Small blackthorn berries, bluish in color, grow in bushes alongside the edges of forests, riverbanks, pastures and rugged terrain.

The blackthorn fruit, which has a very bitter and sour taste, is rich in vitamin C, tannins, organic acids, and fructose. It therefore has a beneficial effect on the digestive organs. The most common use is for jam, which is recommended for people who suffer from digestive problems since it reduces stomach pain and speeds up digestion.
