Varieties

★ ''Citrus aurantium'' subsp. ''amara'' is a spiny evergreen tree native to southern Vietnam, but widely cultivated. It is used as grafting stock for citrus trees, in marmalade, and in the liqueurs Triple sec, Grand Marnier and Curaçao. It is also cultivated for the essential oil expressed from the fruit, and for neroli oil and orange flower water, which are distilled from the flowers.

★ 'Seville orange' (or ''bigarade'') is a widely-known, extremely tart orange now grown throughout the Mediterranean region. It has a thick, dimpled skin and is prized for making marmalade, being higher in pectin than the sweet orange, and therefore giving a better set and a higher yield. It is also used in compotes and for orange-flavored liqueurs.

★ Bergamot orange, ''C. aurantium'' subsp. ''bergamia'' is cultivated in Italy for the production of bergamot oil, a component of many brands of perfume and tea.

★ Chinotto, from the myrtle-leaved orange tree, ''C. aurantium'' var. ''myrtifolia'', native to Italy

★ Daidai, ''C. aurantium'' var. ''daidai'', used in Chinese medicine and Japanese New Year celebrations.

Uses in Cooking

The unripe fruit called "narthangai" is commonly used in Southern Indian food, especially in Tamil cuisine. The unripe fruit is pickled by cutting it into spirals and stuffing it with salt. The pickle is usually consumed with thayir sadam. The fresh fruit is also used frequently in pachadis.
The juice from the ripe fruit is also used as a marinade in meat in Cuban cooking.
The peel can also become an ingredient in bitters.

Health supplement status

The extract of bitter orange (and bitter orange peel) has been used in dietary supplements as an aid to fat loss and as an appetite suppressant, although in traditional Chinese medicine, it is always prescribed in concert with other support herbs, not in isolation. Bitter orange contains synephrine, a drug similar to ephedrine, acting as a stimulant (β₃ agonist) with a possible risk of ischemic stroke and heart problems.
