The name "bitter orange", also known as Seville orange, sour orange, bigarade orange, and marmalade orange, refers to a citrus tree (Citrus aurantium) and its fruit. Many varieties of bitter orange are utilized for their essential oil, which is used in perfume and as a flavoring. Bitter orange is also employed in herbal medicine as a stimulant and appetite suppressant. Slivers of the rind are used to give marmalade its characteristic bitter taste.

After the U.S. Food and Drug Administration banned the herbal stimulant ephedra, manufacturers substituted bitter orange in many herbal weight-loss products, despite similar concerns about potential serious side effects and lack of effectiveness. In a recent article by the publication Consumer Reports, it was furthermore reported that use of bitter orange may be associated with "fainting, heart-rhythm disorders, heart attack, stroke, [and] death".
