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.
Pharmacological Actions
Adaptogen for stress and anxiety (improves stress scores and well-being in trials)
Cognitive support - a placebo-controlled study in healthy adults found improved reaction time and accuracy and shorter P300 latency

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 well tolerated; mild nausea has been reported. Its blood-sugar-lowering effect means caution alongside antidiabetic medicines.

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.
Aromatic annual or short-lived perennial subshrub (Lamiaceae), 30-75 cm tall, with erect, much-branched, hairy stems often tinged purple. Leaves are opposite, ovate-oblong with a toothed margin, and release a strong, clove-like (eugenol) scent when crushed. Small purplish-pink, two-lipped flowers are borne in elongated terminal racemes. The plant is held sacred in Hindu tradition (Tulsi).[11]
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 the Indian subcontinent and tropical Asia, now cultivated and naturalised throughout the tropics and subtropics worldwide; commonly grown in home gardens and temple courtyards as well as cultivated as a medicinal and aromatic crop.[12]
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.
Leaves are harvested year-round from actively growing plants, ideally picked once morning dew has dried; whole flowering tops are also gathered.
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]
Tulsi is one of the most revered plants in Ayurvedic medicine, traditionally used as an adaptogen for stress, a remedy for respiratory complaints (colds, cough, asthma), and a general immune tonic. Modern clinical trials support adaptogenic/anti-stress, blood-sugar-lowering and immunomodulatory effects consistent with these traditional uses.[3, 12]
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.
Clinical trials for stress and mood have used standardised dry-extract capsules taken over several weeks; dosing varies by product concentration, so follow the manufacturer's guidance. Educational reference only, not a prescription.
The WHO monograph on Folium Ocimi Sancti gives a daily dosage of 6-12 g of the crude drug as a decoction. This is a whole-day total for the fresh or dried leaf, notably higher than the 1-2 g per cup often quoted in popular sources. Educational reference only, not a prescription.
