Black seed oil, also called black cumin oil, has been used for millennia for its multiple health benefits. The oil is extracted from the seeds by cold pressing. These seeds, which strongly resemble those of the poppy, are located in the fruit capsules of the plant and are extremely rich in vitamins, amino acids, polyunsaturated fatty acids, minerals, and essential oils.

Used for millennia in India, Egypt, and the Middle East as a spice but also in herbal medicine and aromatherapy, black seed oil only started to make its mark on western medicine in the last century. Indeed, since the beginning of the 1960s, black seed oil has been the subject of more than 450 studies.

Active substances in black seed oil

Like all oils, black seed oil contains 100% fat. The fatty acids and fat-soluble vitamins it contains may vary depending on its quality, so it is strongly recommended to favor quality oils, obtained by first cold pressing and preferably of organic origin.

The fatty acids in black seed oil are distributed as follows:

  • Monounsaturated fatty acids: 18 to 29% (oleic acid Omega 9)
  • Polyunsaturated fatty acids: 50 to 60% (Omega 3 linoleic acid)
  • Saturated fatty acids: 13-19% (mainly palmitic and stearic acid)

Black seed oil is also rich in vitamins A (as carotene), vitamin E, and B vitamins. It contains many active ingredients as well such as thymoquinone and para-cymene, nigelline, and nigellone.
