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.

Safety, Cautions & Contraindications

Safety note[15, 16, 17]Caution

Generally very safe. Rarely causes contact dermatitis in sensitive individuals (sesquiterpene lactones, same Asteraceae family). Avoid high doses during pregnancy (emmenagogue at large doses). May increase photosensitivity. Allergic reactions uncommon but possible in those sensitive to Asteraceae plants.

Safety note[15, 16, 17, 22]Caution

Duke (2002) rates yarrow as ++ with clinical evidence (score 2) for antibacterial, antiseptic, antispasmodic, choleretic, aperitif, and astringent activities, consistent with Commission E (KOM) approval for loss of appetite and dyspeptic ailments. Yarrow contains achillin, achilleic acid, and apigenin — compounds with anti-inflammatory and hemostatic properties. Traditional use for wound healing, fever management, and digestive complaints is well-supported. Dose: 2–4 g dried herb as tea three times daily. Caution: yarrow belongs to the Asteraceae family and can cause allergic reactions in sensitive individuals; rare contact dermatitis from sesquiterpene lactones has been reported. Contraindicated in pregnancy due to potential emmenagogue effects (Duke, 2002).

Safety note[12]Info

As a member of the daisy family (Asteraceae) it can cause allergic reactions or contact dermatitis in sensitive people, and handling the fresh plant in sunlight can occasionally cause photosensitivity.

Safety note[14]Caution

Medicinal use is traditionally avoided in pregnancy (can stimulate the uterus and influence menstruation); caution while breastfeeding.

Safety note[12]Caution

May interact with anticoagulant, sedative and blood-pressure medications and with drugs metabolised by the liver; seek professional advice if on regular medication.

Safety note[12, 23]Info

Correct identification is essential, as several poisonous white-flowered umbellifers can be confused with yarrow; clinical evidence in humans is limited.

Safety note[24, 25, 26, 27, 28, 29, 30, 31, 32, 33]Info

Additional omniasana.bio sources cited for Achillea millefolium (identification, distribution, foraging, traditional use and supporting evidence; see bibliography).

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).

Botanical Description

Aromatic, rhizomatous perennial herb with erect, grooved, softly hairy stems arising in clumps from a creeping rootstock. The leaves are alternate, 2-3-pinnately dissected into narrow feathery segments, giving the whole plant a soft, fern-like texture (hence 'millefolium', thousand-leaved). Numerous small white to pale-pink flower heads are borne in dense, flat-topped compound corymbs at the stem tips. The plant has a sweet, herbaceous, slightly medicinal aroma when crushed.[12]

Height: 20-100 cm (occasionally to 1 m)
Habit: Erect, rhizomatous, mat-forming perennial herb
Leaves: Alternate, 2-3-pinnately dissected into narrow feathery segments; aromatic when crushed
Flowers: Small white to pale pink flower heads in dense, flat-topped compound corymbs
Stem: Erect, grooved, softly hairy/woolly, plain green (never purple-blotched)
Root: Creeping, fibrous rhizome
Fruit: Small flattened achenes without pappus
Flowering Period: June-September

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

Habitat

A common plant of grassland, meadows, roadsides, pastures and waste ground on a wide range of soils; native throughout Europe and temperate Asia and now naturalised across North America, Australia and New Zealand.[12]

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.

Harvesting

The flowering aerial parts (leaf, stem and flower) are cut as the flat-topped corymbs open, in mid- to late summer, and dried quickly in a warm, shaded, airy place to preserve the essential oil and colour.[12]

Parts: Flower, Leaf, Stem
Season: Summer, at full flower (June-September)

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

Traditional Uses

Yarrow has an ancient reputation as a wound herb (its old name 'staunchweed' and its association with Achilles reflect traditional use to stop bleeding and heal wounds) and as a bitter digestive and diaphoretic remedy for feverish colds, spasmodic gastrointestinal complaints, hepatobiliary disorders and gynaecological complaints. The flowering herb is classically taken as a hot infusion at the onset of a cold or fever to promote sweating, and used as a bitter tonic to stimulate appetite and digestion.[2, 12]

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]

Preparations

Infusion[12]

Dried flowering herb infused in hot water as a bitter digestive and diaphoretic tea, traditionally taken hot at the onset of colds and fevers.

Tincture[13]

Tincture of the herb, ethanol 45% V/V, 2-4 ml three times daily. The EU herbal monograph gives the ethanol strength but states no drug-extract ratio, so no 1:5 ratio is claimed here. Educational reference only, not a prescription.

Poultice/compress[10, 12]

Fresh crushed leaf or flowering tops applied directly to minor cuts and wounds, reflecting the traditional styptic (bleeding-stopping) and vulnerary use.

Essential oil[12]

Steam-distilled from the flowering tops; the chamazulene-rich blue oil is used in low dilution for its anti-inflammatory action.

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.

Dosage

Dried herb infusion[13, 14]

The EU herbal monograph gives 1.5-4 g of the comminuted herb in 150-250 mL of boiling water as an infusion, three or four times daily between meals; for loss of appetite the liquid preparations are taken 30 minutes before meals. Educational reference only, not a prescription.

Tincture (ethanol 45% V/V)[13]

The EU herbal monograph gives 2-4 mL three times daily in adolescents, adults and elderly. Educational reference only, not a prescription.

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.

Dangerous Lookalikes

Safety note[34, 35, 36]Fatal
Dangerous Plant: conium-maculatum
Confused Part: Young feathery, finely divided leaves gathered for tea, salad or medicine; poison hemlock's young leaves are also feathery and finely divided.
Confusion Context: Yarrow (Achillea millefolium) is foraged for its soft, feathery, fern-like leaves. As Grow Forage Cook Ferment warns, yarrow is sometimes mistaken for poison hemlock (Conium maculatum), which is very toxic - hemlock contains coniine and kills by ascending paralysis and respiratory failure, and a few leaves can be fatal. Young hemlock leaves are more feathery and can resemble yarrow before the plant grows tall. Because yarrow is a popular forage and hemlock is widespread, this is a potentially fatal confusion.
Distinguishing Features: SMELL: yarrow smells sweet and herbaceous, often likened to fresh pine or a pleasant medicinal scent. Poison hemlock smells rank and musty/mousy., Stem: yarrow has a solid, green, slightly hairy/woolly grooved stem with no purple. Poison hemlock has a hairless stem conspicuously blotched and streaked with red-purple, especially near the base., Leaf and size: yarrow leaves are soft, very finely divided and feathery on a low plant (usually under 60 cm). Poison hemlock is a tall (1.5-3 m) branching biennial with larger, glossy, more open fern-like leaves.
Key Test: Check the stem and smell. A solid green (often woolly) stem with soft feathery leaves and a sweet pine-like herbaceous scent = yarrow. A hairless stem with red-purple blotches and a musty/mousy smell = poison hemlock - deadly, do not put it to your mouth. If the stem is purple-blotched or the smell is musty, do not use it.
