Labrador tea is a flowering shrub also known as St. James tea, Indian tea and Hudson Bay tea. Its botanical name is Ledum latifolium. Labrador tea is native to Greenland and Canada, specifically Nova Scotia and the Hudson Bay and Labrador regions. As an evergreen plant, Labrador tea grows between 4 and 5 feet tall. It has irregular, woody branches that produce long, oblong-shaped leaves. The leaves are distinguishable by their rolled edges that have a smooth upper side and textured underside. During the summer, the Labrador tea shrub produces large, white flower clusters.1 First Nations and aboriginal tribes used Labrador tea leaves for medicinal purposes. The leaves were used both fresh and dried and were boiled to create a tea that was consumed hot. The Labrador tea leaf drink produces a tonic with a spicy taste and aromatic scent.1 2
