From the Manufacturer's Label:
One of the most potent antioxidants ever discovered, pine bark from the Eastern White Pine, Pinus massoniana, contains complex plant compounds known as proanthocyanidins. Proanthocyanidins are condensed tannins that are responsible for the astringent character of fruits, berries, beans, and tea. These bioflavonoids are powerful antioxidants, giving benefits to the cardiovascular system and capillary health. They are potent, free radical scavengers that help the body reduce oxidative damage.**
