Saffron can prevent chemically induced skin carcinogenesis in Swiss albino mice.
One of the most promising strategies for cancer prevention today is chemoprevention using readily available natural substances from vegetables, fruits, herbs and spices. Among the spices, saffron (Crocus sativus, L) a member of the large family Iridaceae, has drawn attention because apart from its use as a flavouring agent, pharmacological studies have demonstrated many health promoting properties including radical scavenging, anti- mutagenic and immuno-modulating effects. In the present study the effects of an aqueous infusion of saffron on two stage skin papillogenesis / carcinogenesis in mice initiated by 7-12 dimethyl benz[a] anthracin (DMBA) and promoted with croton oil were investigated. Significant reduction in papilloma formation was found with saffron application in the pre-initiation and post-initiation periods, and particular when the agent was given both pre- and post-initiation. The inhibition appeared to be at least partly due on modulatory effects of saffron on some phase II detoxifying enzymes like glutathione-S-transferase (GST) and glutahinoe peroxidase (GPx), as well as catalase (CAT) and superoxide dismutase (SOD).
