Key Constituents
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.
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.
Seed essential oil dominated by 1,8-cineole and alpha-terpinyl acetate, giving the characteristic aroma and much of the carminative, antimicrobial and antioxidant activity.
Additional antioxidant constituents of the seed.

Safety, Cautions & Contraindications
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.
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).
Cardamom is generally considered safe for most people when used in culinary amounts. At medicinal doses (supplement form), rare side effects include mild gastrointestinal discomfort and allergic reactions. There are no well-documented serious drug interactions at culinary doses. Cardamom may mildly lower blood pressure — caution if combined with antihypertensive medications. Some sources suggest potential gallstone formation with very high doses, as cardamom may stimulate bile flow. Avoid therapeutic doses during pregnancy until more safety data are available; culinary use is considered safe. Allergy to other Zingiberaceae (ginger, turmeric) may indicate cross-reactivity risk (Korikanthimath and Hiremath, 2002).
Duke (2002) provides clinical support (score 2) for cardamom as a cholagogue, antiviral agent, and appetite stimulant. Commission E and the German PDR (PHR) approve it for loss of appetite and bronchitis (score 2). The essential oil shows antispasmodic and carminative activity. Dose: 1.5 g ground fruit or equivalent preparation three times daily. Duke rates cardamom as generally safe (++), with no significant contraindications at therapeutic doses (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.
Large, rhizomatous perennial herb with tall, reed-like leafy stems (pseudostems) formed by overlapping leaf sheaths, arising from a stout underground rhizome. Small, pale flowers with a violet-veined white lip are borne on separate trailing panicles that grow along the ground from the base of the plant. The fruit is a small, ridged, pale green three-sided capsule (the cardamom pod) containing numerous dark, aromatic seeds.[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 moist evergreen forests of the Western Ghats of southern India and Sri Lanka; cultivated in warm, humid, shaded tropical conditions, notably in India, Guatemala and Sri Lanka.[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.
The unripe green pods are hand-picked just before full maturity, then carefully dried (traditionally in the shade or by gentle heat) to preserve the green colour and aromatic oil; the pods are typically used whole or the seeds removed and ground just before use.
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]
Cardamom has a long Ayurvedic, Middle Eastern and Asian tradition as a warming digestive carminative for indigestion and bloating, a remedy for respiratory complaints such as asthma and bronchitis, and a valued spice for tea, coffee and cooking.[1]
Preparations
Dried bark powder or standardised extract taken as capsules for metabolic and antioxidant support.
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.
Crushed pods or seeds infused in hot water, or added to tea/coffee, as a traditional carminative digestive preparation.
Dosage
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.
The WHO monograph on Semen Cardamomi gives an average DAILY dosage of 1.5 g of the drug, or equivalent preparations; for tincture, a daily dosage equivalent to 12 g. Note the 1.5 g is a daily total, not a per-dose amount. Educational reference only, not a prescription.

Pairings
Cinnamon and fenugreek can each lower blood sugar, so taking them together — especially alongside diabetes medicines — may add up and increase the risk of blood sugar dropping too low (hypoglycaemia). Monitor your blood glucose.[18, 19]
Cinnamon and bitter melon can each lower blood sugar, so taking them together — especially alongside diabetes medicines — may add up and increase the risk of hypoglycaemia. Monitor your blood glucose.[18, 20]
