Cinnamon Essential Oil

Cinnamon essential oil (Cinnamomum verum J.Presl, syn. C. zeylanicum) evokes warmth, comfort, and the festive season. This ancient spice, native to Sri Lanka, has been treasured for thousands of years — it was more valuable than gold in ancient Egypt and a driving force behind the spice trade that shaped world history. Two distinct oils are produced from the cinnamon tree: bark oil, dominated by cinnamaldehyde, and leaf oil, rich in eugenol. Both are remarkably powerful antimicrobials but require careful handling due to their potency.

Main Properties

Cinnamon’s potent properties come from cinnamaldehyde (bark) or eugenol (leaf):

• Powerful antimicrobial: One of the strongest antimicrobial essential oils, active against bacteria, fungi, and some viruses.
• Warming and circulatory: Stimulates blood flow and creates a sensation of warmth.
• Antispasmodic: Helps ease digestive cramps and bloating.
• Immunostimulant: Supports immune function during cold and flu season.
• Strong skin irritant: Must be used with extreme caution topically — maximum 0.5% dilution.

Benefits and Uses

For Diffusion and Air Purification

Cinnamon shines in the diffuser. Add 2-3 drops (no more) blended with gentler oils like sweet orange or mandarin for a warm, inviting atmosphere that also purifies the air.

For Immune Support

During cold and flu season, diffuse cinnamon with clove and citrus oils to support immune defenses. The antimicrobial vapors help reduce airborne pathogens.

For Warming Blends

Cinnamon is essential in winter and Christmas blends. Its warm, spicy character anchors festive diffuser recipes beautifully. Always blend with skin-safe oils if the blend will be used topically.
