If you’ve ever wandered through the forests of the Northern Hemisphere, you might have come across small, glossy red berries growing close to the ground. These are bearberries—a fruit that not only delights wildlife like bears (hence the name) but also carries a long history of medicinal and nutritional value for humans.
For centuries, Indigenous peoples in North America and Europe have used bearberries for health purposes, especially for urinary tract health and as a natural antiseptic.

Bearberries have been a staple in folk remedies for centuries, particularly among Native American tribes who used them to treat urinary tract infections, kidney problems, and inflammation. The berries and leaves are also used in teas, tinctures, and natural supplements.
