Alpinia galangal, commonly known as galangal, has a long history of use in traditional medicine systems, especially in Southeast Asia and China, for managing respiratory conditions such as coughs, including dry cough. Traditional texts and ethnobotanical surveys document the use of galangal rhizomes in decoctions or teas intended to soothe the throat and alleviate cough symptoms. The plant is often described as having warming properties and is thought to help clear phlegm and relieve irritation in the respiratory tract.

From a scientific perspective, there are limited preclinical studies indicating that galangal extracts may have anti-inflammatory, antimicrobial, and mild bronchodilatory effects, which could theoretically contribute to cough relief. However, these findings are preliminary and mostly in vitro or in animal models, with no robust clinical trials specifically evaluating its effectiveness for dry cough in humans. The active compounds, such as galangin and other flavonoids, have been shown to modulate inflammatory pathways and may reduce throat irritation indirectly.

Despite the historical and anecdotal support for its use, modern clinical evidence is lacking, and the efficacy for dry cough remains unproven by rigorous scientific standards. Thus, the traditional use is acknowledged but should be approached with caution until more definitive research is available.
