Grapefruit is a refreshing and revitalizing essential oil that can help boost the body's feelings of energy and happiness. 
Grapefruit (Citrus paradisi) belongs to the Rutaceae plant family; it is thought to be a hybrid of pumello fruit (Citrus maxima) and sweet orange (Citrus sinensis). Grapefruit is native to tropical Asia; it is believed that the pumello fruit was brought to Europe by early medieval Arab traders and cross-pollinated with sweet orange in the West Indies, where both plant species were introduced, resulting in the birth of the grapefruit. However, there are no records to verify the grapefruit's exact origins.
Similarly, there are no clear records indicating the historic uses of this plant oil; however, many believe that grapefruit oil was used in baths to treat the skin, enhance the appearance of people's hair, and possibly as a cleaning agent.The cultivated grapefruit tree grows to over 33 feet in height; it has green, glossy leaves, large, round, yellow fruits and white, aromatic flowers which are star-shaped. Grapefruit is known as a 'happy' oil due to its uplifting qualities and is liked by children for this reason; it is said to improve concentration and self-confidence. It is used in aromatherapy spa treatments to improve lymphatic drainage and to ease muscle stiffness, by dispersing lactic acids.
California is the main producer of grapefruit essential oil. In Israel, grapefruit is used for many ailments and is treated with the same respect that lavender (Lavandula angustifolia) is given by the English.
