Known as the “Princess Flower,” bitter orange blossom earned its name from a 17th-century Italian princess who adored its scent and used it daily. As she graced social events with an elegant, noble aroma, people began to name this captivating white blossom “Neroli” in her honor. Although botanically similar to the edible and medicinally acclaimed Daidai Flower—both belonging to the citrus genus in the Rutaceae family—bitter orange blossom’s fragrance is notably more delicate and complex. With a mildly pungent, sweet, and slightly cool character, it enters the heart, liver, and spleen meridians and is valued for regulating Qi, alleviating depression, and promoting restful sleep. It is widely applied for skin brightening, deep hydration, and anti-aging as well as in aromatherapy to relieve tension and mood swings.
