Saffron, also known as Kesar, is cultivated in many countries including France, Turkey,
Iran and India. It is popularly used as a food coloring and flavoring agent. The
plant derived spice is made from the dried stigmas of the flowers of Crocus
sativus.
In folk and modern medicine, saffron has been used to treat depression, asthma, premenstrual syndrome, erectile dysfunction, macular degeneration and Alzheimer’s disease and insomnia. Experimental studies have revealed the role of saffron extracts and its components as cancer therapeutic agents as well.

Scientists have been able to identify various
compounds in saffron that have anti-carcinogenic and anti-mutagenic properties.
This has also been found that saffron can even delay certain types of tumor
growth. Although the research is still in their early stages, but the broad
range of activities of the plant extract on cancer cells encourages tapping the
benefits of saffron in negating cancer.
Saffron has been shown to
inhibit carcinogen-induced skin carcinoma in mice and to have cytotoxic action
against human leukemia cell lines. Saffron also has been shown to cause cell
death in liver cancer cells and carcinoma cells.
Saffron extract and its
constituent, Crocin, have shown to
significantly inhibit the growth of cancer cells while not ameliorating the
normal cells. Crocetin, another
natural carotenoid constituent of saffron, has shown significant potential as
an anti-tumor agent in animal models and cell culture systems by enhancing
anti-oxidative system, inhibiting nucleic acid synthesis, inducing apoptosis
and hindering the growth factor signaling pathways.
Saffron
extract has been shown to have dose-dependent inhibitory effects on the
proliferation of human breast cancer cells. It has been proved to greatly
inhibit chemotherapy-induced cellular DNA damage. It also was
successful in delaying and preventing cancer in mice that were genetically
predisposed to both soft tissue sarcoma and squamous cell carcinoma. Topical
application of saffron also resulted in the inhibition of skin tumors. Even
more recent research has revealed that saffron can also be utilized to help
reduce side effects of chemotherapy drugs.
The other compounds
of interest found in saffron are safranal,
picrocrocin, and β-carotene
that have also shown to have antioxidant, anti-inflammatory,
radioprotective and anti-carcinogenic properties. In different cancers,
it has been established that saffron extracts are dose dependent, and also
dependent on the method of intake. Further studies are required to evaluate the
safety and efficacy of saffron in cancer treatment.
