Uses

For information only (typically historical) – I take no responsibility for adverse effects from the use of any plant.

No information directly for Pyrola grandiflora. However, the leaves of other Pyrolas (wintergreens) have been moistened to be used to counter skin irritation and have been used to treat mouth or throat inflammation.

Identification

The largeflowered wintergreen (Pyrola grandiflora) is a perennial subshrub with evergreen leaves. The wintergreen family is named such because of the evergreen leaves. Plants grow from a small rhizomatous taproot. The rounded leaves are mostly basal, and petiole on an often pinkish stem. Leaves are somewhat waxy and dark green. The stem is pink or red and 6-25 cm (2-10 in) tall. It has one inflorescence per stem with a 4-12 flowered raceme. The flowers have 5 creamy white petals with pink veins and about 10 stamens with yellow anthers and a single stigma per ovary. The fruit is pink or red when immature and black or brown when mature.
