Rhododendron groenlandicum
Circumpolar shrub used by First Nations peoples across Canada and Alaska as medicinal tea for coughs, colds, and digestive conditions.
Labrador Tea (Rhododendron groenlandicum) is a circumpolar shrub traditionally used by Indigenous peoples of Canada and Alaska for respiratory and digestive ailments. Its key active compounds include ledol, palustrol, germacrenol, ericolin, and flavonoids, which contribute to expectorant, antispasmodic, antimicrobial, and diuretic effects. Evidence is limited (Level C), and caution is required due to potential toxicity from concentrated preparations.
The terpenoids ledol and palustrol are believed to stimulate respiratory secretions via mild gastric irritation, triggering a reflex expectorant response. Flavonoids may exert antispasmodic effects by modulating calcium channels in smooth muscle, while antimicrobial activity likely involves disruption of bacterial cell membranes by essential oil components. The diuretic action may result from inhibition of renal tubular reabsorption, though specific receptor pathways remain uncharacterized.
