Human cultivation and use of saffron spans more than 3,500 years and extends across cultures, continents, and civilizations. Saffron, a spice derived from the dried stigmas of the saffron crocus, has through history remained among the world's most costly substances. With its bitter taste, hay-like fragrance, and slight metallic notes, the apocarotenoid-rich saffron has been used as a seasoning, fragrance, dye, and medicine.
Saffron crocus flowers, represented as small red tufts, are gathered by two women in a fragmentary Minoan fresco from the excavation of Akrotiri on the Aegean island of Santorini.
