Sharp-leaf galangal (Alpinia galanga) is traditionally used in various Asian medical systems, such as Ayurveda and Traditional Chinese Medicine, for respiratory ailments including sinus congestion. Historical texts and ethnobotanical records describe its application as an expectorant and decongestant, often administered as decoctions or poultices for relief from nasal blockage, coughs, and other cold symptoms. The aromatic rhizome is believed to possess warming and stimulating properties, which are thought to help “open up” the sinuses and promote mucus drainage.

However, scientific validation of these effects is limited. While some laboratory studies have identified anti-inflammatory, antimicrobial, and mild bronchodilatory properties in extracts of Alpinia galanga, clinical trials specifically evaluating its efficacy for sinus congestion in humans are lacking. Most of the support for its use in sinus congestion therefore comes from long-standing traditional practice rather than robust clinical evidence. The overall quality and quantity of scientific data is insufficient to confirm its effectiveness for this indication, but its traditional usage persists in many cultures.
