Black Raspberry
Rubus occidentalis
Black raspberries have shown exceptional results in human clinical trials for esophageal and colon cancer — reversing precancerous lesions through an epigenetic mechanism. Their anthocyanins, ellagic acid, and quercetin collectively inhibit NF-κB, induce apoptosis, and reduce angiogenesis. Black raspberries have among the highest concentrations of anti-cancer polyphenols of any food.
