Orange oil is an essential oil produced by cells within the rind of an orange. Well-known for its uplifting properties, it is soothing to the mind and can help to relieve stress. It is refreshing and relaxing, and commonly used for the treatment of anxiety.

Oranges are native to India and China. Since ancient times, oranges have been used in Chinese medicine to treat colds, coughs, and anorexia. Due to the scarcity and high expense of oranges until the late 17th century, they were only used for their medical properties in Europe and not for human consumption.
