Black cumin (Nigella sativa), known as "black seed," has been traditionally used in Middle Eastern and South Asian medicine for respiratory ailments, including colds. Modern scientific research has begun to explore its potential antiviral and immune-modulating properties. Several in vitro and animal studies have demonstrated that black cumin seed oil and its active constituent, thymoquinone, possess antiviral activity against a range of viruses, such as cytomegalovirus, hepatitis C, and influenza. For example, a 2013 study in "Archives of Virology" found that Nigella sativa seed extract significantly reduced influenza virus replication in cell cultures. Additionally, black cumin appears to enhance certain immune responses, such as increasing natural killer cell activity and modulating cytokine production, which could theoretically help the body combat viral infections like the common cold.

However, clinical evidence in humans is limited. Some small-scale trials have shown benefits for asthma and allergic rhinitis, but there are very few well-designed human studies specifically evaluating black cumin’s efficacy for the common cold or other viral respiratory infections. Thus, while promising laboratory results and traditional use suggest potential, the current scientific evidence is moderate and not yet sufficient for strong clinical recommendations. Further, larger human trials are necessary to confirm both safety and efficacy for this specific indication.
