Lungwort (Pulmonaria officinalis) has been used in traditional herbal medicine for centuries, primarily in Europe, as a remedy to support the respiratory system, including the bronchi and lungs. The name "lungwort" itself stems from the "Doctrine of Signatures," a historical concept where the appearance of a plant was thought to indicate its therapeutic use; lungwort’s spotted leaves were seen as resembling diseased lungs, leading to its use in treating pulmonary conditions. Traditional uses include decoctions or teas made from the leaves to soothe coughs, mild bronchial irritation, and other respiratory complaints.

However, scientific evidence supporting the efficacy of lungwort for bronchial or respiratory support is limited. While the plant contains compounds such as mucilage (which can soothe irritated mucous membranes), saponins, flavonoids, and small amounts of antioxidants, high-quality clinical studies are lacking. Most available data are based on in vitro studies or animal models, and there are no robust, peer-reviewed human trials demonstrating clear benefits for bronchial health. A few phytochemical analyses suggest mild anti-inflammatory or antimicrobial activity, but these findings have not been translated into clinical recommendations.

In summary, lungwort’s use for bronchial support is primarily rooted in traditional herbalism, and while there are plausible mechanisms for mild symptomatic relief, scientific validation remains insufficient at this time.
