General Information:

Ledum palustre, is a low evergreen shrub growing to 50-60 cm in height. Interestingly, this shrub can generally survive fire as the rhizomes are found deep in the organic layer and it is often found in areas too wet to burn. Labrador tea is technically a flowering shrub with many erect branches, white flowers and distinctive evergreen leaves. It is one of the first plants to re-colonize after fire and grows rapidly. Leaves grow alternate, simple, evergreen, fragrant when crushed, and have a short-petiolate. Leaves are 10-40 mm long and 2-10 mm wide. They have a leathery-texture, are dull and dark green above, with the lower leaf surface densely covered in matted woolly hairs that turn from white to rusty-brown at maturity. The flowers are small, with a five-lobed white corolla, and produced several together in a corymb 3-5 cm in diameter. Numerous white flowers occur in showy rounded umbel-like terminal inflorescences. The flowers are hermaphrodite, have both male and female organs, one cm across; the calyx is small and five toothed; the corolla is composed of five white ovate to oblong petals, fused at the base. They emit strong smell to attract bees and other pollinating insects.

Walking through the flowering brush is an experience, not just for the abundant display of flowers but also for the heady aroma. Labrador tea’s aroma comes from essential oils such as ledol, palustrol and myrcene. These compounds repel cattle and large mammals, and can give sensitive people a headache. Despite its toxicity it has been cleverly used to flavor beer, instead of or alongside hops. The leaves are hung up in the clothes cupboard to repel insects. The branches are also placed among grain to keep mice away. A strong decoction of the leaves is used to kill lice and insects. The leaves contain tannin.

The plant is more strongly narcotic than Ledum latifolium and should not be used without expert supervision.

How to use:

Hot Infusion:

The basic method for dried herbs and flower is, take 2-3 tablespoons of dried herb in a cup or teapot. Pour hot water over it and cover it with lid for 10-30 minutes. Hot water is needed to draw out the antioxidants, enzymes, vitamins, flavonoids, and volatile oils from the botanicals. Strain and squeeze out as much as liquid as possible and enjoy!
