Note: Saffron (Crocus sativus) should not be confused with meadow saffron, also known as autumn crocus (Colchicumautumnale L.), which is a poisonous plant. Saffron grown in America or Africa has been referred to as American saffron and African saffron, respectively, which is a misnomer, as Carthamus tinctorius is the real American saffron and Lyperia crocea Ecklon is the real African saffron. Saffron should also not be confused with prairie crocus (Anemone patens).

Background

Saffron is the dried stigma of the crocus (Crocus sativus) flower. It is available both as filaments and powder. Around 75,000 blossoms are needed to make a single pound of saffron. For this reason, the price of saffron can range from $50 to $300 per ounce.
Saffron has a long history of use as a spice, medicine, and yellow dye. The crocus was reportedly used by ancient Greek and Roman civilizations and in medieval Egypt.
Saffron may have anticancer, antidepressant, nerve protective, and antioxidant properties and may have effects on the immune system. Saffron has also been studied for its ability to improve symptoms of Alzheimer's disease, asthma, infertility, menstrual problems, and psoriasis.

Patients taking insulin or drugs for diabetes by mouth should be monitored closely by a qualified healthcare professional, including a pharmacist. Medication adjustments may be necessary.
Saffron may increase the risk of bleeding when taken with drugs that increase the risk of bleeding. Some examples include aspirin, anticoagulants (blood thinners) such as warfarin (Coumadin?) or heparin, antiplatelet drugs such as clopidogrel (Plavix?), and nonsteroidal anti-inflammatory drugs such as ibuprofen (Motrin?, Advil?) or naproxen (Naprosyn?, Aleve?).
Saffron may cause low blood pressure. Caution is advised in patients taking drugs that lower blood pressure.
Saffron may increase the amount of drowsiness caused by some drugs. Examples include benzodiazepines such as lorazepam (Ativan?) or diazepam (Valium?), barbiturates such as phenobarbital, narcotics such as codeine, some antidepressants, and alcohol. Caution is advised while driving or operating machinery.
Saffron may also interact with Alzheimer's agents, antianxiety drugs, antiasthma drugs, anticancer drugs, antidepressants, antihistamines, anti-inflammatory agents, antiseizure drugs, cardiovascular agents, cholesterol-lowering drugs, cisplatin, cough medications, cyclophosphamide, drugs that may affect the nervous system, drugs that may damage the kidney, drugs that may damage the liver, fertility agents, gastrointestinal agents, gemcitabine, hypnotic agents, immune suppressants, impotence agents, mitomycin C, noradrenaline, opiates, painkillers, pentylenetetrazol, scopolamine, and urethane.
