Description
Galangal is a rhizome (underground stem) in the Zingiberaceae (ginger) family, closely related to ginger and turmeric. It looks similar to ginger but is generally larger, harder, and more cylindrical, with a pale, translucent skin and a woody, fibrous interior.
There are actually two plants commonly called "galangal": greater galangal (Alpinia galanga) and lesser galangal (Alpinia officinarum). Greater galangal is the more widely used in Southeast Asian cooking and is the variety most commonly referenced in recipes.
The flavor is sharp, peppery, and piney — distinctly different from ginger. It has notes of citrus, camphor, and black pepper, with a heat that is more aromatic than fiery. The texture is dense and woody, making it unsuitable to eat raw in chunks; it is typically sliced thin, pounded into pastes, or used as a flavoring that is removed before serving.
Galangal is a foundational ingredient in Thai, Indonesian, Malaysian, and Cambodian cuisines, and is increasingly recognized in global food culture for its unique flavor and medicinal properties.
Origin & History
Galangal is native to Southeast Asia, particularly Indonesia, Malaysia, and Thailand, where it has been cultivated and foraged for thousands of years. It grows in tropical lowland forests and is widely cultivated across the region.
In traditional medicine systems across Asia — including Ayurveda, Traditional Chinese Medicine (TCM), and Jamu (Indonesian herbal medicine) — galangal has been used for centuries as a digestive aid, anti-inflammatory, and respiratory remedy.
Galangal was one of the spices that reached Europe via ancient trade routes during the medieval period, where it was used in cooking and medicine. It fell out of favor in European cuisine but remained central to Southeast Asian food traditions.
In Sri Lanka, galangal (katusassara) is used in traditional Ayurvedic preparations and in certain regional curries, though it is less prominent than ginger or turmeric in everyday cooking.

Nutritional Benefits
Galangal is not typically consumed in large quantities (it's used as a flavoring rather than a main ingredient), but it contains several bioactive compounds:
- Galangin — a flavonoid with antioxidant and anti-inflammatory properties
- Alpinetin — a compound studied for potential anticancer activity
- 1,8-cineole — an aromatic compound also found in eucalyptus, with antimicrobial properties
- Dietary fiber — present in the rhizome
- Vitamins & minerals — contains small amounts of vitamin C, iron, and potassium
Note: Many health claims are based on traditional use or preliminary research. Clinical evidence for specific therapeutic effects is still developing.
How to Prepare Galangal
- Select: Choose firm, plump rhizomes with smooth, unbroken skin. Avoid any that are soft, shriveled, or moldy.
- Wash: Rinse under cold water to remove dirt. Scrub gently with a brush if needed.
- Peel (optional): The skin is very tough. For pastes, peel with a spoon or vegetable peeler. For slices used as flavoring (removed before serving), peeling is optional.
-
Slice or pound:
- For soups/broths: Cut into thin coins (3–5mm) — these will be removed before serving
- For pastes: Chop roughly and pound in a mortar and pestle (or blend) with other paste ingredients
- For curries: Mince finely or slice thin so it softens during cooking
- Cook: Add early in the cooking process to allow flavors to infuse. Galangal softens with prolonged cooking but remains fibrous — it is rarely eaten as a chunk.
