Galangal: What It Is, How It Tastes and How It’s Used

Galangal looks like a paler, harder, more fibrous ginger, but it tastes sharper, more peppery and more resinous. It’s the rhizome of Alpinia galanga, a member of the ginger family, and a staple of Southeast Asian cooking, from Thai tom kha kai to curry pastes. It was well known in medieval England, too: the Cook in Chaucer’s Canterbury Tales seasons with “galyngale.” Two species get sold under the name, and powdered galangal is sometimes cut with the lesser one.

At a glance

Greater and lesser galangal

Two species get sold as galangal, and trade data often lump them together.¹

• Greater galangal (Alpinia galanga) is the one most cooks mean. Kew gives its native range as southern China to western and central Malesia, covering Assam, Bangladesh, Myanmar, Thailand, Cambodia, Vietnam, southern China, Hainan, peninsular Malaysia, Sumatra, Java, Borneo and the Philippines, with introduced populations in India, Sri Lanka and Taiwan.
• Lesser galangal (Alpinia officinarum) is native to southeastern China, Hainan and Vietnam. Its rhizomes are smaller and dark brown to black, on a plant only about 1–1.5 m tall.

Other members of the ginger family have their own profiles: see sand ginger and fingerroot.

Flavor and the compounds behind it

Greater galangal has a strong pungent taste like a mix of black pepper and ginger. It’s similar to ginger but with notes of citrus, pepper and pine. Fresh galangal smells sharp and almost camphor-like, with less of ginger’s sweet, rounded heat.

The essential oil makes up 0.2–1.5% of the dried rhizome. Studies from the 1980s confirmed 1,8-cineole as its main component; older literature had also reported camphor, cineole (20–30%) and methyl cinnamate (48%).¹ The older and newer figures come from different samples and methods, so don’t combine them. PROSEA also names 1’-acetoxychavicol acetate as a component of fresh and newly dried rhizomes, and galangin, a compound that can dye wool yellow.

None of the sources we reviewed compares the flavor of greater and lesser galangal directly, so we can’t tell you which is stronger.

Origin and history

PROSEA says galangal’s exact origin is unknown, and the oldest reports of its use come from southern China and Java. Today it’s grown, and found semi-wild near villages, across Southeast Asia, mostly in home gardens.¹

Galangal was well known in medieval England. In the General Prologue to Chaucer’s Canterbury Tales, the Cook’s seasonings include “galyngale,” glossed by Harvard’s Chaucer site as galingale, a spice.² PROSEA also records that Arabs used the rhizome as an aphrodisiac.¹

Plenty of stories about galangal’s history get passed around without a traceable source: that the name comes from an Arabic word meaning “mild ginger,” that Arabs brought it to Europe in the 9th century, that Hildegard of Bingen called it the “spice of life,” and that it wasn’t botanically classified until the late 19th century. We couldn’t confirm any of them, so we don’t present them as fact.

Production and trade

PROSEA says data on galangal production, consumption and trade are scarce and unreliable, partly because greater and lesser galangal often aren’t told apart. It names Thailand, Indonesia and India as the main suppliers and reports that the Netherlands imports at least 100 tonnes of fresh rhizomes and 25–30 tonnes of dried rhizomes a year.¹ PROSEA doesn’t give a year for those import figures, and we found no current official production statistics for galangal.

How galangal is used

Galangal is said to be indispensable in everyday cooking throughout South and Southeast Asia, and the flowers and young shoots are eaten as a vegetable or spice. It’s widely used in the cooking of the Indian subcontinent and Southeast Asia.

• Thailand. Kha is the Thai name for galangal, as in tom kha kai, chicken soup with coconut milk. A Northern Illinois University recipe simmers sliced young galangal with coconut milk, lemongrass and kaffir lime leaves before adding the chicken, fish sauce and lime juice.³
• Indonesia and Malaysia. It’s known as lengkuas, and in Java as laos.

In the kitchen

Fresh galangal is much harder than ginger, so it usually gets sliced into thin coins for soups and broths, or pounded or blended into curry pastes, not grated. The slices are tough, and people often leave them on the plate. It goes naturally with lemongrass, kaffir lime leaves, chiles, shallots and coconut milk.

The rhizomes are sold fresh or dried, and the dried product is usually ground before use. Fresh and dried galangal don’t taste the same; see dried vs. fresh galangal.

Buying and quality

PROSEA warns that dried, powdered galangal is sometimes cut with powdered lesser galangal, which is one reason ground galangal isn’t traded in bulk.¹ We found no Codex or other grading standard for galangal.

Fresh rhizomes should be firm and smooth; skip any that are dried out, cracked or moldy.

Storage

We found no shelf-life figure for fresh or dried galangal from a regulator or standards body. For practical methods, see how to store galangal and can you freeze galangal?.

Health claims and safety

What the research does and doesn’t show

Galangal is used in traditional medicine; Britannica notes that its essential oils are used in Ayurveda.⁴ Claims that it treats disease are another matter.

• Cancer. Galangin and 1’-acetoxychavicol acetate have been studied for anticancer activity. A 2024 review of Alpinia research reports galangin results in cultured human cancer cells, a chemically induced liver-cancer model in rats and tumor models in mice, and ACA results in cultured cancer cells.⁵ The review describes no human trials. Lab and animal results like these don’t show that eating galangal treats or prevents cancer in people.
• Male fertility. In a randomized, double-blind, placebo-controlled trial, 66 men completed three months of daily tablets containing extracts of pomegranate fruit and galangal rhizome, or placebo. The average total motile sperm count rose 62% in the extract group and 20% in the placebo group.⁶ That’s one trial of a combined supplement, not of galangal alone or of galangal in your cooking.

You’ll also read that galangal is a significant source of dietary fiber or of the antioxidant kaempferol. We couldn’t trace either claim to a source.

Safety

Lead limits. In 2024 the Codex committee on contaminants agreed a lead maximum level of 2.0 mg/kg for spices in the “dried rhizomes and roots” group, which explicitly includes galangal, and the Codex Alimentarius Commission adopted lead limits for dried rhizomes and roots later that year.⁷⁸ The committee’s report notes that the proposed levels were based on data for ginger only.⁷

Substitutes and comparisons

Ginger is the usual stand-in, though it’s sweeter and less resinous. See galangal substitutes for the ranked list, and galangal vs. ginger and galangal vs. turmeric for side-by-side comparisons. Related rhizomes: zedoary and turmeric.
