Detailed description
The bitter orange tree, Citrus aurantium, a member of the Rutaceae family, is widely cultivated in Mediterranean and subtropical regions. Its fruit, known as bigarade, is prized for its wealth of functional compounds, which complement a varied, balanced diet.
Bitter orange fruit is a natural source of flavonoids (hesperidin, naringin), limonoids and essential oils (limonene, β-myrcene). These compounds help protect cells against oxidative stress and support natural metabolic regulation mechanisms.
Traditionally, bigarade has been used to support digestive comfort and natural elimination mechanisms. Modern studies highlight its role in balancing the nervous system, improving appetite and soothing the respiratory tract.
