Key Constituents
Water-soluble carotenoid glycosides responsible for saffron's deep golden-red colour and much of its antioxidant and mood-related activity.
The principal volatile aromatic compound, giving saffron its characteristic scent and contributing to its sedative and antidepressant activity.
The main bitter-tasting glycoside of the stigma, a precursor of safranal.
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
Culinary use is entirely safe. At very high doses (5g+), saffron can be toxic — but such doses far exceed culinary or therapeutic amounts. Avoid medicinal doses during pregnancy (uterine stimulant). May interact with antidepressants. High quality saffron is often adulterated; verify source.
Duke (2002) rates saffron as ++ and provides a critical safety warning: abortifacient activity has clinical support (score 2), meaning that medicinal doses can induce abortion — saffron is strictly contraindicated in pregnancy at doses above culinary amounts. The plant also shows antidepressant, antioxidant, and antitumor activities at the experimental level (score 1). Dose (culinary): 0.5 g stigmas as flavoring; medicinal doses above 5 g are considered potentially toxic. Duke notes that saffron stigmas contain crocin and safranal, which are responsible for its antidepressant and antioxidant properties (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
Small, cormous perennial with narrow, grass-like, dark green leaves emerging with or just after the flowers. Each flower is a delicate lilac-purple, six-petalled bloom with three golden-yellow anthers and a single style dividing into three long, deep-red, thread-like stigmas - the saffron of commerce. The plant is a sterile triploid that never sets seed and is propagated entirely by division of its underground corms.
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
Believed to have originated in Greece or Crete and spread through cultivation across the Mediterranean, Middle East and Asia (notably Iran, Kashmir and Spain); grown in sunny, well-drained fields with hot, dry summers and cool, wet autumns/winters.
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 flowers are hand-picked at dawn as they open, and the three red stigma threads are immediately hand-separated from each flower and dried - an extremely labour-intensive process (many thousands of flowers are needed for a small amount of dried saffron), which accounts for saffron's high cost.
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
Saffron has a long Mediterranean, Middle Eastern and South Asian tradition as both a prized culinary spice/dye and a medicinal herb, used for mood support, digestive complaints and as a mild emmenagogue; its traditional mood-lifting reputation is now supported by clinical trials comparing standardised saffron extract to conventional antidepressants for mild-to-moderate depression.[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
Stigma extract standardised to safranal/crocin content, taken as capsules; the form used in most clinical mood and metabolic studies.
Dosage
Clinical trials for mood support commonly use around 30 mg of standardised saffron extract daily (in divided doses); culinary use is typically well under 1 g. High medicinal doses (5 g or more) are considered potentially toxic and should be avoided. 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.
