Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Labrador Tea (Rhododendron groenlandicum, formerly Ledum groenlandicum) has a longstanding history of use among Indigenous peoples of North America, particularly in Canada and Alaska. Traditionally, the leaves were brewed into a tea and consumed to help alleviate symptoms of respiratory illnesses, including bronchial congestion, coughs, and colds. The practice was adopted by early European settlers as well. Ethnobotanical records and oral histories document its use as an expectorant and to ease breathing difficulties, suggesting that its aromatic compounds might help open airways or soothe mucous membranes.

However, while traditional use is well established, scientific evidence to support the efficacy and safety of Labrador Tea for bronchial congestion is limited. Few, if any, rigorous clinical trials have been conducted. Laboratory analyses have identified terpenoids and essential oils in the plant, which could theoretically have mild anti-inflammatory or soothing effects, but direct evidence for clinical benefit is lacking. Additionally, Labrador Tea contains compounds (like ledol) that can be toxic in high amounts, raising safety concerns with frequent or high-dose use. In summary, while historical and traditional uses for bronchial congestion are well documented, scientific validation is minimal, and caution is advised.
