Rating (out of 5): 2

Galangal, a rhizome belonging to the Zingiberaceae family (which includes ginger), has a long history of use in traditional medicine systems such as Ayurveda and Traditional Chinese Medicine. Historically, both greater galangal (Alpinia galanga) and lesser galangal (Alpinia officinarum) have been employed as remedies for respiratory complaints, including bronchial congestion, coughs, and colds. The traditional rationale is based on galangal’s warming, aromatic, and expectorant properties, believed to help loosen phlegm and ease breathing.

While there is some laboratory evidence showing that galangal extracts possess anti-inflammatory and antimicrobial properties, high-quality clinical evidence in humans for its use specifically in bronchial congestion is lacking. Most of the support for galangal’s use in this context remains rooted in centuries-old practices rather than modern scientific validation. Consequently, while traditional use is well documented, the current scientific evidence base is inadequate to strongly support its efficacy for bronchial congestion.

In summary, galangal’s reputation as a remedy for bronchial congestion is grounded in traditional herbal medicine, with only limited and indirect support from preclinical studies. More rigorous clinical research would be needed to confirm its effectiveness for this indication.
