Lungwort (Pulmonaria officinalis) has a long history of traditional use for respiratory conditions, including laryngitis. Its name and historical application stem from the "doctrine of signatures," an old belief suggesting that plants resembling certain body organs could be used to treat ailments of those organs. Because the spotted leaves of lungwort were thought to resemble diseased lungs, it was used in folk medicine for coughs, bronchitis, and throat inflammation, including laryngitis. Herbalists used lungwort preparations (teas, extracts, syrups) to soothe mucous membranes and reduce irritation in the throat and airways. However, there is minimal scientific research specifically evaluating lungwort’s efficacy for laryngitis. Available evidence is limited to its traditional use and some in vitro studies indicating potential anti-inflammatory or mild antimicrobial effects, but these do not directly address laryngitis in humans. No robust clinical trials or systematic reviews confirm its effectiveness for this condition. Therefore, while lungwort is still found in some herbal remedies for throat and respiratory issues, its use for laryngitis is justified primarily by tradition rather than scientific validation.
