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.
A major phytochemical class of noni fruit and leaf, studied for antioxidant and anti-inflammatory activity.
Found mainly in the root and, at lower levels, the fruit; studied for anticancer and antimicrobial activity.
Fruit polysaccharides studied for gut-microbiota-modulating and anti-inflammatory effects in animal models of inflammatory bowel disease.
A phenolic coumarin found in the fruit, studied for anti-inflammatory and vascular effects.

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).
Generally safe in moderate amounts. High potassium content — use caution in renal disease. Rare cases of hepatotoxicity reported with excessive consumption. May interact with warfarin (due to vitamin K content). Avoid during pregnancy.
Duke (2002) rates noni as +++ and notes analgesic, antirheumatic, antiarthritic, antitumor, antispasmodic, and hypotensive activities at the experimental level (score 1). Traditional Polynesian and South Asian medicine values it as a broad-spectrum tonic. The plant contains morindine, proxeronine, and damnacanthal, which are under investigation for immunomodulatory and anti-tumor effects. Duke notes that noni fruit can be consumed as food and is generally safe, though the juice has a strong unpleasant odor and taste. No significant toxicity has been reported with regular food consumption (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]
Small evergreen tree or shrub (Rubiaceae), 3-10 m tall, with large, glossy, dark green, elliptical leaves marked by prominent parallel veins. Small, white, tubular, fragrant flowers are borne in dense rounded heads, developing into a compound fleshy fruit (syncarp) that is warty, semi-translucent and yellow-white when ripe, with a strong, pungent, cheese-like odour.[1]
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 to Southeast Asia and Australasia, and dispersed across the Pacific islands and into India and the Caribbean by early Polynesian voyagers and subsequent cultivation; grows in coastal areas, open and disturbed forest, and even on bare lava flows, tolerating poor, saline and drought-prone soils.[1, 6]
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]
Ripe fruit is hand-picked as it softens and turns yellow-white, then traditionally left to further ripen or ferment for juice production; leaves and root are also traditionally gathered.[6]
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]
Noni has an extensive Polynesian, South Asian and Southeast Asian traditional-medicine history, used as a broad-spectrum tonic for pain, inflammation, infection and immune support, and traditionally for diabetes and skin complaints. The fermented fruit juice is the most widely used modern preparation, now studied for antioxidant, anti-inflammatory, immunomodulatory and metabolic effects supporting several of these traditional uses.[1, 6]
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.
Commercial noni juice is typically taken in modest daily amounts (a few tablespoons); given rare reports of hepatotoxicity with excessive or prolonged intake, avoid high doses, especially with pre-existing liver disease. Educational reference only, not a prescription.
