AL BAARii Pure Kalonji oil is the cold-pressed fixed oil from the seeds of Nigella sativa, a flowering plant in the buttercup family (Ranunculaceae). You may also see it sold as black seed oil or black cumin seed oil (not to be confused with culinary cumin). The oil contains a mix of fatty acids—mainly linoleic (omega-6), oleic (omega-9), and smaller amounts of palmitic—plus volatile constituents such as thymoquinone (TQ), dithymoquinone, thymohydroquinone, and p-cymene. Thymoquinone is often considered the signature molecule tied to the oil’s antioxidant and anti-inflammatory effects.
