Seeds of the plant Nigella sativa (and the extracted oil, called “black seed oil”) are widely used in traditional medicine. Benefits attributed to this ingredient include antioxidant, immunomodulatory, anti-inflammatory, antihistaminic, antiallergic, antitussive and bronchodilatory properties. Many components of black seed oil have been identified and isolated, including components that may promote liver health, treat infection, aid digestion and provide other important health benefits. Constituents of black seed oil work to create balance in the immune system, reducing stress and promoting wellness.
