BLACK CUMIN / NIGELLA
Nigella Sativa
Nigella belongs to the Order Ranunculaceae and is an annual herb, 8 to 12 inches high, with leaves cut into numerous, narrow, pinnate segments. The flowers are solitary, terminal, without an involucre; the petals blue and white, with greenish glands. The capsule is formed of 3 to 6 carpels, opening by the ventral suture. .
Properties
The seeds contain the components Nigellone und Thymoquinone. Nigellone is a polymer of the Thymoquinone which inhibit the cyclo-oxygenase and the lipoxygenase pathway of the arachidonic metabolism. Lipoxygenase catalyses the formation of leukotrienes from arachidonic acid which function as a mediator of allergies and inflammations. First step of the reaction is a - enzymatically formed - peroxide. Cyclo-oxygenase is the initial enzyme of the cyclooxygenase metabolism which yields from arachidonic acid eventually prostaglandines (and thromboxane). Prostaglandines are also mediators of inflammations.
Also non-enzymatic peroxidation was found to be inhibited. This inhibitory effect of Nigella fixed oil can only partly be explained by the presence of Thymoquinone. A substrate inhibition by uncommon C20:2 unsaturated fatty acids (which are similar to arachidonic acid) may also play a role. The research results support the traditional use of Nigella oil against rheumatical and inflammatory diseases. (see bibliography)
