Galangal, which refers to several species in the Zingiberaceae family (such as Alpinia galanga and Kaempferia galanga), has a long history of use in traditional medicine systems across Asia. In traditional Chinese medicine, Ayurveda, and Southeast Asian herbal practices, galangal rhizomes are often used to relieve symptoms associated with respiratory conditions, including lung congestion, cough, and bronchitis. The use is typically based on galangal's warming properties, believed to help "disperse cold" and "move qi" in the body, which in traditional frameworks are associated with relieving phlegm and congestion in the lungs.

From a scientific perspective, evidence supporting galangal specifically for lung congestion is limited. Some laboratory studies have shown that galangal contains compounds with anti-inflammatory and antimicrobial properties, and there are a few animal studies suggesting potential bronchodilatory effects. However, these findings are preliminary and do not directly validate its efficacy for treating human lung congestion. To date, there are no robust clinical trials confirming its effectiveness for this specific use. Thus, while the traditional rationale for using galangal to support lung function is well established, scientific validation remains weak, and more research is necessary to confirm these traditional uses.
