Saffron (Crocus sativus) is a small flowering crocus with purple petals and three deep-red stigmas per flower, which are hand-harvested and dried to become the spice — a labor-intensive process that makes it one of the most expensive spices by weight in the world.

Is Saffron safe to use?
Ordinary culinary amounts (a pinch or a few threads) are considered safe, including in most traditions during pregnancy from the second trimester onward. However, saffron in concentrated or supplement-strength doses is a genuine pregnancy concern — amounts above roughly 5g have documented uterine-stimulant and abortifacient effects, and even smaller concentrated doses have been linked to abnormal uterine bleeding in a clinical study. Avoid saffron supplements and concentrated extracts entirely during the first trimester, and limit to trace culinary amounts throughout pregnancy. It may interact with antidepressants, blood thinners, blood pressure medication, and diabetes medications at concentrated doses — those on any of these should talk with a healthcare provider before taking saffron beyond ordinary cooking amounts. Stop concentrated use at least 2 weeks before surgery. Given how commonly saffron is adulterated, verified purity matters more here than with most herbs — an unknown adulterant carries its own unknown risk profile.
