The genus Nigella (Ranunculaceae) is distributed throughout the Mediterranean basin. Badalamenti et al. (2022) have published a systematic review on the medicinal and traditional use, chemical composition, toxicology and phytotherapy of Nigella damascena L., also known as “love-in-a-mist” and “devil in a bush”. This beautiful plant is It is native to southern Europe, north Africa and southwest Asia, where it is found on neglected, damp patches of land.
From the abstract (with some slight changes in wording):
Nigella damanscena L. is traditionally used as an ingredient in food, for example, as flavouring agents in bread and cheese, but is also known in folk medicine, used to regulate menstruation; for catarrhal affections and amenorrhea; as a diuretic and sternutatory; as an analgesic, anti-oedematous, and antipyretic; as a disinfectant and vermifuge. This paper reviews the most dated to the latest scientific research on this species, highlighting the single isolated metabolites and exploring their biological activity.
Fifty-seven natural compounds have been isolated and characterised from the seeds, roots, and aerial parts of the plant. Among these constituents, alkaloids, flavonoids, diterpenes, triterpenes, and aromatic compounds are the main constituents. The isolated compounds and the various extracts obtained with solvents of different polarities presented a diverse spectrum of biological activities such as antibacterial, antifungal, antitumour, antioxidant, anti-inflammatory, antipyretic, anti-oedema, and antiviral activities. Various in vitro and in vivo tests have demonstrated the pharmacological potential of β-elemene and the alkaloid damascenin. Unfortunately, the largest number of biological studies on this species and its metabolites have been conducted in vitro. Further investigation is necessary to evaluate the toxicological aspects, mechanisms of action and real therapeutic potential of extracts of N. damascena.
