Marsh Labrador tea is made from the leaves of a small, evergreen shrub called Rhododendron tomentosum. It's traditionally used as medicine.
Marsh Labrador tea contains high amounts of essential oils, which include various chemicals. Some of these chemicals can affect the nervous system and cause an abortion.
People sometimes use marsh Labrador tea for back pain, insect bites, osteoarthritis, and many other conditions, but there is no good scientific evidence to support these uses. Using marsh Labrador tea can also be unsafe.
Don't confuse marsh Labrador tea with bog Labrador tea. These are not the same.
