From the Research

Black seed oil, derived from Nigella sativa, offers several health benefits but requires careful use, as evidenced by its anti-inflammatory, immunomodulatory, and antioxidant properties 1. It may help reduce inflammation, support immune function, improve digestive health, and potentially assist with blood sugar and cholesterol management when taken in doses of 1-2 teaspoons daily. Some people apply it topically for skin conditions or hair health. However, several precautions are necessary: pregnant women should avoid it due to potential uterine stimulation; it may interact with medications, particularly blood thinners and diabetes medications; and it can cause digestive upset, allergic reactions, or liver problems in some individuals. Start with a small dose (1/4 teaspoon) to test tolerance, and discontinue use if adverse reactions occur. The oil's benefits stem from thymoquinone, a compound with antioxidant and anti-inflammatory properties that helps neutralize free radicals and reduce inflammatory markers in the body, as shown in a study on its effects on inflammatory and immunomodulatory markers in Plasmodium berghei-infected mice 1. Always purchase cold-pressed, high-quality oil and store it in a cool, dark place to maintain potency.
