Plant
Striped wintergreen
Chimaphila maculata
Also known as: spotted wintergreen, pipsissewa, rheumatism root
A small evergreen perennial of dry oak and oak-pine forest understories across the eastern United States. 4–10 inches tall; whorled leathery leaves with a striking white midvein stripe; nodding pinkish-white flowers in early summer. A traditional Indigenous and Appalachian medicinal plant — *pipsissewa* derives from the Cree word for the related *Chimaphila umbellata*, meaning 'it breaks into small pieces' (a reference to the plant's traditional use in dissolving kidney stones). In the Hudson Highlands the species is one of the most consistent indicators of mature, undisturbed oak-heath forest understory.
Scientific
Chimaphila maculata is in the Ericaceae (heath family). Evergreen, with 2–4 cm leathery leaves arranged in opposing whorls along a short stem; the leaves carry a distinctive white midvein-and-major-vein stripe pattern that gives the plant its common name. Flowers nod from a 4–10 inch stem in late June and July — five waxy white-to-pink petals around a central ring of purple anthers. Fruits are small upright capsules that persist through winter.
The plant is a partial mycoheterotroph — its roots associate with ectomycorrhizal fungi that also partner with surrounding oaks, allowing the plant to receive some carbon and nutrients indirectly from the canopy trees through the shared fungal network. This dependence on a mature mycorrhizal community is part of why the species disappears from disturbed forest and recolonizes only slowly. The plant is therefore a useful indicator of mature, undisturbed forest understory — its presence implies decades of undisturbed mycorrhizal substrate beneath the leaf litter.
Medicinal
In Indigenous (Cree, Ojibwe, Mohegan, Cherokee) and Appalachian traditional medicine, Chimaphila species have been used as diuretic and anti-inflammatory remedies, especially for urinary tract complaints — the related Chimaphila umbellata (pipsissewa) was the more commonly-used species but C. maculata shares much of the same pharmacology. The plant contains arbutin (the same urinary-tract-active compound found in bearberry and many heath-family plants) and several flavonoids and quinones with documented anti-inflammatory activity.
Traditional preparation is a tea or tincture of the leaves; the plant should not be wild-harvested today as populations are slow to recolonize and the species is locally uncommon enough to be vulnerable to overharvest.
Cultural
The name pipsissewa comes through English from the Cree pipsisikweu — “it breaks (a stone) into small pieces” — referring to the plant’s traditional use against kidney and bladder stones. The species was a regular ingredient in 19th-century American patent medicines and root beers (alongside [[sassafras|sassafras]] and birch); the plant’s commercial harvest in that period contributed to its current scarcity in many parts of the eastern U.S.
