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
Multiple undescribed and known sesquiterpenoids and triterpenoids isolated from the leaves, several with anti-inflammatory activity.
Volatile oil containing thujone and other monoterpenes; thujone content is the basis of the caution on prolonged internal use.
Antioxidant and anti-inflammatory flavonoid and coumarin 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
Artemisia vulgaris (mugwort) extracts inhibit BCR/ABL and induce apoptosis, ferroptosis and necroptosis in chronic myeloid leukaemia and breast cancer cells (preclinical).
Traditional & Indicated Uses
inferred from anti-inflammatory action
Artemisia vulgaris (mugwort) extracts inhibit BCR/ABL and induce apoptosis in chronic myeloid leukaemia cells (including imatinib-resistant), and trigger tumour-selective ferroptosis/necroptosis in breast cancer and leukaemia cells via lysosomal Ca2+ signalling (preclinical).

Safety, Cautions & Contraindications
Contains thujone; avoid high doses or prolonged use. Contraindicated in pregnancy (uterine stimulant and abortifacient). May cause allergic reactions in individuals sensitive to the Asteraceae family. Avoid in epilepsy. Not recommended for children.
Duke (2002) rates mugwort as + (use with caution) and notes abortifacient (score 1), emmenagogue, aperitif (score 1), and insecticide activities. Duke clearly flags mugwort as contraindicated in pregnancy due to well-documented abortifacient and uterotonic properties. Traditional use has been as a digestive bitter, and the plant contains volatile oils, sesquiterpene lactones, and flavonoids. Duke notes that the plant may cause allergic reactions in individuals sensitive to Asteraceae and warns against long-term use due to potential neurotoxicity from thujone-containing essential oil (Duke, 2002).
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).

Botanical Description
Tall, aromatic perennial herb with deeply lobed, dark green leaves that are distinctively silvery-white and woolly beneath. Small, dull reddish-brown to yellowish flower heads are borne in dense, branched, leafy spikes. The reddish-brown, ridged stems and the leaf's contrasting silver underside are characteristic field marks.[3]
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.
Habitat
A common plant of waste ground, roadsides, hedgerows and riverbanks; native to Europe, Asia and North Africa and widely naturalised in North America.[3]
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.
Harvesting
The flowering aerial parts (leaf and stem) are cut in summer as flowering begins and dried in a warm, shaded, airy place; the root can be dug in autumn.[3]
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.
Traditional Uses
Mugwort is a widely used traditional bitter digestive tonic and calming nervine, and has a long reputation as an emmenagogue for menstrual complaints (reflected in its traditional use to bring on delayed menstruation, which is also why it is contraindicated in pregnancy). It has also been burned as 'moxa' in East Asian moxibustion and used as an insect repellent ('sailor's tobacco').[3]
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]
Preparations
Stigma extract standardised to safranal/crocin content, taken as capsules; the form used in most clinical mood and metabolic studies.
Dosage
Health Canada's NNHPD monograph gives 0.2-2.4 g of dried herb top, 3 times per day, for adults 18 years and older, with infusion and decoction among the accepted methods of preparation. Educational reference only, not a prescription.
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.
