Key Constituents
The pungent alkaloid-like compounds responsible for the fruit's heat and its counterirritant/analgesic action via TRPV1 receptor desensitisation.
Give ripe red fruit its colour and contribute antioxidant and anti-inflammatory activity.
Antioxidant and anti-inflammatory flavonoids identified in leaf and fruit extracts.
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.

Safety, Cautions & Contraindications
Capsaicin causes intense burning sensation; avoid contact with eyes and mucous membranes. High oral doses can cause gastrointestinal irritation, nausea, and diarrhoea. Topical preparations may cause skin irritation and should be used diluted. Not recommended for individuals with active peptic ulcers. Caution with anticoagulants — capsaicin may enhance bleeding risk. During pregnancy, culinary amounts are considered safe, but high-dose supplements should be avoided. Repeated topical application leads to desensitisation (TRPV1 depletion), which is the basis for its analgesic use. Children under 2 should not be given capsaicin-containing topical products (Basu and Bhattacharyya, 2023).
Duke (2002) rates cayenne/chili pepper (Capsicum annuum) highly for its clinically documented analgesic, counterirritant, and rubefacient activities. Commission E approves topical capsaicin preparations for muscle pain, arthritis, and neuralgia (score 2). The active compound capsaicin depletes substance P in sensory neurons upon repeated application, reducing pain signals. Capsaicin cream (0.025–0.075%) is a validated treatment for post-herpetic neuralgia, diabetic neuropathy, and osteoarthritis pain. Internal use can irritate mucous membranes; external use requires avoiding contact with eyes and mucous membranes (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
Bushy annual or short-lived perennial herb (grown as an annual in temperate climates) with glossy, oval to lance-shaped leaves. Small, star-shaped, white to greenish flowers give way to the characteristic fleshy, hollow fruit (a berry), which ripens from green through yellow to red and varies enormously in size, shape and pungency between cultivars.[1]
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 Central and South America; cultivated worldwide in warm and temperate climates as a food and medicinal crop, thriving in full sun on well-drained soil.[1]
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
Fruit is picked at the desired stage of ripeness (green for milder use, fully red for maximum capsaicin and carotenoid content) through summer and autumn; seeds are separated and dried from fully ripe fruit.
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
Chili pepper fruit has a long history across the Americas and, after global spread, in many other traditional medicine systems as a warming digestive stimulant and topical counterirritant/analgesic for muscle and joint pain, building on capsaicin's now well-documented ability to desensitise pain-sensing nerve fibres with repeated application.[1]
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
Standardised capsaicin cream or patch applied to the affected area for muscle, joint or nerve pain; repeated application depletes substance P and reduces pain signalling.
Dosage
The EU herbal monograph on Capsici fructus gives semi-solid dosage forms corresponding to 40-53 mg capsaicinoids per 100 g, applied as a thin layer to the affected area 2-4 times daily, in adults and elderly. For medicated plasters, a maximum of 1 plaster per day applied for at least 4 and up to 12 hours, with at least 12 hours before a new plaster is applied to the same area. Not recommended under 18 years. Expect an initial burning sensation that lessens with repeated use. Note the monograph covers hot chilli fruit (C. annuum var. minimum and small-fruited C. frutescens), not sweet peppers. 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.
