Nigellin® Black Seed Oil Extract Description
Nigella sativa (also known as Black Caraway Seed, Black Seed Oil, and Kalonji) is a prized flowering plant which produces black seeds containing a powerful bioactive molecule called thymoquinone (1).
The Nigella sativa plant is part of the Ranunculaceae family which is native to southwest Asia and has been grown and cultivated in North Africa and Europe for over 2000 years (2)(4).
Its seeds contain a variety of constituents and fatty acids, but its’ thymoquinone has been isolated as its primary bioactive ingredient. The black seeds of the N. sativa plant have been used as a pungent spice and condiment, and the oil pressed from the seeds has been used as a folkloric remedy or as cosmetic oil for the skin and hair (2)(1).
It is known by many names depending on its cultural location; for instance, it is known as black cumin in English-speaking countries even though black cumin comes from another plant (B. bulbocastanum) (3).
Thymoquinone is found in the essential oil portion of the N. sativa seed. The remainder of the seeds are proteins, saponins, and alkaloids (2).
Since the thymoquinone concentration is the most important bioactive constituent, it is the ingredient to which N. sativa seed extracts are standardized. The two most common extraction methods are to cold press the oil or to use a chemical solvent like hexane or methanol. A third option for extraction has been proven to provide the highest amount of thymoquinone and antioxidants and is the preferred industry method for extraction of the active properties of the seed. This method is called supercritical fluid extraction; and because it uses liquid carbon dioxide to extract the phenolic compounds from the crushed seeds, it provides a higher yield of active ingredients and is the most environmentally friendly choice (6).
Pure Nootropics chooses to use this superior form of black seed oil extract which has been expertly formulated by the Sabinsa company in their trademarked product Nigellin® (7).
