Rating (out of 5): 2

Lesser Galangal (Alpinia officinarum) has a long history of use in traditional medicine systems, particularly in Ayurveda, Traditional Chinese Medicine, and Southeast Asian folk remedies. It has been employed for various respiratory ailments, including coughs, especially those characterized as "spastic" or associated with bronchospasm. The traditional rationale is based on galangal's warming, aromatic, and expectorant properties, believed to help clear phlegm and ease airway constriction. Several classic herbal texts mention its use for cough and throat discomfort, though typically not as a primary remedy.

From a scientific standpoint, there is limited direct research on Lesser Galangal’s effects on cough. Some in vitro and animal studies suggest antitussive and anti-inflammatory effects of galangal extracts, possibly due to compounds like galangin and other flavonoids, which may modulate bronchial responses or reduce irritation. However, these studies are preliminary, and clinical trials in humans specifically for spastic cough are lacking.

In summary, the use of Lesser Galangal for spastic cough is primarily justified by traditional usage. While there are some promising pharmacological indications from preclinical research, robust scientific evidence in humans is absent. Thus, its use for this condition is considered to have a traditional basis with limited scientific support (rated 2/5).
