What Is Orange Oil Good For?

Orange oil producers derive orange extract from a variety of different species, each of which offers its own unique properties. Most orange oil comes from the inner white skin or rind of the orange, though the leaves, bark and flowers of the tree can also be used to produce oil. Consumers will find this product sold under the name of bitter orange, orange extract or orange oil.

Types

Different types of oranges produce a variety of oils and extracts. Much of the oil used for alternative medicinal needs throughout the world comes from the bitter or sour orange. This species grows primarily in Southeast Asia, the Middle East and Africa. The sweet orange grows worldwide, including the U.S., and is primarily used for non-health purposes.

Applications

Scientists and researchers have found well-established links between orange oil and pest control. According to a 2007 study by the Entomological Society of America, orange oil serves as a highly-effective termiticide. It's highly toxic to insects, yet protects workers from the health effects of chemical exposure. The Iowa State University Department of Entomology also touts the benefits of orange oil as an all-natural alternative to chemicals for those looking to exterminate German cockroaches.

Uses

Manufacturers rely on different forms of orange oil to flavor candies, food, drinks and liqueur. The oil from the sweet orange is also commonly used as a food preservative and flavoring, while oil from the mandarin orange is not typically suitable for flavoring food products. Oil from the orange seed can be used to make both cooking oil and cattle feed, while all forms of orange oil serve as popular perfume ingredients.

Considerations

According to the Purdue University Center for New Crops and Plant Products, orange oil has long been used in traditional folk medicine, and some forms still serve as a popular antiseptic in Africa. A 2009 USDA study found that orange oil improves some gastrointestinal disorders in sheep and goats, but further research is needed before this remedy can be applied to humans. In 2002, the Indian Journal of Experimental Biology published a study showing that orange oil may shrink tumors in lab animals. Despite these results, little reliable evidence supports orange oil use in humans.

Warning

Some manufacturers use orange oil in weight loss products due to the oil's similarities to ephedra. While study results are mixed regarding orange oil's effectiveness as a weight loss aid, the National Institute of Standards and Technology warns of dangers associated with consuming the supplement in this way. Just like ephedra, some forms of orange oil may lead to serious, long-term health problems or even death. Orange oil should not in any way be considered a safer or more natural alternative to ephedra-based weight loss products.
