What is Black Seed Oil?

Black seed oil is pressed from the seeds of Nigella sativa, a plant used across Middle Eastern and South Asian traditions for centuries. Its signature compound, thymoquinone, drives antioxidant and immune-modulating activity in laboratory and human studies. Small clinical trials point to modest support for healthy blood pressure, blood sugar, cholesterol, and inflammatory markers, though the studies are short and varied, so it is best seen as a gentle general-wellness oil rather than a targeted treatment. Quality depends on thymoquinone content and cold pressing. It can mildly lower blood pressure and blood sugar and has mild blood-thinning activity, so use caution alongside related medications and in pregnancy. Around 500 to 1000 mg of oil, or a teaspoon, daily is typical.
