Antioxidant Properties and Therapeutic Use of Cinnamon

Cinnamon (Cinnamomum spp.) is an aromatic spice widely recognised for its culinary, nutritional, and medicinal significance.

It contains a wide range of bioactive compounds that exhibit antioxidant, anti-inflammatory, antimicrobial, and antidiabetic activities. This research paper systematically reviews the antioxidant properties and therapeutic potentials of cinnamon, highlighting its phytochemical composition, mechanisms of antioxidant action, and clinical relevance in managing oxidative stress-related diseases. Data were synthesised from major databases published between 2000 and 2024. Findings show that cinnamon possesses strong radical scavenging capacity, promotes endogenous antioxidant defence, and shows therapeutic potential against diabetes, cardiovascular, neurodegenerative, and infectious diseases. However, variations in species, dosage, and preparation methods influence results. Further standardised clinical studies are essential to confirm its long-term safety and efficacy.
