Labrador Tea
Rhododendron groenlandicum
This plant is kept in the atlas for identification and safety, not for use. Read the safety notes below before handling it, and keep it away from children, cats, and food.
For countless generations, Inuit, Cree, Ojibwe, and other Indigenous peoples across the circumpolar north gathered the narrow, curled leaves of this low bog shrub to brew a warming tea against the deep cold. It was traditionally sipped for colds, coughs, sore throats, and unsettled stomachs, and the leaves were sometimes made into a poultice for skin troubles. When Hudson's Bay Company traders and northern settlers ran short of imported black tea, they turned to this plant instead, which is how it earned the name Hudson's Bay tea and became a fixture of trapper cabins and northern kitchens alike.
Safety.
Brewed strong or drunk in quantity, Labrador tea is toxic and has caused nausea, cramping, and drowsiness, so it should only be brewed weak and enjoyed occasionally. It grows alongside poisonous bog-rosemary, a dangerous look-alike, so correct identification is essential before foraging.
Our sister app HerbLens identifies labrador tea from a photo and keeps its full botanical portrait: growing guide, harvest notes, and look-alike warnings.
