Additional information:

Around one thousand kilograms of wild-harvested Greenland moss are required to make a kilo of Labrador Tea Oil (Ledum groenlandicum). It grows in peat bogs in out-of-the-way places and even well north of the snow line. This contributes to the power of its effects (Catty, 2001; p.33).

Another plant that shares the same Rhododendron genus as Ledum is Rhododendron anthopogon the flowers are distilled into an amazing essential oil. The oil has many benefits for calming the nervous system, it is excellent to strengthen the immune system, and helps to restore the adrenals during times of stress and fatigue.
