Cumin (Black Cumin / Kalonji) for Antioxidant Support

Research suggests that black cumin (Nigella sativa) may offer some antioxidant-related clinical benefits, based on limited available evidence. The single study in this set is a randomized, placebo-controlled trial examining a combination of honey and Nigella sativa in COVID-19 patients, which reported faster symptom resolution, improved viral clearance, and reduced mortality compared to placebo — outcomes that may partly reflect the antioxidant and anti-inflammatory properties attributed to the plant. However, because the intervention combined Nigella sativa with honey, it is not possible to attribute any observed effects to either ingredient alone, and the findings have not yet been independently replicated. Overall, the evidence base here is too narrow to draw firm conclusions about Nigella sativa specifically as an antioxidant supplement, and further studies isolating its effects would be needed to better evaluate this application.
