Bitter orange

Bitter orange, Seville orange, sour orange, bigarade orange, or marmalade orange refers to a citrus tree 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. Bitter orange is marketed as a dietary supplement because of its stimulant properties, although safety data are lacking and it has been linked to a range of harmful side effects including strokes and heart attacks.
