Crocus sativus
Pronounced Saffron: SAF-ruhn. Kesar: KAY-sar. Crocus sativus: KROH-kus sa-TEE-vus.
Warm, dry, and moving: a precious blood-mover and spirit-lifter that dispels stagnation and melancholy, therapeutic in milligrams and toxic in grams.
Avoid in medicinal amounts (likely unsafe). Saffron is a documented uterine stimulant and traditional abortifacient: amounts larger than those found in food can make the uterus contract and may cause miscarriage, toxic doses near 5 g cause uterine bleeding, and doses near 10 g have induced abortion. The AHPA Botanical Safety Handbook lists Crocus sativus stigma among botanicals with potential abortifacient and uterine-stimulant action. Natural Medicines / NCCIH rate saffron likely unsafe in medicinal amounts during pregnancy. Culinary amounts used to flavor food are generally regarded as acceptable; supplemental or therapeutic doses should be avoided.
Insufficient data; avoid amounts above culinary. There is not enough reliable information on saffron during lactation. Culinary amounts in food are presumed acceptable, but supplemental or therapeutic doses should be avoided for want of safety data (Natural Medicines; NCCIH).
Culinary amounts, as a food flavoring, are considered acceptable. Medicinal or supplemental doses are not established as safe in children and should be avoided or used only under professional supervision. Keep concentrated extracts away from small children, since the toxic margin is narrow by body weight (Natural Medicines).
Saffron is safe and even healthful in culinary pinches (tens of milligrams) and in studied therapeutic doses up to about 1.5 g per day, but the margin narrows sharply above this. Doses near 5 g are toxic (vomiting, dizziness, uterine bleeding, thrombocytopenia and impaired clotting, and a yellow discoloration of skin and mucous membranes); about 10 g is abortifacient; and roughly 12 to 20 g can be fatal. It is a genuine uterine stimulant. It may trigger excitability or impulsive, manic behavior in people with bipolar disorder. Its brilliant, high-value color also makes it the single most adulterated spice, so the potency and identity of commercial product vary. Frame all medicinal use as practitioner-guided; do not self-dose above culinary amounts.
Pregnancy (uterine stimulant and abortifacient at medicinal doses); bleeding disorders and the two weeks before surgery (antiplatelet and blood-moving effect); concurrent anticoagulant or antiplatelet drugs; bipolar disorder (risk of inducing excitability or mania); known allergy to Crocus or the Iridaceae; and any dosing above culinary amounts without professional supervision.
Not a wild-collected at-risk species: Crocus sativus is a sterile triploid cultigen that exists only in cultivation, propagated by corms, so there is no wild-population pressure. The real stewardship issues are labor ethics (roughly 150 flowers hand-picked and hand-processed per gram of dried stigma) and rampant adulteration and fraud. Source certified, single-origin, lab-verified saffron (Iran, Kashmir, Spain, Afghanistan) from fair-labor suppliers, and reject cheap product likely cut with dyed safflower, turmeric, or marigold.
Song of Solomon 4:14 (KJV): 'Spikenard and saffron; calamus and cinnamon, with all trees of frankincense.' The Hebrew karkom (H3750), listed among the precious spices of the enclosed garden, is generally identified with Crocus sativus, and the English word crocus descends from karkom by way of Greek krokos. Also documented by Dioscorides (De Materia Medica, krokos) and long used in Persian, Greek, and Ayurvedic medicine as a perfume, dye, and medicine.
