Galangal, a rhizome related to ginger and commonly used in Southeast Asian cuisine and traditional medicine, has a long history of use for respiratory ailments such as bronchitis. In Ayurvedic and traditional Chinese medicine, both Alpinia galanga (greater galangal) and Alpinia officinarum (lesser galangal) have been employed as remedies for coughs, sore throat, and bronchial congestion. The rationale is often attributed to galangal's warming properties and its ability to stimulate expectoration, thereby helping clear mucus from the respiratory tract.

However, scientific research on galangal for bronchitis specifically is limited. While some in vitro and animal studies suggest that galangal extracts possess anti-inflammatory, antimicrobial, and antioxidant activities, direct clinical evidence supporting its efficacy in bronchitis is lacking. The essential oils and bioactive compounds (such as galangin and eugenol) may theoretically aid in reducing inflammation or microbial load in the airways, but these effects have not been robustly demonstrated in human trials for bronchitis treatment.

In summary, the use of galangal for bronchitis is rooted in traditional medical practice, with modest pharmacological evidence suggesting potential benefits, but without strong scientific validation from controlled clinical studies.
