sour orange to the West Indies and from there to Florida, in America. Today, they are grown in most of the warmer parts of the world and are the most important fresh fruit in international trade.

There are three different kinds of oranges: the sweet or common orange, the mandarin orange, and the sour or bitter orange. One type of sweet orange is called the blood orange. It has a pulp with a deep red color. This type of orange is grown mostly in the Mediterranean region. Mandarin oranges are grown mostly in Florida. Sour oranges are grown almost everywhere, but Spain grows most of the sour oranges used for trade. These sour oranges are mainly used to make marmalade, but they can be put to many other interesting uses- from making medicine to creating perfumes.

Oranges have many medicinal values. Oranges are the fruit with the greatest concentration of vitamin C. The thick, oily and bitter skin does not allow any insects to get into an orange. Many kinds of useful oils can be extracted from this thick skin. Oranges are healthy and delicious.
