Rating (out of 5): 2

Galangal, a rhizome related to ginger and commonly used in Southeast Asian cuisine, has a longstanding history in traditional medicine, particularly in Ayurvedic and traditional Chinese medicine. It has been used to alleviate digestive complaints, including acid indigestion, dyspepsia, stomach pain, and bloating. Historical texts and folk practices cite galangal's warming, carminative, and stimulant properties as beneficial for promoting digestion and reducing discomfort from excess stomach acid or slow digestion.

However, the scientific evidence supporting galangal’s efficacy for acid indigestion is limited. While a few in vitro and animal studies have explored galangal’s gastroprotective effects—such as anti-inflammatory and antioxidant activity that could, in theory, protect gastric mucosa—there is a lack of robust clinical trials in humans that directly assess its effectiveness for acid indigestion. Most modern herbal references cite traditional use as the basis for recommending galangal in this context, rather than rigorous scientific validation.

In summary, galangal’s use for acid indigestion is primarily justified by traditional practices, with only modest preclinical evidence and little direct clinical validation. Individuals with acid indigestion should consult healthcare professionals before using galangal as a remedy, especially if they have underlying health conditions or are taking medications.
