Sweet orange trees originated in the tropical regions of Asia, specifically in the eastern region of Assam in India, northern Myanmar, and western Yunnan in China.
Arab empire expansion and trade helped the orange tree variety to reach Europe and other countries in the world. Additionally, the Spanish explorers introduced this variety to the Americas in the 15 century. Furthermore, British colonizers brought this citrus fruit to Australia in the 18th century.
Considered as not palatable because of its taste, some herbalists used orange fruit as a medicinal syrup. For example, the British Royal Navy used orange to prevent scurvy, a disease caused by a lack of vitamin C.
Overall, the majority of this refreshing drink comes from the top citrus producer in the world with Brazil sitting on the number one spot because of its yearly 1.3 million tons of orange juice production. The United States, Mexico, the European Union, and South Africa follow distantly.
