Key Constituents

Cinnamaldehyde[2, 6, 7]

Trans-cinnamaldehyde is the principal constituent of cinnamon bark essential oil and the main driver of its antimicrobial, antifungal (anti-Candida) and anti-inflammatory activity, acting partly by damaging microbial cell membranes and inhibiting NF-kB signalling.

Essential (volatile) oil
Coumarin (species caution)[6]

Cassia cinnamon (C. cassia) contains high levels of coumarin, which is potentially hepatotoxic in excess; true Ceylon cinnamon (C. verum) contains only trace coumarin and is the safer culinary/medicinal choice. Several pooled clinical and antimicrobial studies do not distinguish the two species.

Coumarins
Thymoquinone[3, 9]

The principal bioactive constituent of the seed oil, responsible for much of its anti-inflammatory, antioxidant and antimicrobial activity.

Volatile oil (nigellone, thymol, carvacrol)[3]

The aromatic fraction of the seed, contributing antimicrobial and antioxidant activity.

Essential (volatile) oilThymolCarvacrol
Fixed oil (linoleic acid, oleic acid)[1]

The bulk lipid fraction of the seed (roughly a third of seed weight by weight), the carrier for the fat-soluble thymoquinone.

Alkaloids (nigellicine, nigellidine)[1]

Minor isoquinoline-type alkaloids studied for antioxidant activity.

Alkaloids
Saponins (alpha-hederin)[1]

Triterpene saponin studied for anticancer and antiparasitic activity.

Safety, Cautions & Contraindications

Safety note[8, 11, 12]Serious

True cinnamon (C. verum) is safe in culinary and moderate medicinal doses. Cassia (C. cassia) contains high coumarin — excessive intake may be hepatotoxic and should not be confused with true cinnamon. May lower blood sugar — use caution with antidiabetic medications. Avoid high doses during pregnancy.

Safety note[8, 11, 12, 16]Serious

Duke (2002) rates Ceylon cinnamon as +++ and provides clinical evidence (score 2) for antibacterial activity, consistent with Commission E and WHO recognition. Key activities include antifungal (anti-Candida), antispasmodic, and carminative effects. Cinnamon contains cinnamaldehyde, eugenol, and coumarin. Important safety concern: Duke's entry aggregates true cinnamon (C. verum) and cassia (C. cassia) — cassia contains significantly higher coumarin levels (potentially hepatotoxic) than true Ceylon cinnamon. True cinnamon (C. verum) has very low coumarin content and is safe at normal culinary doses. Medicinal dose: 0.5–1 g bark powder three times daily. Caution: cinnamon bark oil is highly irritating to mucous membranes (Duke, 2002).

Safety note[12, 13, 14, 15, 16, 17, 18]Caution

Generally well-tolerated in clinical trials at doses up to 200 mg/day of oil for 90 days. Potential side effects may include mild gastrointestinal discomfort. Contraindicated during pregnancy due to potential uterine stimulant effects. May interact with immunosuppressants and antidiabetic medications. Allergic reactions possible in sensitive individuals. Consult healthcare provider before use, especially with concurrent medications.

Safety note[12, 13, 14, 15, 16, 17, 18, 19]Caution

Duke (2002) describes black cumin (Nigella sativa) as one of the most multi-active medicinal spices, with experimental evidence for bronchodilation, immunostimulation, hepatoprotection, and antihistaminic activity. The prophet Muhammad reportedly described it as 'a cure for all things except death.' Key bioactive compounds include thymoquinone and nigellone. Antihistaminic and bronchodilatory activity supports its traditional use in asthma and allergic conditions. Duke notes it is generally safe at culinary amounts but recommends caution with medicinal doses in pregnancy due to potential uterotonic effects (Duke, 2002).

Botanical Description

Evergreen tree with smooth, thin, light brown bark and leathery, oval leaves with three prominent longitudinal veins, often flushed reddish-pink when young. Small, pale yellow-green flowers are borne in panicles, followed by small, dark, single-seeded berries. The thin inner bark is peeled and dried into the characteristic pale, tightly layered, multi-ply quills of true cinnamon.

Height: Up to 10-15 m (often coppiced lower in cultivation)
Habit: Evergreen tree, often coppiced/pruned under cultivation
Leaves: Leathery, oval, three prominent longitudinal veins, reddish-pink when young
Flowers: Small, pale yellow-green, in panicles
Stem: Smooth, thin, light brown bark
Root: Woody root system
Fruit: Small, dark, single-seeded berry
Flowering Period: Varies with climate

Annual herb (Ranunculaceae), 20-90 cm tall, with an erect, branched stem and finely divided, pinnately dissected, fern-like leaves. Delicate pale blue-white (occasionally pale purple) flowers, each with 5-10 petal-like sepals, are surrounded by a feathery bract collar. The fruit is an inflated, many-celled capsule that dries and splits to release numerous small, black, angular seeds - the medicinal part.[1]

Habitat

Native to Sri Lanka and the Malabar coast of southern India; cultivated in warm, humid tropical lowlands, especially Sri Lanka, which remains the main source of true (Ceylon) cinnamon.

Native to the Mediterranean basin, southern Europe, western Asia and North Africa, and widely cultivated as a spice and medicinal crop across the Middle East, South Asia and North Africa; grows in cultivated fields and on disturbed ground.[1]

Harvesting

Young shoots are cut back to encourage thin, straight new growth; the thin outer bark is scraped away and the paper-thin inner bark is peeled off, dried and rolled by hand into the characteristic multi-layered quills of Ceylon cinnamon.

Parts: Bark

Seed capsules are harvested once dried and brown (late summer), then threshed to release the small black seeds. Seed is stored whole and either used directly or cold-pressed for oil shortly before use to preserve the volatile thymoquinone-rich fraction.[1]

Parts: Seed
Season: Late summer, once capsules have dried

Traditional Uses

True cinnamon bark has an ancient trade and medicinal history across Asia, the Middle East and Europe as a warming digestive and circulatory remedy, used for indigestion and as a general tonic spice; because it contains only trace coumarin, it is considered the safer species for frequent or medicinal use compared with cassia.[8]

One of the most celebrated medicinal seeds in Middle Eastern and Islamic traditional medicine - known as 'Habbatul Barakah' (the blessed seed) - black seed has traditionally been used for digestive complaints, respiratory conditions (asthma, cough), pain, inflammation, skin conditions and as a general tonic. Modern research on its principal constituent thymoquinone supports broad anti-inflammatory, antioxidant, antimicrobial, antidiabetic and immunomodulatory activity.[1, 2, 9]

Preparations

Standardised extract/powder[8]

Dried bark powder or standardised extract taken as capsules for metabolic and antioxidant support.

Decoction/infusion[9]

Comminuted bark infused in hot water as a herbal tea, 0.5-1 g up to four times daily per the EU herbal monograph. The monograph describes an infusion; it does not cover a simmered decoction. Educational reference only, not a prescription.

Whole or ground seed[1]

Seed eaten directly, sprinkled on food, or ground into a paste - the traditional culinary-medicinal form.

Cold-pressed seed oil[3, 9]

The form most used in clinical trials, taken orally in capsules or as a liquid.

Dosage

Bark powder[9]

The EU herbal monograph on Cinnamomum verum J.S. Presl, cortex gives, for adults and elderly, 0.5-1 g of the comminuted bark as an infusion up to 4 times daily; a liquid extract at 0.5-1 mL three times daily and a tincture at a daily dose of 2-4 mL are also listed. Not recommended under 18 years, and a practitioner should be consulted if symptoms persist beyond 2 weeks. Note this is Ceylon cinnamon (C. verum); cassia species carry a much higher coumarin load and are not covered here. Educational reference only, not a prescription.

Seed oil[12, 13, 14, 15, 16, 17, 18]

Clinical trials have generally been well tolerated at doses up to about 200 mg/day of oil taken for up to 90 days. Educational reference only, not a prescription; avoid medicinal doses in pregnancy.
