Nigella is a genus of about 25 species of annual or biennial plants in the family Ranunculaceae, native to Macaronesia, southern and central Europe, North Africa, the Middle East, and Central Asia. [1] [2] Common names applied to members of this genus are nigella, devil-in-a-bush or love-in-a-mist.
The species grow to 20 to 90 cm (8 to 35 in) tall, with finely divided leaves; the leaf segments are narrowly linear to threadlike. The flowers are white, yellow, pink, pale blue or pale purple, with five to ten petals. The fruit is a capsule composed of several united follicles, each containing numerous seeds; in some species (e.g. Nigella damascena ), the capsule is large and inflated.
The seeds of Nigella sativa , known as kalonji, black cumin, black caraway, black coriander, roman coriander, black onion seed, onion seed, charnushka, git (in historical Roman cuisine), [3] or just nigella, are used as a spice and a condiment in South Asian, Ethiopian, Middle Eastern and Polish cuisines. [4]
Several species are grown as ornamental plants in gardens. Nigella damascena has been grown in English cottage gardens since the Elizabethan era, commonly called love-in-a-mist. Nigella hispanica is a taller species with larger blue flowers, red stamens, and grey leaves. Nigella seeds are self-sowing if the seed pods are left to mature.
The dried seed capsules can also be used in flower arrangements.
In traditional medicine, the seeds are used as a carminative and stimulant to ease bowel and indigestion problems, and are given to treat intestinal worms, nerve defects, to reduce flatulence, and induce sweating. Dried pods are sniffed to restore a lost sense of smell. It is also used to repel some insects, much like mothballs.
Numerous studies have shown that it has anti-inflammatory, [5] anti-oxidative, [6] anti-mycotic, antibacterial, [7] [8] [9] anti-fungal, anti-cancer, [10] [11] [12] [13] [14] anti-viral, antihistamine properties, possessing many properties that make it a potential remedy against certain diseases. [15]
Black cumin is used by naturopaths. Black cumin oil and powder are sold to people suffering from pathologies such as skin diseases, muscle pain, eczema or psoriasis, [16] but also acne, [17] diabetes, and asthma, [18]
