Bearberries are three species of dwarf shrubs in the genus Arctostaphylos, which are adapted to Arctic and sub-Arctic climates. They can be found growing in northern North America, Asia and Europe. The name bearberries derived from the edible fruits said to be consumed, but not enjoyed, by bears.

Arctostaphylos rubra (Red Bearberry), 10-30 cm tall, has red berries.

Bearberry has historically been used for medicinal purposes. It contain the glycoside arbutin, which has antimicrobial properties and acta as a mild diuretic. Bearberry is relatively safe, although large doses may cause nausea, green urine, bluish-grey skin, vomitting, fever, chills, severe back pain, and ringing in the ears.
