Saffron has potent anti-inflammatory effects which are a big reason as to why it has performed so well in cell and animal studies as a cancer treatment; inflammation play key roles in cancer development.
Saffron contains safranal, crocin, and crocetin carotenoids that help to stop cancer from forming. These antioxidant plant pigments have been shown in animal and cells studies to inhibit triggers for the carcinogenic process, including free radical oxidative damage, viruses, environmental toxins, radiation, and inflammation. This is done by actively protecting cell DNA from damage and mutation stopping cancer from growing. Saffron extract when taken orally has been shown in animal studies to prevent tumors from forming prior to exposure to carcinogens.
