Lungwort

Single herbal tincture made with dried leaf of Pulmonaria officinalis (Lungwort).
Lungwort, belonging to the genus Pulmonaria in the rough-leaved family (Boraginaceae), owes its botanical name to the Latin word 'pulmo', which means 'lung'. This is because of the similarity that was seen between the drawing on the leaves of the spotted lungwort and (diseased) human lungs. According to the signature theory, the plant was previously used as a remedy for lung diseases because of this similarity. The Dutch name 'pulmonary herb' is directly derived from the botanical name, and this name also occurs in several other Western European languages.
