## Abstract

Antibiotic resistance is a significant global health challenge that demands innovative strategies to combat resistant pathogens. Spices, known for their culinary and medicinal qualities, have emerged as promising sources of antimicrobial agents due to their rich content of potent bioactive phytochemicals. Compounds such as flavonoids, phenolics, alkaloids, and terpenoids exhibit strong antibacterial, antifungal, and antiviral activities. These phytochemicals target microbial cell walls, membranes, and metabolic processes, effectively inhibiting pathogen growth and survival. Additionally, their ability to disrupt biofilms and synergize with conventional antibiotics enhances their potential to counter resistance mechanisms. This review examines the mechanisms and dissemination of antimicrobial resistance, the antimicrobial properties of spices and their phytochemicals, focusing on their modes of action, efficacy against multidrug‐resistant pathogens, specific extraction methods for each phytochemical, synergism with traditional antibiotics, safety and toxicological concerns, future research directions, and challenges in the widespread use of these spice‐derived compounds. It highlights the vast array of antimicrobial solutions derived from these spices and their natural phytochemicals, offering sustainable and effective means to address the escalating threat of antibiotic resistance.

This graphical abstract shows the antibacterial potential of phytochemicals from 15 spices, showcasing key compounds, their extraction methods, and mechanisms of action. It highlights membrane disruption, ROS generation, enzyme inhibition, and biofilm prevention as core antibacterial pathways.
