Blueberries have been an integral part of herbal medicine since the Middle Ages. The small shrub belongs to the heather family (Ericaceae), which grows in cool and temperate climates. In common parlance, the berry is also known as blueberry or huckleberry.
In the case of the wild blueberry, not only the skin but also the pulp is blue in color, while in the so-called cultivated blueberry the dye is only found in the skin.
