Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Lesser Galangal (Alpinia officinarum) has a long history of use in traditional medicine systems, particularly in Southeast Asia, China, and Ayurveda. It has been employed for a variety of ailments, including digestive issues, respiratory conditions, and coughs. Traditional uses often involve preparing decoctions or powders of the rhizome for treating coughs, colds, and throat irritations. The rationale in these systems is based on the plant’s warming properties and its believed ability to clear phlegm and ease breathing. Scientifically, there is limited direct evidence supporting the use of Lesser Galangal specifically for cough. Some studies have identified anti-inflammatory, antimicrobial, and antioxidant compounds in the rhizome, which could theoretically contribute to symptom relief in respiratory conditions, but clinical trials targeting cough are lacking. The evidence for its use is therefore rooted primarily in traditional practices rather than modern clinical validation. Its rating reflects the strong traditional background but absence of robust scientific studies directly confirming its efficacy for cough.
