Lungwort

Christopher Hobbs:

“Lungwort is both expectorant and emollient, so it is useful for bronchitis and laryngitis. This lichen is often found as one of the ingredients in tea blends for coughs and may be safely given to children. Because of the lichen acids it contains, such as usnic acid, it has powerful antibacterial properties, especially against strep, staph, bacteria, and the organisms that are associated with tuberculosis and bacterial pneumonia.

Lungwort has a taste of BITTER and a temperature of COOL.”

Historical Uses

Lungwort (Pulmonaria officinalis) has a history of use dating back to medieval Europe, where herbalists applied the Doctrine of Signatures—a belief that plants resembling human organs could be used to treat ailments of those organs. Because its leaves are spotted and resemble lung tissue, lungwort was used to treat respiratory issues, such as coughs, bronchitis, and tuberculosis.

Modern Clinical Uses

Today, herbalists and naturopaths still use lungwort for its purported benefits in respiratory health. It’s believed to act as a mild expectorant, anti-inflammatory, and demulcent, helping to soothe irritated mucous membranes and thin mucus in the respiratory tract. Some also recommend it for sore throats, digestive support, and wound healing.

Chemistry

Lungwort contains various bioactive compounds, including flavonoids, tannins, saponins, and allantoin. Flavonoids, such as quercetin and kaempferol, are known for their antioxidant properties, while allantoin is used for its wound-healing effects. The saponins in lungwort may account for its ability to loosen mucus.

Pharmacology

The plant’s anti-inflammatory effects are attributed to its antioxidant flavonoids, which can help reduce oxidative stress in respiratory tissues. The mucilage (gel-like substances) in lungwort may create a protective barrier over mucous membranes, reducing irritation in the respiratory tract.

Clinical Trials

Few clinical trials have been conducted specifically on lungwort, and much of the evidence supporting its effectiveness remains anecdotal. Limited laboratory studies indicate antioxidant activity, but more robust clinical data are needed to establish its efficacy in treating respiratory or other ailments.

Summary

Lungwort has a long history as a traditional remedy for respiratory ailments. Modern herbalists value it for its potential expectorant and soothing effects on respiratory tissues, largely due to flavonoids and mucilage content. While generally safe in moderate use, clinical data on its efficacy and safety are limited.
