Galangal
Galangal is a rhizome from Southeast Asia with a peppery, slightly medicinal flavor, used in cooking and traditional medicine. It contains volatile oils and phenolic compounds with modest anti-inflammatory properties in laboratory studies; human clinical evidence remains limited.
Also known as: blue ginger, laos, greater galangal, Alpinia galanga, Thai ginger

Galangal (Alpinia galanga) is a rhizome—underground stem—native to Southeast Asia, resembling ginger but with a sharper, more peppery, piney taste and white to off-white flesh with a pinkish-brown exterior skin. It is a staple in Thai, Indonesian, and Malaysian cuisines, appearing fresh, dried, or powdered in curries, soups, and beverages. Galangal is also used in herbal teas and traditional medicine systems across Southeast Asia and increasingly in Western wellness products.
Galangal is low in calories and macronutrients but contains volatile essential oils (notably 1,8-cineole and other terpenoids) and polyphenols including kaempferol derivatives and related flavonoids. These compounds have mild antioxidant and anti-inflammatory properties in laboratory and animal studies. Its effects on human digestion are modest; it may have a gentle carminative action (reducing gas), but no robust clinical evidence supports dramatic effects on gastric function or absorption.
Digestive and Anti-inflammatory Profile
Galangal has been used traditionally to address digestive discomfort and inflammation, and in vitro studies show its polyphenols have antioxidant activity. However, human clinical trials are limited. A small number of studies suggest galangal extracts may have modest anti-inflammatory effects, but evidence remains preliminary and is not sufficient to support medical claims. Whole galangal in culinary amounts contributes to overall polyphenol intake without known adverse digestive effects in most people.
Safety and Use Guidance
Galangal is recognized as safe for culinary use by food regulatory agencies and is not associated with common food allergens. It is not a significant source of high-FODMAP compounds and is well tolerated by most people. Individuals taking anticoagulants or with bleeding disorders should consult a healthcare provider before consuming large supplemental amounts, as some in vitro and animal evidence suggests potential blood-thinning properties. Culinary portions (less than 1 teaspoon dried per serving) pose no practical concern for the general population.
Frequently Asked Questions
Is galangal the same as ginger?
No. Galangal and ginger are both rhizomes but botanically distinct species. Galangal (Alpinia galanga) has a more peppery, piney flavor and different active compounds compared to ginger (Zingiber officinale). They are not interchangeable in all recipes, though both are used in Asian cooking and have been studied for potential anti-inflammatory properties in the laboratory.
Can galangal help with digestion?
Galangal is used traditionally for digestive comfort and may have gentle carminative properties, but rigorous human clinical evidence is limited. Culinary amounts are safe and well tolerated; if digestive symptoms persist, consult a healthcare provider for proper evaluation.
Are there any safety concerns with galangal supplements?
Culinary galangal is safe for most people. Those taking blood thinners or with bleeding disorders should consult a healthcare provider before taking large supplemental doses, as animal and in vitro studies suggest possible anticoagulant effects. Always inform your doctor about herbal supplements you use.
