Stillingia, also known as Stillingia sylvatica or "queen's root," has a history of use in traditional herbal medicine, particularly in North America. Historically, it was used by Native Americans and later by eclectic physicians in the 19th century as an expectorant and "blood purifier." Stillingia was included in early American pharmacopeias and recommended for respiratory complaints such as bronchitis, laryngitis, and chronic cough. The root was typically prepared as a decoction or tincture.

However, scientific evidence supporting the effectiveness of stillingia for lung or respiratory health is lacking. There are no well-conducted clinical trials or pharmacological studies confirming its benefits for the lungs. Some older reports suggest it contains irritant compounds that can stimulate the mucous membranes, but this could also produce adverse effects. Modern herbalists rarely use stillingia, and it is not included in contemporary evidence-based guidelines for respiratory support. Its use persists mainly in traditional or historical herbal references.

In summary, the justification for using stillingia to support the lungs is based on traditional practices rather than scientific validation, and the quality of evidence for its effectiveness is very low.
