Teaberry refers to the fruit of the Gaultheria procumbens plant, commonly known as the eastern teaberry or checkerberry. This small, red berry grows in wooded areas of North America and is known for its sweet, minty flavor. The plant is a low-growing evergreen shrub, and its leaves are often used to make a tea-like beverage. In addition to its culinary uses, teaberry is also valued for its essential oils, which are extracted from the leaves. These oils have been used in traditional medicine and are sometimes found in products like toothpaste and gum for their flavor and potential health benefits.
