Lobaria pulmonaria
Lichen growing on old forest trees used by Native Americans and European herbalists as an expectorant and lung herb by Doctrine of Signatures.
Lungwort Lichen (Lobaria pulmonaria) is a lichen traditionally used for respiratory conditions and externally for wound healing. Its primary active compounds include usnic acid, stictic acid, and norstictic acid, which contribute to its expectorant, antimicrobial, and anti-inflammatory properties. Evidence is limited (Level C), with most data derived from in vitro and traditional use.
Usnic acid exhibits antimicrobial activity by disrupting bacterial cell membranes and inhibiting RNA synthesis, while stictic and norstictic acids demonstrate anti-inflammatory effects via inhibition of cyclooxygenase-2 (COX-2) and nuclear factor-kappa B (NF-κB) pathways. The expectorant action is thought to arise from mild irritation of bronchial mucosa, stimulating mucociliary clearance. Additionally, usnic acid may promote wound healing through enhanced fibroblast proliferation and collagen deposition.
