Rating (out of 5): 2

Alpinia galangal, commonly known as galangal or greater galangal, is used in traditional medicine systems such as Traditional Chinese Medicine (TCM) and Ayurveda. In TCM, it is believed to have warming and dispersing properties, making it useful for conditions associated with "dampness" and cold, including certain types of coughs characterized by phlegm and a sensation of chest congestion. Traditional texts describe its ability to "transform phlegm" and "relieve coughing" by promoting circulation and dispelling dampness.

Scientific studies on Alpinia galangal primarily focus on its anti-inflammatory, antimicrobial, and antioxidant properties. Some in vitro and animal studies suggest that extracts from the rhizome may have mild expectorant and bronchodilatory effects, though these findings are preliminary and not directly linked to clinical outcomes for cough in humans. There are no large-scale, high-quality clinical trials specifically examining its efficacy for cough, especially in the context of "dampness" as described in TCM. Therefore, while its use for cough (damp) is well-rooted in traditional practice, scientific validation remains limited.

In summary, the use of Alpinia galangal for coughs associated with dampness is primarily justified by a long history of traditional use, with modest preliminary scientific support for its potential effects on respiratory symptoms. High-quality clinical research is needed to confirm its efficacy and safety in this context.
