Native to temperate areas of Europe and now naturalized in the Americas and Australia, growing along roads, in open areas, and woodlands. The plant is a sprawling, prickly shrub, growing to twelve feet having palm-shaped leaves with three to five lobes, white to pale pink flowers, and clusters of large, black berries that contain numerous edible, but crunchy, seeds.


In the 1st century CE, Dioscorides recommended blackberries in a gargle for sore throats, a practice that remains today.

In European folk medicine, the leaves have long been used for washing and staunching the bleeding of wounds.

In parts of England, arching blackberry runners that had rooted at both ends were credited with magical properties. Children with hernias were pushed under these arches for a magical cure.

The Kiowa-Apache, Cherokee, Chippewa, Ojibwa, Menominee, Delaware, and Iroquois all have used decoctions to treat diarrhea. The Chippewa used a tea to treat lung conditions. The Cherokee found that the root made an effective topical wash to relieve the discomfort of hemorrhoids.
