What is the cranberry?
The cranberry is a small, bright-red berry from an evergreen shrub in the Ericaceae family.

Native to North America, it is particularly prized for its antioxidant properties and its potential for well-being, particularly in relation to urinary health.
Where does it come from?
Cranberries are mainly grown in the United States and Canada, where they thrive in damp, acidic bogs. It has been used for centuries by the indigenous peoples of North America for its medicinal virtues and as a source of food. With the boom in world trade, its cultivation has spread and consumption has become more democratic, particularly in Europe, where it is now recognized for its many benefits.
