Rating (out of 5): 2

Black cumin (Nigella sativa) has a long history of use in traditional medicine systems, particularly in the Middle East, South Asia, and parts of Africa, for the management of colds and feverish illnesses. Historical texts and ethnobotanical surveys document its use as a remedy to alleviate symptoms of the common cold, such as fever, congestion, and cough. The seeds are typically consumed whole, ground, or as an oil, and sometimes incorporated into warm teas or decoctions. The traditional rationale is based on black cumin’s perceived “warming” properties and its role in boosting the body’s natural defenses.

Modern scientific studies have identified various bioactive compounds in black cumin, notably thymoquinone, which exhibit immunomodulatory, anti-inflammatory, and mild antipyretic (fever-reducing) properties in animal and in vitro studies. Some small clinical trials and observational studies suggest a potential for black cumin to modestly reduce the severity or duration of cold symptoms, but these findings are preliminary and not robust enough to constitute strong scientific validation. Overall, while scientific interest exists, the use of black cumin for colds with fever is primarily justified by tradition, with only limited and low-quality scientific evidence to support its effectiveness for this condition.
