Roll Call does not check drug interactions or assess personal safety.
Black seed oil is pressed from the seeds of Nigella sativa, a flowering plant traditionally used in Middle Eastern and South Asian cooking and folk medicine. Its main studied constituent is thymoquinone.
Why it’s used
Taken to support general metabolic health, including blood sugar and cholesterol markers, and sometimes for its anti-inflammatory reputation.
What the evidence says
There is no NIH ODS fact sheet for black seed oil. A number of small human trials and systematic reviews report modest improvements in blood sugar or lipid markers, but studies are generally small, short, and of variable quality, and thymoquinone content is not standardized across products.
Context
Trials have used a range of oil or seed powder doses over weeks to a few months, with inconsistent standardization of active compound content, making it difficult to compare results or identify an effective amount.
