Cassia (Cinnamomum cassia) is one of those oils that commands attention from the first drop — intensely spiced, warm, and woody. It earns its place across a wide range of applications, from the kitchen to the massage table, with a profile that is as broad as it is potent.

🌿 Cinnamaldehyde — a dominant, multi-target active. The cinnamaldehyde-dominant profile (80–95%) gives this oil its antibacterial, antifungal, antiviral, and anti-infectious character. It is one of the most studied aromatic compounds in the pharmacopoeia — broad-spectrum, grounded in literature, and consistently effective across skin, digestive, and immune applications.

💪 Circulatory and warming — felt immediately. Rubefacient and circulatory by nature, Cassia stimulates local blood flow on contact when properly diluted (max 5% in a carrier oil). It is traditionally used for cold extremities, muscle tension, and sluggish circulation. The warming effect is immediate; the action is documented.

⚡ Energizing and immunostimulant. Tonic and nerve-stimulating, Cassia is traditionally used to counter fatigue and support the immune system. It does not sedate — it activates. A reliable ally during seasonal changes and periods of low energy.

🍽️ A certified culinary oil — one drop is enough. Food-grade and intensely flavoured — a single drop, first diluted in a fatty or sweet carrier, is enough to define a recipe. It pairs naturally with baked goods, spiced drinks, chocolate preparations, and slow-cooked dishes. 100% pure, organic (FR-BIO-01), HEBBD/HECT, steam-distilled from Cinnamomum cassia twigs and leaves grown in Asia. Every batch chromatography-verified.

🌿 The Cinnamon Family — One Name, Many Oils

“Cinnamon essential oil” is not a single product. The genus Cinnamomum encompasses several species, each with a distinct chemical profile, scent, safety level, and therapeutic scope. The part of the plant distilled — bark or leaves/twigs — further changes everything. Knowing which cinnamon you are working with is not a detail — it is the whole point.

A note on “true” cinnamon: botanically, Cinnamomum verum (syn. Cinnamomum zeylanicum) is the “true” cinnamon — its species name verum means “true” in Latin. Native to Sri Lanka (formerly Ceylon), it is the cinnamon of historical spice trade. Cassia (Cinnamomum cassia) is widely sold as “cinnamon” in commerce — particularly in North America and Europe — but is a distinct species: more pungent, higher in cinnamaldehyde, and less nuanced. Both are valuable; neither is inferior — they simply serve different purposes.

🌟 Cassia — The Hero of This Product

Cinnamomum cassia (syn. Cinnamomum aromaticum) — also known as Chinese Cinnamon — is the most cinnamaldehyde-rich cinnamon species. Steam-distilled from twigs and leaves, its essential oil contains up to 88% trans-cinnamaldehyde, giving it an intense, warm, spiced, and sweet character that is both immediately recognisable and remarkably persistent. This profile makes it one of the most potent broad-spectrum protective oils in aromatherapy: powerfully antibacterial, antiviral, antifungal, anti-infectious, and immunostimulant, with documented circulatory, digestive, and blood sugar-regulating properties. It is also food-grade — a single drop transforms a recipe. Always dilute to a maximum of 5% in a carrier oil for topical use.

⚠️ Cassia is dermocaustic and skin-sensitizing. It is contraindicated during pregnancy and breastfeeding, and not recommended for children under 6. Diffusion is permitted with caution — maximum 10 minutes, adults only, forbidden around children under 12. Inhalation is not recommended.

🟡 Ceylon Cinnamon (Bark) — The Refined One

Cinnamomum verum (syn. Cinnamomum zeylanicum) bark oil is the most prized cinnamon in perfumery and aromatherapy. Rich in cinnamaldehyde (55–75%) but also eugenol and other minor compounds, it has a more complex, nuanced, and slightly floral scent compared to cassia. It is equally dermocaustic — strict dilution required (maximum 0.5–1% on skin). Highly valued for its anti-infectious, aphrodisiac, and digestive properties. More expensive and rarer than cassia.

🟢 Ceylon Cinnamon (Leaf) — The Safer Alternative

Cinnamomum verum leaf oil is dominated by eugenol (70–95%) rather than cinnamaldehyde. Its scent is spicy and clove-like, quite different from bark or cassia oils. It is less dermocaustic than bark oil and cassia, making it more accessible for topical use — though still requiring dilution. Antibacterial, antifungal, and analgesic. A more affordable and safer entry point into the cinnamon family for skin applications.

🔍 Choosing the Right Cinnamon — A Quick Reference

• Cassia / Chinese Cinnamon (Cinnamomum cassia, twigs & leaves) — Key molecule: Cinnamaldehyde < 88%. Character: intensely spiced, warm, sweet, woody. Best for: broad-spectrum protection, circulatory support, digestive & metabolic health, culinary use, skin & scalp care. Max 5% dilution. Not for children under 6, pregnancy, or breastfeeding.
• Ceylon Cinnamon Bark (Cinnamomum verum, bark) — Key molecules: Cinnamaldehyde, eugenol. Character: refined, complex, slightly floral-spiced. Best for: anti-infectious, aphrodisiac, digestive use. Max 0.5–1% on skin. Strict dilution required.
• Ceylon Cinnamon Leaf (Cinnamomum verum, leaf) — Key molecule: Eugenol 70–95%. Character: spicy, clove-like. Best for: antibacterial, antifungal, analgesic use. More tolerated on skin than bark or cassia. Still requires dilution.

⚠️ Always check the botanical name and the part of the plant (bark vs. leaf/twig) on the label before purchasing or using any cinnamon essential oil. The common name alone is not sufficient.

📜 Cassia in History & Culture

• Cassia (Cinnamomum cassia) is one of the oldest documented spices in human history. It appears in Chinese botanical records as early as 2700 BCE, cited in the Shennong Bencao Jing (Divine Farmer’s Classic of Materia Medica) — one of the foundational texts of traditional Chinese medicine — where it is described as warming, tonifying, and beneficial for the digestive and circulatory systems. It has been in continuous therapeutic use for nearly five millennia.
• In ancient Egypt, cassia was among the aromatics used in the embalming process and in kyphi — a sacred incense blend burned in temples. It was imported via the spice trade routes from Asia and was considered a luxury commodity of the highest order. The Greek historian Herodotus described the harvesting of cassia as a dangerous and mythologised affair, suggesting its rarity and value in the ancient Mediterranean world.
• Cassia is also referenced in the Hebrew Bible (Exodus 30:24) as one of the ingredients of the holy anointing oil — alongside myrrh, calamus, and cinnamon. The Hebrew term qetsiʿah is widely interpreted by scholars as referring to Cinnamomum cassia. Few plants carry this depth of cross-cultural sacred and medicinal history.

🌿 Botanical & Aromatherapy Notes

• In aromatherapy, Cinnamomum cassia occupies a position of exceptional potency. Franchomme & Pénoël (L’aromathérapie exactement, 1990) classify cinnamaldehyde-dominant oils among the most powerful anti-infectious agents in the aromatic pharmacopoeia, noting their broad-spectrum action across bacterial, viral, fungal, and parasitic pathologies. Baudoux highlights cassia’s tonic, immunostimulant, and aphrodisiac properties, placing it among the major warming and protective oils. Its potency demands respect: always diluted, always dosed with precision.
• The oil’s character is defined almost entirely by one molecule: trans-cinnamaldehyde (up to 88%). This aldehyde is responsible for the characteristic warm, spiced, sweet scent; the antibacterial, antiviral, and antifungal activity; the rubefacient and circulatory action; and the dermocaustic potential that makes dilution non-negotiable. Minor constituents — including cinnamyl acetate and coumarin — contribute to the oil’s complexity and its blood-thinning properties.
• It blends naturally with Ravintsara, Lemon, Orange, Clementine, Bergamot, Chamomile, Clove, and Mandarin. In blending, it plays a dominant, warming role — a little goes a long way. Even at low concentrations, cassia defines the character of a blend.

🧪 Scientific Fun Fact

Trans-cinnamaldehyde — the dominant molecule in cassia — has been the subject of extensive research into its anti-biofilm activity: its ability to disrupt and prevent the formation of bacterial biofilms, the protective structures that make certain bacteria highly resistant to conventional antibiotics. A 2004 study published in the Journal of Applied Microbiology demonstrated that sub-inhibitory concentrations of cinnamaldehyde — too low to kill bacteria outright — were sufficient to inhibit biofilm formation in E. coli and other pathogens. This means cassia doesn’t just fight bacteria — it disrupts their ability to organise and defend themselves. In an era of growing antibiotic resistance, this property has attracted serious scientific interest. Cassia is not a medicine — but the molecule at its core is one that modern pharmacology is paying close attention to.
