Ingredient notes

What to know about black seed

Black seed is Nigella sativa, the small matte-black seed scattered over naan and Turkish bread and stirred into Bengali panch phoron. As a spice it grades clean across the board here, with no histamine, no tyramine, no free glutamate, no sulfites, no salicylate flag and no FODMAP load. The reason it needs a page at all is that most people meeting it now are not meeting a spice. They are taking black seed oil capsules or a spoon of cold-pressed oil standardised for thymoquinone, and that is a daily dose orders of magnitude larger than anything you would sprinkle on bread. Almost every reported side effect and drug interaction belongs to the supplement, not the seed.

Watch for

  • The culinary dose and the supplement dose are not the same exposure.A pinch of seed on flatbread is a fraction of a gram, while black seed oil regimens run one to three grams a day standardised for thymoquinone, the compound that makes up roughly half a percent to two percent of the oil. If you started a supplement, log it as a supplement.
  • At supplement doses the common complaints are gastric: bloating, nausea, loose stools and reflux.These read exactly like a new food intolerance in a diary, so a black seed oil start date is worth marking before you go hunting through your meals.
  • Thymoquinone interacts with cytochrome P450 enzymes including CYP2C9, the pathway that clears warfarin, and trials consistently show modest blood-sugar and blood-pressure lowering.Stacked with an anticoagulant, a diabetes drug or a blood-pressure medication, the effects add up. Clear a black seed oil habit with whoever manages your prescriptions.
  • Rash and skin hypersensitivity are the recurring non-gut reports, and contact dermatitis from black seed oil applied to skin is documented.Nigella sativa is unrelated to true cumin despite the shared name, so a cumin allergy tells you nothing about it.
  • As a whole spice it grades clean on histamine, gluten, lactose, nickel, sulfites, nightshades and all FODMAP subgroups, which makes it one of the easier ways to add flavour on a restricted diet.
