Key Constituents
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.
Anti-inflammatory and antimicrobial constituents.
Coat and protect inflamed mucous membranes and reduce cough-receptor sensitivity.
Antioxidant and anti-inflammatory constituents.
Pharmacological Actions
Anti-inflammatory for temporary mild inflammation of the mouth and throat (sore throat); in vitro the extract inhibits nitric oxide production and inducible NOS in macrophages, supporting its traditional respiratory anti-inflammatory use
Demulcent for catarrh of the respiratory tract and dry, irritating cough / bronchitis (mucilage soothes and protects irritated airways)

Safety, Cautions & Contraindications
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
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]
Perennial herb (Plantaginaceae) forming a low rosette of narrow, lance-shaped leaves with prominent parallel ribs (hence 'ribwort'). Slender, furrowed, leafless flowering stalks rise from the rosette bearing a dense, short, dark brown-black ovoid to cylindrical flower spike ringed by a 'collar' of protruding cream-white stamens.[11]
Habitat
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]
Native throughout Europe and temperate Asia and naturalised worldwide; common in grassland, meadows, lawns, roadsides and waste ground, tolerating trampling and a wide range of soils.[11]
Harvesting
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]
Leaves and aerial parts are gathered during the growing season, ideally before or during flowering, and dried quickly.[11]
Traditional Uses
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]
Ribwort plantain has an official European herbal-monograph tradition for the temporary relief of dry cough and irritation of the mouth and throat, and for minor skin wounds, reflecting its long folk use as a demulcent respiratory remedy and wound herb. Modern research confirms mucilage-driven demulcent action alongside antimicrobial and anti-inflammatory activity.[11, 12]
Preparations
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
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.
