Sour orange (Citrus aurantium)

Description

“Pet poisonous” - Toxic to Dogs Bitter orange, Seville orange, sour orange, bigarade orange, or marmalade orange refers to a citrus tree (Citrus × aurantium) and its fruit. It is native to southeast Asia, and has been spread by humans to many parts of the world. Wild trees are found near small streams in generally secluded and wooded parts of Florida and The Bahamas after it was introduced to the area from Spain where it had been introduced and cultivated heavily beginning in the 10th century by the Moors. Many varieties of bitter orange are used for their essential oil, and are found in perfume, used as a flavoring or as a solvent. The Seville orange variety is used in the production of marmalade. Bitter orange is also employed in herbal medicine as a stimulant and appetite suppressant, due to its active ingredient, synephrine. Bitter orange supplements have been linked to a number of serious side effects and deaths, and consumer groups advocate that people avoid using the fruit medically. It is still not concluded if bitter orange affects medical conditions of heart and cardiovascular organs, by itself or in formulae with other substances. Standard reference materials are released concerning the properties in bitter orange by the National Institute of Standards and Technology (NIST), for ground fruit, extract and solid oral dosage form, along with those packaged together into one item.
