Woad a long-known dye plant and used by Celts and Britons as warpaint is rich in chemicals with anti-tumor properties, especially against breast cancer.
Italian researchers from the University of Bologna have found that Woad, a member of the cabbage family is rich in glucobrassicin, a compound that can act against cacenogenic compounds, particularly estrogen which is associated with a higher risk of breast cancer.
Glucobrassicin is also found in cabbage and broccoli. According to the research, Woad is apparently much richer in glucobrassicin than broccoli. Through “artificial wounding” the plant can be stimulated to significantly increase production of glucobrassicin as a defensive measure.
Because synthetic production is complicated and expensive, and the amounts of glucobrassicin in other vegetables are to small to harvest, the new reseach points to a way to produce enough of the compound for more research and possibly treatments.
One can only imagine the impact if it is found that the topical application of the Woad, a blue dye, is found to help fight breast cancer.
