Sweetgum (Liquidambar styraciflua) has a history of traditional use in North American folk medicine, particularly among Native American groups and early settlers. The tree's resin, known as storax or liquidambar, has been used in various forms—such as teas, syrups, or topical applications—for its supposed expectorant and soothing effects on respiratory conditions, including bronchitis. The rationale behind its use lies in the aromatic and resinous compounds found in sweetgum, which are thought to possess mild antimicrobial and anti-inflammatory properties.

However, scientific evidence supporting sweetgum’s effectiveness for bronchitis is limited. Most available data are anecdotal or based on traditional practices rather than clinical trials. Some laboratory studies have identified compounds in sweetgum, such as cinnamic acid derivatives and shikimic acid, with potential antiviral and antibacterial activity, but these findings do not directly translate to proven benefits for bronchitis in humans. As a result, while sweetgum continues to be used in herbal and folk remedies, its efficacy for bronchitis is primarily justified by tradition rather than robust scientific validation.

In summary, sweetgum's use for bronchitis is rooted in historical and ethnobotanical practices, with a modest level of supporting evidence (rated 2/5) due to the lack of controlled clinical studies. Individuals interested in using sweetgum should consult healthcare professionals, especially since safety and efficacy are not well established.
