What is galangal?
Galangal is the rhizome of plants of the genus Alpinia in the ginger family (Zingiberaceae); the two commercial species are Alpinia galanga (greater or Thai galangal) and Alpinia officinarum (lesser or Chinese galangal). The rhizome is used fresh, dried in slices or ground, and looks like ginger but is harder, redder and less fibrous. It is kholinjan in Egypt and the Levant, kholinjan or khalanjan in Iraq and the Gulf, khoudenjal in the Maghreb and kulinjan in India. It reached the Arabs along the spice route from China and India; Ibn Sina and Dawud al-Antaki listed it as a warming digestive, and it became a pillar of the attar's shop, an ingredient in energy mixes, in the Arabic coffee of some Gulf regions, in Moroccan ras el hanout and some Iraqi meat seasonings, while Thai and Indonesian cooking keep it as a core spice for soups and curries.
Types, varieties and origins
The species differ: greater galangal is more aromatic and citrusy with less heat; lesser galangal is hotter, more bitter and peppery, and is usually what the Arab herbal trade means.
Fresh galangal
Large rhizomes of Alpinia galanga from Thailand, Indonesia, Malaysia and Vietnam, pale cream with pink rings and red shoots and a penetrating pine-citrus-ginger aroma, sliced into Asian soups and curries and requested by Asian restaurants in Egypt and the Gulf.
Dried galangal slices
Thick reddish-brown slices, usually Chinese Alpinia officinarum from Hainan and Guangdong, the Arab herbal trade's traditional form for centuries; hard, boiled, steeped or ground, with a strong hot peppery flavour and a faint camphor note.
Ground galangal
A light-brown powder milled from selected slices for spice mixes, Arabic coffee and herbal blends; it loses aroma faster than slices.
| Variety | Origin | Character | Best use |
|---|---|---|---|
| Fresh (Alpinia galanga) | Thailand, Indonesia, Vietnam | Cream and pink, pine-citrus aroma, moderate heat | Asian soups and curries, marinades |
| Dried slices (usually A. officinarum) | China (Hainan, Guangdong) | Hard reddish brown, hot peppery with camphor note | Herbal trade, decoctions, traditional blends |
| Ground | Milled in Mansoura | Light hot aromatic powder | Spice blends, Arabic coffee, drinks |
Quality standards and grades
There is no dedicated ISO standard for galangal, so the general spice standards apply (ISO 948 sampling, ISO 939 moisture, ISO 6571 volatile oil, ISO 928 ash) with ASTA cleanliness specifications and ESA limits. The pharmacopoeial reference is the Chinese Pharmacopoeia, which sets minimum volatile oil and extract for Alpinia officinarum rhizome; in Egypt the general Egyptian Standards for spices and dried herbs apply, and imports are tested for pesticides, heavy metals and aflatoxin like other dried roots.
| Parameter | Typical acceptable range | Note |
|---|---|---|
| Moisture (dried) | ≤ 12 % | Typical for dried roots |
| Volatile oil | 0.5–1.5 % (greater), 1–2.5 % (lesser) | Typical, not mandatory |
| 1,8-cineole in oil | 20–50 % | Main component in greater galangal |
| Total ash | ≤ 7 % | Typical |
| Acid-insoluble ash | ≤ 2 % | Sand and soil |
| Extraneous matter | ≤ 2 % | Other roots and stems |
| Mouldy or insect-damaged slices | ≤ 1 % | Storage indicator |
| Total aflatoxin | ≤ 10 µg/kg | Common spice limit |
By the senses: good slices are hard, heavy, uniformly reddish brown, sharp-smelling when snapped, with a peppery pungency that builds on the tongue; light, pale or spongy slices are old or already extracted, and white spots or mustiness show damp storage. Fresh rhizome should be firm and glossy, without wrinkles or softness.
Fresh, dried and ground
Fresh galangal is lightly peeled and thinly sliced or bruised, cooked in liquids and removed like a bay leaf. Drying concentrates the heat and softens the citrus aroma, so dried does not easily replace fresh in Asian dishes; slices are soaked 20 minutes in warm water or boiled directly. Ground galangal goes in at the end of cooking or into drinks, and is best milled in small quantities because the volatile oil evaporates within months.
Culinary uses
- Egypt: in herbal-shop energy and warming mixes with ginger and cinnamon, in some winter drink recipes, and in Asian restaurants.
- Iraq: in some meat spice mixes and Mosul kubba, in winter decoctions, and in some rice dishes of Indian origin.
- Levant: in the Aleppo seven- and nine-spice blends, in some kubba and sujuk recipes, and in the herbal trade with ginger and cloves.
- Gulf: in some Najdi and Kuwaiti Arabic coffee blends with cardamom and ginger, in madhbi and machboos spices, and in fish mixes.
- Asia: Thai tom kha and tom yum soups, Indonesian rendang and Malaysian curries.
Dosage: two or three dried slices per litre of stock or drink, a quarter teaspoon of ground per kilogram of meat in blends, and 3–5 fresh slices per litre of soup. It pairs with ginger, lemon, lime, cardamom, cinnamon, coconut milk, chilli and coriander.
Storage and shelf life
Fresh galangal keeps 2–3 weeks wrapped in paper in the refrigerator, or sliced in the freezer for 6 months; dried slices keep 2–3 years airtight away from humidity, and ground galangal 6–12 months. Damp storage brings mould and insects.
Traditional and health benefits
Classical Arab medicine treats galangal as a warming digestive and stomach tonic, used for nausea and bad breath, steeped for joint pain and colds, and added to energy and vitality mixes. Research studies its compounds (galangin, kaempferide and gingerols) for antioxidant, anti-inflammatory, antimicrobial and anti-nausea properties. Excess can cause heartburn.

FAQ
What is the difference between galangal and ginger?
Same family, but galangal is harder and redder with a peppery pine-citrus flavour, while ginger is hot, sweet and fibrous; neither fully replaces the other.
Can I use dried galangal instead of fresh in Thai soup?
In a pinch, after soaking, but dried is hotter and less citrusy; use a third of the amount and add lime zest to make up the aroma.
Which type is the herbalist's galangal?
Chinese dried slices of lesser galangal are the traditional form in the Arab herbal trade, and the hottest and strongest.
How do I prepare a galangal drink?
Boil two or three slices in two cups of water for 10 minutes with a little ginger and cinnamon, sweeten with honey, and drink warm in winter.
