Anti-Cancer Studies: 

Of numerous berries or other natural products tested, aronia berry continues to show exceptional activity in fighting cancer. 
 Pilkington, Rooprai etc. all showed that aronia extracts introduced to highly malignant brain tumor lines slowed down regulation of MMP-9 activity and, when introduced, completely killed cancer cells within 24 hours.

In independent studies at University of Maryland, Cornell and Purdue aronia showed remarkable apoptosis in various cancer cell lines.

A 2004 animal-modeled study (Matsumoto et al) conducted at the Department of Food Science & Human Nutrition Faculty of Human Life Science at Fuji Women’s University, showed that the antioxidant effects of chokeberry extract had a “gastro protective” effect in treating acute gastric hemorrhagic lesions in rats, suggesting it might be an effective natural treatment for severe stomach problems in humans, including ulcers. A 2003 study (Malik et al) conducted at the Department of Nutrition and Food Science, University of Maryland, has provided preliminary indication of defense against colon cancer.
