Lungwort, also known as lungwort leaf or Pulmonaria officinalis, is a natural plant that has been used around the world for a variety of respiratory ailments, including coughs, colds, bronchial detoxification and catarrhal concerns. Lungwort is found in native damp habitats and coastal areas in Europe, Asia, North America, and Africa. Because it’s very sensitive to environmental toxins, the areas in which it is found are typically unpolluted old forests, and thus, the presence of lungwort is often a good indicator of an ecosystem's health. Lungwort herb powder is mostly used as an herbal tea for different health benefits. Simply steep the lungwort in hot water for up to 15 minutes, and you'll produce a bright, fragrant tea with a distinct aroma.
