Chimaphila umbellata
Chimaphila umbellata, the umbellate wintergreen, pipsissewa, or prince's pine, is a small perennial flowering plant found in dry woodlands, or sandy soils. It is native throughout the cool temperate Northern Hemisphere. 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. Ecology. Although it has green leaves year-round, it receives a significant portion  of its nutrition from fungi in the soil (that is, it is a partial myco-heterotroph, which is not surprising as related plants, such as "Pyrola", are partial or full myco-heterotrophs). Taxonomy. There are four subspecies: Uses. Some 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). Name. "Pipsissewa" is a Cree name meaning "It-breaks-into-small-pieces".
