Clove (Syzygium aromaticum): Nature’s Tiny Powerhouse

Medicinal plants have gained significant attention because of their health-promoting properties, affordability, accessibility, and few side effects. Among different herbs that have been studied for the preparation of several traditional remedies since antiquity, clove (Syzygium aromaticum) has taken centre stage. Clove is a valuable and unusual spice from all over the globe. Clove is a substantial source of phenolic substances found in plants, including flavonoids, hydroxyl benzoic acids, hydroxyl cinnamic acids, and hydroxyl phenylpropenes. Eugenol is the principal bioactive ingredient found in clove. In addition, clove contains the phenolic acids ferulic, caffeic, elagic, and salicylic. Up to 18% of the essential oils found in cloves are found in the flower buds. The clove essential oil has been found to have a broad-spectrum pathogen-inhibitory effect. The -OH groups at the ortho and meta locations in the chemical structure of clove oil interact with the cytoplasmic membranes of microorganisms. Anti-oxidants included in clove oil, including eugenol, caryophyllene, eugenyl acetate, and humulene, help to protect cells from the harm caused by free radical oxidation. Clove oil has antiviral action against the HSV 1 and 2 and is also used to reduce the inflammation of the pharynx. It also has analgesic, antinociceptive, and anticancer properties. Clove has been used for a variety of therapeutic purposes, including antioxidant activity, antifungal, antiviral, antibacterial, anti-inflammatory activity, antithrombic activity, antipyretic and analgesic, anticonvulsant effect, antimycotic activity, insecticidal, antimutagenic effect, and antiulcerogenic activity.
