Abstract
Clove (Syzygium aromaticum), an aromatic spice known for its therapeutic and culinary value, has emerged as a significant subject of scientific inquiry due to its broad range of bioactive compounds and diverse industrial applications. This review provides a comprehensive overview of the chemical composition of clove essential oil (CEO), its biological activities, and its utilization across multiple industries. The chemical profile of CEO is dominated by eugenol, along with other important constituents such as Eugenol, β-caryophyllene, eugenyl acetate, and α-humulene, which collectively contribute to its pharmacological efficacy. Clove exhibits a variety of biological activities, including strong antioxidant potential, which helps in combating oxidative stress; notable antimicrobial effects against bacteria, fungi, and viruses; anti-inflammatory activity through inhibition of pro-inflammatory mediators; cytotoxic effects with promising anticancer properties; and anti-hypertensive action, likely mediated through vascular relaxation and calcium channel modulation. In addition to its therapeutic value, clove finds widespread application in the food, pharmaceutical, cosmetic, agricultural, and tobacco industries due to its preservative, flavouring, medicinal, and aromatic properties.
This review reveals that Clove, and its essential oil serve as natural, and multifunctional resource with significant potential for further development in both therapeutic and industrial sectors.
