Antibacterial Activity of Nigella Sativa

Nigella sativa, commonly known as black seed or kalonji, is a widely used medicinal plant with a long history in traditional healthcare systems. Recent studies have confirmed its significant antimicrobial properties, particularly against multidrug-resistant bacteria, fungi, and viruses. The antimicrobial activity is largely attributed to its bioactive components, such as thymoquinone, which disrupt microbial membranes, inhibit enzyme activity, and generate reactive oxygen species. In vitro experiments have demonstrated the effectiveness of various seed extracts against both Gram-positive and Gram-negative bacteria, as well as clinical fungal and viral strains. These findings support the growing interest in N. sativa as a promising candidate for the development of novel antimicrobial drugs. Future research focusing on mechanisms of action, nano-delivery systems, and clinical trials could help transition this traditional remedy into modern therapeutics.
