Anthocyanidins may prevent blood platelets from clumping together, which minimizes the risk of blood clots (associated with heart attack and stroke). Bilberry fruit contains tannins, a substance that acts as an astringent, stopping bleeding. The tannins and anthocyanidins may equalize each other when the whole bilberry fruit is used for medicinal purposes. Anthocyanidins increase rhodopsin production, a pigment that assists the eye'
