Black seed oil, also called Nigella sativa, black cumin seeds, or kalonji, has been valued for over 2,000 years in traditional cultures. Known in Arabic history as the "Blessed Seed," it has been used in the Middle East, Africa, and South Asia as part of natural health practices. Today, researchers continue to study black seed oil supplements for their unique plant compounds and possible role in supporting the body.
The Many Names of Black Seed Oil
- Nigella sativa – the scientific name
- Black cumin seeds – common in South Asia
- Kalonji – widely used in India
- Blessed seed – a traditional Arabic name
History and Traditional Use
For centuries, black seed oil has been a staple in traditional medicine systems. Ancient texts reference its use in cooking, topical applications, and herbal mixtures. People have valued it for supporting skin comfort, digestion, and general vitality. While ancient cultures used the seeds, oil, and extracts in many ways, modern science is exploring the compounds inside that make Nigella sativa unique.
The Science Behind Black Seed Oil: Thymoquinone
The most studied compound in black seed oil is thymoquinone. Research shows that thymoquinone makes up about 30–48% of the essential oil and has antioxidant properties that may help protect cells from oxidative stress (Ahmad et al., 2013). Scientists are exploring how thymoquinone interacts with the immune system, metabolism, and skin health.
Black Seed Oil Benefits
While research is ongoing, here are several areas where black cumin seeds and black seed oil supplements have been traditionally used and scientifically studied for their potential support:
1. Supports Metabolic Health*
Studies suggest that Nigella sativa may help maintain normal blood sugar and cholesterol levels already within a healthy range (Heshmati et al., 2015). This makes it a popular choice for people looking to support everyday metabolic balance.
2. Supports Kidney Function*
Traditional uses of black cumin seeds include supporting urinary and kidney health. Some studies suggest extracts may help protect kidney cells from stress, though more research is needed (Kanter, 2008).
3. Skin and Scalp Support*
Black seed oil is often applied topically to help soothe the skin. Research has explored its role in calming occasional irritation, reducing dryness, and supporting skin barrier function (Aljabre et al., 2015). Many people also use it for scalp comfort and to support strong, healthy-looking hair.
4. Immune System Support*
Modern studies suggest that compounds in black seed oil may influence immune function. Research shows that extracts can help modulate natural defense cells, supporting a balanced immune response (Gholamnezhad et al., 2016).

In traditional practices, black cumin seeds were consumed to support digestive comfort. They are rich in fiber and plant compounds that may help maintain gut health.
