Alpinia galanga, commonly known as galangal, has a long history of use in traditional medicine systems, particularly in Southeast Asia. For conditions like edema (swelling caused by fluid retention), galangal rhizome has been traditionally employed as a diuretic—a substance believed to promote urine production and thus reduce fluid accumulation in tissues. Traditional texts from Ayurveda and Thai medicine mention its use to relieve swelling and "water retention" in the body, often as a component of herbal mixtures rather than as a standalone remedy.

Scientifically, there is limited direct research evaluating galangal specifically for the treatment of edema in humans. Some animal studies and in vitro experiments suggest that extracts of Alpinia galanga may have mild diuretic effects, which could theoretically help in reducing edema. For instance, certain flavonoids and essential oils present in galangal have shown potential to influence kidney function and fluid balance in preliminary studies. However, the clinical significance of these findings remains unclear, and robust human trials are lacking.

In summary, while Alpinia galanga is traditionally used to support conditions like edema, and there is some weak preclinical evidence of diuretic activity, there is insufficient scientific validation to recommend it for this purpose based on current research. Thus, its use for edema is justified primarily by tradition rather than modern scientific evidence.
