Essential Oil - Cinnamon
Essential Oil – Cinnamon
Botanical Information
Cinnamon (Cinnamomum zeylanicum), now more commonly classified as Cinnamomum verum, belongs to the Lauraceae family. It is also known as Ceylon Cinnamon, True Cinnamon, Seychelles Cinnamon, and Madagascar Cinnamon. This tropical evergreen tree can grow up to 15 metres tall and features sturdy branches, rough aromatic bark, glossy leathery leaves, small white flowers, and bluish-white berries. When crushed, the leaves release a warm, spicy fragrance that is characteristic of cinnamon.
Habitat and Cultivation
Cinnamon is native to Sri Lanka, Madagascar, the Comoro Islands, Southern India, Myanmar (Burma), and Indochina. It is also cultivated commercially in India, Jamaica, and several African countries. Different growing regions produce distinct varieties, each with subtle differences in aroma and chemical composition. The finest quality cinnamon is traditionally associated with Ceylon (Sri Lanka).
Related Species
Several closely related species are also cultivated for spice and essential oil production, including Saigon Cinnamon (Cinnamomum loureiroi) and Batavia Cinnamon (Cinnamomum burmannii). While these varieties are widely used, Ceylon Cinnamon (C. verum) is generally regarded as the premium species because of its milder flavor and more refined aromatic profile.
Traditional Uses
For thousands of years, cinnamon has been one of the world’s most valued culinary and medicinal spices. The inner bark is harvested every two years, dried into the familiar cinnamon sticks, and used extensively in cooking and herbal medicine. Traditional healers throughout Asia prescribed cinnamon to relieve colds, influenza, digestive disorders, menstrual discomfort, rheumatism, and kidney ailments, while also using it as a general warming and stimulating tonic. It remains recognized in the British Herbal Pharmacopoeia as a traditional remedy for flatulent colic, indigestion, and nausea.
Therapeutic Actions
Cinnamon essential oil is traditionally regarded as anthelmintic, antidiarrheal, antimicrobial, antiseptic, antispasmodic, aphrodisiac, astringent, carminative, digestive stimulant, emmenagogue, hemostatic, circulatory stimulant, cardiac stimulant, respiratory stimulant, stomachic, vermifuge, and antiparasitic. Its warming nature has made it a valued oil for supporting digestion, circulation, and immune health.
Extraction Method
Two distinct essential oils are produced from the cinnamon tree. Leaf oil is extracted through steam or water distillation of the leaves and young twigs, while bark oil is obtained by distilling the dried inner bark. These oils differ significantly in both aroma and chemical composition.
Aroma and Characteristics
Cinnamon Leaf Oil is a yellow to brownish liquid with a warm, spicy, slightly harsh aroma. Cinnamon Bark Oil ranges from pale yellow to deep amber and possesses a richer, sweeter, warm, spicy fragrance with a dry, persistent character. Cinnamon blends exceptionally well with frankincense, ylang-ylang, orange, mandarin, benzoin, Peru balsam, and other oriental fragrance notes.
Major Chemical Constituents
Cinnamon Leaf Oil contains predominantly eugenol (approximately 80–96%), together with eugenol acetate, cinnamaldehyde, benzyl benzoate, linalool, and safrole. Bark Oil is rich in cinnamaldehyde (approximately 40–50%) along with eugenol, benzaldehyde, cuminaldehyde, pinene, cineole, phellandrene, furfural, cymene, and linalool.
Safety Profile
The two oils have very different safety profiles. Cinnamon Leaf Oil is considered relatively safe when properly diluted, although its high eugenol content may irritate the skin and mucous membranes if overused. Cinnamon Bark Oil is significantly more hazardous and is regarded as a strong skin irritant, sensitizer, and dermal toxin. It should never be applied directly to the skin and should only be used under professional guidance. Both oils should be avoided during pregnancy unless advised by a qualified healthcare practitioner.
Aromatherapy Uses
In aromatherapy, Cinnamon Leaf Oil is used to support poor circulation, rheumatism, digestive sluggishness, indigestion, colitis, diarrhea, and intestinal infections. It is also traditionally applied for head lice, scabies, warts, tooth and gum care, and wasp stings. Its warming, stimulating properties make it popular for easing fatigue, nervous exhaustion, stress, colds, influenza, and other seasonal illnesses. Historically, it has also been used to stimulate uterine contractions during childbirth and to support certain women’s health conditions, although these uses require professional supervision.
Other Uses
Both Cinnamon Bark Oil and Cinnamon Leaf Oil are widely used in the pharmaceutical, food, and fragrance industries. They are common ingredients in toothpastes, mouthwashes, nasal sprays, cough syrups, and dental preparations because of their antimicrobial properties. Cinnamon Leaf Oil is also incorporated into soaps, cosmetics, toiletries, and perfumes, while both oils are extensively used to flavor foods, confectionery, alcoholic beverages, and soft drinks, including well-known cola beverages.
