WINTERGREEN LEAVES, Gaultheria procumbens. While many people confuse wintergreen with mint, they are not related in any way. Wintergreen has long been used as an herbal remedy for arthritis, swollen joints and sore muscles. It goes by many names: teaberry, checkerberry, dearberry, spiceberry, boxberry, and even a tea party. The latter refers to its use during the American Revolution as a substitute for heavily taxed British tea.
