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
Isoquinoline alkaloids - berberine (principal), hydrastine and canadine[1, 4, 12]

Berberine is the main antimicrobial, hypoglycaemic and hypolipidaemic constituent. Notably, whole-leaf extracts are more potent against MRSA than isolated berberine (owing to efflux-pump-inhibitory flavonoids) and show quorum-quenching, anti-virulence 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[1]Caution

Contraindicated in pregnancy and breastfeeding: berberine crosses the placenta and into milk and can cause or worsen newborn jaundice (risk of kernicterus); do not give to infants.

Safety note[1, 14]Caution

Berberine strongly inhibits drug-metabolising enzymes (especially CYP3A4 and CYP2D6), so it can raise the blood levels of many medicines - a significant herb-drug-interaction risk. In a screen of commercial herbal products, goldenseal was among the most potent CYP2D6 inhibitors and also inhibited CYP3A4. High doses have shown possible liver, nerve and photo-toxicity.

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

Low, woodland perennial herb rising from a knotted, bright yellow rhizome with wiry yellow roots. Each stem bears two ragged, palmately lobed, maple-like leaves and a single small, inconspicuous greenish-white flower, followed by a raspberry-like cluster of red berries.[1]

Height: 15-30 cm
Habit: Low, woodland perennial herb
Leaves: Two per stem, ragged, palmately lobed, maple-like
Flowers: Single, small, inconspicuous, greenish-white, petal-less
Stem: Hairy, upright, bearing two leaves
Root: Knotted, bright yellow rhizome with wiry yellow roots (the medicinal part)
Fruit: Raspberry-like cluster of red berries
Flowering Period: April-May

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.

Grows in rich, shaded deciduous woodland with humus-rich soil; native to eastern North America, now scarce in the wild due to overharvesting and largely supplied by cultivation.[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

The rhizome and root are dug in autumn from plants at least three to four years old, when berberine content is highest, then cleaned and dried; because wild populations are depleted, cultivated or sustainably sourced material is strongly preferred, and careful identification against the toxic mayapple and bloodroot, which share its woodland habitat, is essential before any wild-harvesting.[1]

Parts: Rhizome and root
Season: Autumn, from mature (3-4+ year) plants

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]

Goldenseal root has a Native American and, after adoption by Eclectic physicians, wider North American tradition as a bitter tonic and antimicrobial remedy for mucous-membrane infections, sore throat, digestive upset and topical skin infections, directly reflecting its high berberine content.[1]

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.

Decoction[1]

Dried rhizome and root simmered in water as a traditional bitter antimicrobial tea, or used as a gargle for sore throat.

Tincture[13]

Tincture 1:10 in 60% ethanol of the dried rhizome and root, 2-4 ml three times daily per the WHO monograph Rhizoma Hydrastis. Educational reference only, not a prescription.

Standardised extract[4]

Extract standardised to berberine/hydrastine content, taken as capsules; whole-leaf extracts have shown stronger antimicrobial activity than isolated berberine in some studies.

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.

Decoction/tincture[13]

The WHO monograph on Rhizoma Hydrastis gives a daily dose of 0.5-1.0 g of the dried rhizome and root three times, or taken as a decoction; a 1:1 liquid extract in 60% ethanol at 0.3-1.0 mL three times; or a 1:10 tincture in 60% ethanol at 2-4 mL three times. For short-term use only, given goldenseal's potent CYP-enzyme inhibition and its contraindication in pregnancy. Educational reference only, not a prescription.

Drug Class Interactions

Safety note[17, 18]Caution
Drug Class: antidiabetics
Mechanism: Cinnamon can lower blood sugar (a meta-analysis of 28 trials in type 2 diabetes found reduced fasting glucose and HbA1c), so combining it with diabetes medicines such as insulin, metformin or sulfonylureas may increase the risk of hypoglycaemia; monitor blood glucose.

Safety note[15, 16]Caution
Drug Class: cyp3a4-substrates
Mechanism: Goldenseal's berberine and hydrastine strongly inhibit CYP3A4 (and also CYP2D6), enzymes that clear many medicines. In a controlled study in healthy volunteers, 28 days of goldenseal cut CYP3A4/5 and CYP2D6 activity by roughly 40%, so it can raise the blood levels and side effects of drugs handled by these pathways - for example some statins, calcium-channel blockers and sedatives (CYP3A4), and certain antidepressants, beta-blockers and opioids (CYP2D6). Separate dosing and monitor, or avoid combining with narrow-margin medicines.

Drug Class: antidiabetics
Mechanism: Goldenseal is rich in berberine, its main alkaloid, which lowers blood glucose - meta-analyses of randomised trials show berberine significantly reduces fasting glucose and HbA1c. Taken with diabetes medicines, goldenseal may therefore add to blood-sugar lowering, so monitor blood glucose.

Dangerous Lookalikes

Not documented

Safety note[18, 19]Dangerous
Dangerous Plant: podophyllum-peltatum
Confused Part: Woodland rhizome dug as goldenseal; mayapple shares the same rich woods and has similar lobed, maple-like leaves.
Confusion Context: Goldenseal (Hydrastis canadensis) is dug from rich woodland for its yellow rhizome. Mayapple (Podophyllum peltatum) grows in the same rich-woods habitat and, once its leaves expand, its lobed maple-like leaves resemble goldenseal, so novice foragers confuse them. Mayapple contains podophyllotoxin (a potent cell poison) in all parts except the ripe fruit; ingestion causes severe vomiting and diarrhoea and can cause serious systemic toxicity. Because the plants share habitat and leaf shape, this is a genuine hazard when digging goldenseal.
Distinguishing Features: Whole plant: goldenseal has a hairy upright stem bearing usually two ragged, maple-like lobed leaves and a single small flower, with a knotted BRIGHT-YELLOW rhizome. Mayapple has one or two large, smooth, umbrella-like lobed leaves on a hairless stalk and a white flower nodding beneath, with a white-ish creeping rhizome., Rhizome colour (decisive): goldenseal's rhizome and root are vivid yellow inside (berberine). Mayapple's rhizome is not bright yellow., Leaf texture: goldenseal leaves are hairy and puckered; mayapple leaves are large, smooth and shield-like (the stalk joins near the centre).
Key Test: Dig only after matching the whole plant, and check the rhizome. A hairy stem with ragged maple-like leaves over a BRIGHT-YELLOW knotted rhizome = goldenseal. Large smooth umbrella-like leaves over a pale rhizome (no yellow) = mayapple - toxic, do not use. If the root is not bright yellow inside, do not use it.

Dangerous Plant: sanguinaria-canadensis
Confused Part: Woodland rhizome dug as goldenseal; bloodroot grows in the same rich woods and its rhizome is gathered in mistake for goldenseal.
Confusion Context: Bloodroot (Sanguinaria canadensis) shares the same rich-woods spring habitat as goldenseal and is listed among goldenseal's harvesting look-alikes. Bloodroot is a high-severity poison: its rhizome contains isoquinoline alkaloids (sanguinarine) and, when broken, oozes a bright red-orange sap; ingestion causes vomiting, faintness, dizziness, dilated pupils and, in serious cases, heart failure, and the sap is destructive to tissue. Because both are dug for their rhizomes from the same woodland, this is a genuine hazard.
Distinguishing Features: Sap colour (decisive): a broken bloodroot rhizome bleeds a bright RED-ORANGE sap. Goldenseal's rhizome is BRIGHT YELLOW inside, not red., Leaf: bloodroot has a single, rounded, deeply scalloped/lobed grey-green leaf that wraps the flower stalk, and a white flower; goldenseal has a hairy stem with two ragged maple-like leaves., Whole plant: confirm goldenseal by its paired hairy maple-like leaves and yellow root before digging.
Key Test: Break the rhizome and look at the sap and leaves. Bright YELLOW root with paired hairy maple-like leaves = goldenseal. A single scalloped leaf and a rhizome bleeding RED-ORANGE sap = bloodroot - a high-severity poison, do not use. If the sap is red, it is not goldenseal.
