Key Constituents
Diosgenin is an industrial precursor for making steroid hormones in the laboratory, but it is NOT converted into hormones in the human body. Oral bioavailability of diosgenin is low; in animal studies orally administered diosgenin restored skin thickness in ovariectomised mice and lowered blood lipids.
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.
Pharmacological Actions
Antispasmodic / analgesic for menstrual cramps and muscle spasm (antinociceptive in animal models)
Anti-inflammatory for joint and inflammatory pain

Traditional support for menopausal symptoms (see safety note - it does NOT act as a natural progesterone) - a placebo-controlled crossover RCT of topical wild yam cream found little effect on menopausal symptoms, lipids or hormones

Safety, Cautions & Contraindications
IMPORTANT myth-bust: wild yam / diosgenin is NOT converted into progesterone or DHEA in the body, so it does not work as a 'natural progesterone' - claims to that effect are incorrect. Consistent with this, a randomized placebo-controlled crossover trial of topical wild yam cream found no significant change in symptoms, serum/salivary progesterone, oestradiol, FSH or lipids.
Generally well tolerated orally (no acute or subchronic toxicity in animal studies); large doses may cause nausea or vomiting. Avoid medicinal doses in pregnancy and breastfeeding and in hormone-sensitive conditions as a precaution.
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
Twining, herbaceous perennial vine with heart-shaped leaves arising from a knotty, woody, cinnamon-brown rhizome ('root'). Small, inconspicuous greenish-yellow flowers are borne on separate male and female plants, followed on female plants by small three-winged seed capsules.[10]
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 woodland edges, thickets and fence rows of eastern North America, growing over shrubs and fences in moist, rich soil.[10]
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 knotty rhizome is dug in autumn once the aerial vine has died back, then cleaned and dried.
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
Wild yam root has a Native American and Eclectic-medicine history as an antispasmodic remedy for colic, menstrual cramps and rheumatic joint pain (reflected in the old names 'colic root' and 'rheumatism root'); despite a persistent modern myth, its diosgenin content is not converted into progesterone or other hormones in the human body.[10]
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]

Dosage
Not documented
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.
