Evidence scores (1–10) are computed from the tier of each cited source. “Comparable” means the two scores are within one point. Follow a score to its detailed sources.
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.
Antioxidant flavonoids of the leaf, standardised in clinical extracts.
Unique diterpene and sesquiterpene lactones responsible for platelet-activating-factor antagonism and much of the neuroprotective and circulatory activity; also the basis of the bleeding-risk caution.
A neurotoxic compound present in the raw seed; the reason only cooked seed in small amounts, or standardised leaf extract, is used medicinally.

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 at standard doses but notable interactions exist. Ginkgo has antiplatelet and anticoagulant effects and should not be combined with warfarin, aspirin, or other blood-thinning medications without medical supervision. May lower the seizure threshold — avoid in epilepsy. Possible side effects include headache, dizziness, and GI upset. The raw seeds contain ginkgotoxin and are toxic; only processed leaf extracts are used medicinally.
Duke (2002) rates ginkgo as + (downgraded from higher rating for safety concerns) while noting clinical evidence (score 2) for anti-aggregant (platelet-inhibitory), anti-Alzheimer, and antioxidant activities. Commission E approves ginkgo leaf extract for cognitive deficits, peripheral circulatory disorders, and vertigo. However, Duke emphasizes significant safety concerns: ginkgo substantially increases bleeding risk when combined with anticoagulants (warfarin, aspirin, NSAIDs) and may cause spontaneous bleeding at high doses alone. Dose: 120–240 mg standardized extract (EGb 761) daily. Contraindicated with anticoagulants without medical supervision (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.
Ancient deciduous tree, a 'living fossil' with no close living relatives, bearing distinctive fan-shaped leaves with parallel forking veins that turn brilliant gold in autumn. The tree is dioecious (separate male and female trees); female trees bear fleshy, foul-smelling seed coats surrounding an edible inner nut (ginkgo nut) once the outer flesh is removed.[2]
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 China, where a small number of wild populations survive; now cultivated worldwide as a resilient, pollution-tolerant ornamental and medicinal tree.
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 picked in late summer to autumn, when flavonoid and terpenoid content is highest, and processed into standardised extracts; the inner seed is collected in autumn from fallen fruit, with the malodorous outer flesh removed (handled with gloves, as it can irritate skin).
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]
Ginkgo leaf and seed have a long East Asian tradition: the seed used in traditional Chinese medicine (in small, cooked amounts) for respiratory complaints, and the leaf, though a more recent addition to Western herbalism, now one of the most extensively studied botanicals for cognitive and peripheral circulatory support, reflecting decades of standardised-extract clinical research.[2]
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 cognitive and circulatory support commonly use around 120-240 mg of standardised leaf extract daily, in divided doses. Educational reference only, not a prescription.
