Bitter orange: nutrition facts and health benefits

Bitter orange

The bitter orange, also called bigarade orange coming from the orange tree, is a citrus fruit smaller than the sweet orange. Its orange skin is rough, thick and tinted with green. Its flesh is a little juicy, acidic and contains a lot of seeds. It is grown in Spain (Seville) as well as in regions with a warm climate.

History of the bitter orange

The orange originates from Southeast Asia. The Arabs would have introduced it in the 9th or 10th century in Persia, Iraq, Syria, Palestine, Egypt, North Africa, then in Sicily, Sardinia and Spain. It’s the Crusaders who diffused it throughout Europe where, for nearly 500 years, it was the only type of orange tree to be cultivated. At that time, it was mainly appreciated for its medicinal properties, for the bark entrusted with its fruits and for the fragrance that one draws from its flowers. In the 12th century, it was well settled in Seville (hence one of the vernacular names of its fruit “Seville orange”). Christopher Columbus introduced it to the Antilles on his second trip, and he reached the shores of mainland America around 1518. In the United States, where it found a particularly fertile land, bitter orange grew into vast wilderness gardens. It is said that it was the Amerindians who, by throwing the seeds of the fruits they had been given, contributed to the appearance of these orchards.

Without the commercial importance of the orange tree, bitter orange tree is now cultivated in many parts of the world. In China and Japan, people appreciate the flowers that are dried and added to the tea leaves. People also draw flowers from the essence of Neroli, which is used in perfumery (much more aromatic than which one draws from the flowers of the sweet orange) as well as in liqueurs, soft drinks, ice creams, pastries and chewing gum. The residue of the distilling is the so-called “orange blossom water”, which is often used in Oriental cuisine. From the bark of the immature fruit, another essence is used to aromatize liqueurs, including Grand Marnier, Cointreau and Curaçao. From the leaves and twigs removed during the pruning of the trees, people produce the small grain essence used in pharmacy, perfumery and in the food industry.

Almost all classes of medications are likely to interact with grapefruit and bitter orange: medicines for the treatment of cancer, depression, hypercholesterolemia, high blood pressure, cardiac problems, and others.

The consumption of as little as 250 ml of juice can cause an increase in the drug in the blood, which may persist for 3 days or more.

Health authorities are reminding to refrain from consuming these fruits or their juices unless you have consulted a doctor or pharmacist about the risk of adverse reactions.
