Black seed oil and inflammation: what thymoquinone research shows

By Chidi Nneji, MPharm · Updated 16 October 2026 · Editorial standards

Thymoquinone is a constituent of Nigella sativa (black seed). Researchers have studied how it interacts with inflammatory and oxidative signalling, including NF-κB, largely in laboratory and animal work. Those mechanisms cannot establish that black seed oil treats chronic inflammation, improves immunity or addresses a person's symptoms.

What about trials in people?

Some small trials of black seed preparations have reported changes in markers such as glucose, lipids or C-reactive protein. Preparations, doses, populations and study quality vary. A change in a blood marker is not proof that a supplement prevents disease or that one ingredient works the same way in another formula. The evidence does not justify treating high CRP or persistent symptoms with black seed oil instead of obtaining an assessment.

Safety and context

Symptoms such as fatigue, joint pain or high blood sugar have many possible causes. Seek medical advice for persistent symptoms and continue prescribed treatment. Discuss a black seed product with a pharmacist if you take medicines or are pregnant or breastfeeding. The specific preparation and its quality information matter.
