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.
The volatile oil, dominated by 1,8-cineole and camphor, gives the characteristic aroma and much of the antimicrobial activity.
Potent antioxidant diterpenes considered largely responsible for rosemary's strong preservative and antioxidant activity.

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).
Culinary use is entirely safe. Essential oil should not be ingested in large amounts; avoid during pregnancy in medicinal doses. May trigger epileptic seizures in predisposed individuals at high doses. May interact with anticoagulants and antiplatelet drugs.
Duke (2002) does not appear to include a dedicated entry for rosemary (Salvia rosmarinus / Rosmarinus officinalis) as a primary herb entry in the section searched; however, rosemary is referenced throughout the text in relation to antioxidant and antimicrobial properties of its key compounds (carnosol, rosmarinic acid). Commission E (KOM) approves rosemary for dyspeptic complaints and externally for rheumatic conditions and circulatory problems.

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.
Evergreen, woody shrub (Lamiaceae), 1-2 m tall, with dense, needle-like, dark green, aromatic leaves, white-felted beneath. Small, pale blue to violet, two-lipped flowers are borne in the leaf axils.[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 the Mediterranean coast, growing on dry, rocky, sunny slopes and coastal scrub; widely cultivated as a culinary and medicinal herb worldwide, tolerating poor, well-drained soils and drought.[1]
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.
Leafy sprigs are cut throughout the year (the plant is evergreen), though essential-oil content is often considered highest just before or during flowering; leaves are stripped from the stem and dried, or used fresh.[1]
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]
Rosemary has an ancient Mediterranean reputation as a memory and circulation tonic ('rosemary for remembrance'), a digestive carminative, and an antiseptic for minor wounds. Commission E approves it for dyspeptic complaints internally and for rheumatic conditions and circulatory problems externally; modern research on rosmarinic acid and carnosic acid supports antioxidant, anti-inflammatory, antimicrobial and cognitive-supportive activity.[1]
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.
Commission E approves rosemary for dyspeptic complaints (internal use) and, externally, for rheumatic conditions and circulatory problems; typical internal use is roughly 2-4 g dried leaf as tea, up to three times daily. Educational reference only, not a prescription; avoid concentrated essential oil internally and in pregnancy/epilepsy.
