Glucobrassicin is a known anti-cancer agent found in plants like broccoli and kale. Stefania Galetti, from the University of Bologna (English site here), has discovered that the compound has been identified in much larger quantities in a plant called Woad. Woad was used by ancient Brits and Celts to create the blue war paint that Mel Gibson made famous in Braveheart.

Hmmm, blueberries, Woad. It looks like anything blue is good. I like simple!
