Cancer Chemopreventive and Tumoricidal Properties of Saffron (Crocus sativus L.)

Abstract

Since cancer is the most common cause of death in the world population, the possibility that readily available natural substances from plants, vegetables, herbs, and spices may be beneficial in the prevention of cancer warrants closer examination. Saffron in filaments is the dried, dark red stigmata of Crocus sativus L. flowers and it is used as a spice, food colorant, and a drug in medicine.

This review discusses recent literature data and our results on the cancer chemopreventive activities of saffron and its main ingredients
