It grows 10–35 cm tall, and has
evergreen shiny, bright green, toothed leaves arranged in opposite pairs or whorls of 3–4 along the stem. Leaves have a shallowly toothed margin, where the teeth have fine hairs at their ends. The
flowers are white or pink, produced in a small
umbel of 4–8 together.

Plateau Indian tribes used a boil of prince's pine to treat
tuberculosis.
The twentieth century
Appalachian folk healer Clarence "Catfish" Gray, "Man of the Woods", credited pipsissewa with curing his own heart problems and included it in his 15 herb cure-all "bitters."
It is used as a flavoring in candy and soft drinks, particularly
root beer.
The roots and leaves of ''Chimaphila umbellata'' can be boiled to create tea.
Recent investigations show the anti-proliferative effect of ''Chimaphila umbellata'' in human breast cancer cells (MCF-7).
