In plants, ellagic acid is present in the form of ellagitannin, which is ellagic acid bound to a sugar molecule. It belongs to the family of phytonutrients called “tannins” and is viewed as being responsible for a good portion of the antioxidant activity of these fruits and nuts.
Ellagic acid is considered a potent antibacterial and antifungal, and it protects the liver. European medical studies also demonstrate that ellagic acid lowers the incidence of birth defects, promotes wound healing, and reduces heart disease. It has also shown positive attributes in esophageal, prostate, and colon cancer.
