Evidence scores (1–10) are computed from the tier of each cited source. “Comparable” means the two scores are within one point. Follow a score to its detailed sources.
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.
Lipophilic alkamides are considered key immunomodulatory and anti-inflammatory constituents, particularly concentrated in the root.
Antioxidant phenolic compounds contributing to the plant's immunomodulatory activity.
Water-soluble polysaccharides associated with immune-stimulating activity, particularly from the aerial parts.

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).
Generally considered safe, but caution advised for those with autoimmune conditions. Not recommended for long-term use (more than 8 weeks continuously).
Duke (2002) rates echinacea as +++ — among the most thoroughly documented herbal immunostimulants. It notes experimental and clinical evidence for immunostimulant, antiviral, and anti-inflammatory activities. Multiple species have been studied (E. purpurea, E. angustifolia, E. pallida), and Duke emphasizes that species identification in commercial products is often unreliable. Commission E approves E. purpurea for supporting immune function during colds and flu. Dose: 900 mg standardized extract daily in acute use; use should be limited to 8 weeks continuous. Contraindicated in autoimmune diseases (MS, lupus, HIV/AIDS), tuberculosis, and with immunosuppressive drugs (cyclosporine) (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.
Robust perennial herb with a basal rosette of coarse, hairy, lance-shaped leaves and tall, sturdy flowering stems. Each stem bears a single large, daisy-like flower head with drooping (reflexed), rose-purple to pink ray florets surrounding a prominent, spiny, orange-brown central cone of disc florets.[4]
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 tallgrass prairies, open woodland and dry meadows of central and eastern North America; widely cultivated worldwide as a garden and medicinal plant.[4]
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 flower heads are picked as they open, in summer; the root is dug in autumn from plants at least two to three years old, when its content of bioactive alkamides and caffeic acid derivatives is highest, then cleaned and dried.[4]
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]
Echinacea root was widely used by Native American peoples as a remedy for infections, wounds, snakebite and toothache, and entered nineteenth-century Eclectic medicine as a broad anti-infective. It remains best known today, in standardised aerial-part or root extracts, as a supportive remedy for preventing and shortening the common cold and supporting immune function.[1, 4]
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.
Fresh-pressed juice or standardised extract of the aerial parts or root, taken as tablets, drops or capsules at the first sign of a cold; the best-studied clinical form.
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.
Clinical trials for the common cold commonly use around 300-900 mg of standardised extract daily, started at the first sign of symptoms and continued for up to 7-10 days; continuous use beyond about 8 weeks is not recommended. 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]
