Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Labrador Tea (Rhododendron groenlandicum or Ledum groenlandicum) has a history of traditional use among Indigenous peoples in North America, primarily as an herbal tea for a variety of ailments, including as a mild sedative to support sleep. Traditional accounts describe its use by Inuit, Cree, and other First Nations groups as a calming beverage, sometimes taken in the evening to promote relaxation. However, the evidence supporting its efficacy for insomnia is limited to these ethnobotanical and anecdotal reports.

There are no well-designed clinical studies or robust pharmacological investigations that validate Labrador Tea’s sedative or sleep-promoting effects in humans. Some phytochemical analyses reveal the presence of volatile oils (such as ledol and palustrol) and flavonoids, but their specific effects on sleep remain untested or poorly characterized. Furthermore, Labrador Tea can be toxic in large amounts, leading to symptoms like dizziness, nausea, or even paralysis, suggesting caution in its use.

In summary, while Labrador Tea is sometimes used traditionally for sleep support, there is scant scientific evidence to confirm its effectiveness or safety for insomnia. Its use for this purpose is based on cultural practices rather than on validated clinical research.
