Other names
What this spice is called elsewhere, and where the translation is not clean.
makwaen
Thai — Northern Thailand
Romanised in several ways (makwaen, ma kwaen, makhwaen). Other Zanthoxylum species are sold in the region too; the catalogue records the coastal Indian Z. rhetsa separately as tirphal.
maqian
Mandarin — South-western China
In Chinese sources the name belongs to the variety pubescens of the same species.
Flavour and aroma
Hot and pungent, and used to add spiciness as well as aroma to a meal.
Strong and distinctive: the fruits, leaves and branches are all intensely aromatic, and the fruit oil is dominated by limonene, with α-pinene, β-myrcene and linalool behind it.
Heat
Pungency scale: none — this spice is not pungent
Described as hot and pungent. Which compound carries the pungency is not established in the sources held, and no numbing is described.
- Limonene — About two-thirds of the fruit oil in the analysis cited (67.06%), and the main constituent of the seed coat, seed and whole-fruit oils as well: the citrus note.(what limonene is)
- α-Pinene, β-myrcene and linalool — The next most abundant, at 6.49%, 3.87% and 2.96% of the fruit oil: resinous, herbal and floral notes behind the limonene.(what α-pinene is, what linalool is)
Pairings
Ranked by how well established the combination is, with the reason and the caveats attached.
Foods
White fish
GoodWhere it grows, local people use the fruit as a spice for boiling fish. The source names no particular fish, and white fish stands in here for fish in general.
Preparation and use
Crush the fruit just before use. The aroma is volatile, so it is best added late or to dishes cooked briefly.
A pungent, citrus-scented spice for meat and fish in northern Thailand and south-western China, used fresh or dried. The sources describe its use by region rather than by dish.
Storage and freshness
| Form | Good for | Conditions | Fridge |
|---|---|---|---|
| Dried whole | Not established | Cool, dark, dry and sealed. | No |
| Fresh | Not established | Refrigerated, and used within days. | Yes |
Crush a fruit: it should smell strongly and at once.
- A faint, dusty smell on crushing
- Loss and oxidation of the volatile oil, which flattens the citrus aroma
Quality is not the same as safety
Faded dried fruit is a quality matter. Fresh fruit is a fresh food and is discarded if mouldy.
Forms
These forms differ enough to need separate answers: treating them as interchangeable produces a dish that is wrong.
Fresh fruit
Used fresh where it grows.
Dried fruit
Dried whole, crushed or ground before use.

Botany
The species has two varieties; the Chinese maqian is var. pubescens.
Rutaceae
The citrus family, with Sichuan pepper and the other Zanthoxylum spices.
The fruit, fresh or dried. The branches and leaves are aromatic too, from small oil glands.
A tree of southern and south-western China and of tropical Vietnam, Myanmar, India and other South-East Asian countries, whose branches, leaflets and fruits all carry a strong aroma from small oil glands.
Commonly confused with
Another Zanthoxylum, and the one most cooks know. Sichuan pepper is defined by the numbing of its sanshools; no source found for makwaen describes numbing, and its recorded aroma is dominated by limonene.
Zanthoxylum rhetsa, used on India’s western coast. A different species, recorded separately.
The Zanthoxylum of Batak cooking in North Sumatra. A different species from a different region.
How it is grown
The plant, how it is propagated and farmed, what threatens the crop, and where it is produced now. Crop diseases here are plant health, not food safety.
The small aromatic fruit, used fresh or dried, of a tree whose branches and leaves are aromatic too.
Where it comes from and how it is made
Southern and south-western China and tropical South-East Asia, including Vietnam, Myanmar and India.
- Thailand (The north) — notable producer. Where makwaen is chiefly found and used as a spice.
- China (The south and south-west) — notable producer. Where the variety pubescens is used as the flavouring maqian.
- Vietnam — native range
- Myanmar — native range
- Picking — The fruits are gathered from the tree.
- Drying — Used fresh, or dried whole; in the study that dried them for oil extraction, drying took them to a constant weight.
Buying and quality
Whole, crushed at the moment of use. The aroma is a volatile oil, and a ground powder loses it quickly.
- A strong aroma when a fruit is crushed.
- Sold under the Thai or Chinese name; "prickly ash" alone may mean another Zanthoxylum.
Culture
Recorded by tradition rather than merged into one narrative — these are genuinely different practices.
Northern Thailand
Local communities prefer its fresh and dried fruits as a traditional spice, to add spiciness and lift the flavour of their meals.
- As a spice, fresh or dried
Also documented in northern Thailand: Cha phlu, Litsea berry, Thua nao, Vietnamese coriander.
South-western China
As maqian, the variety pubescens is used widely as a food flavouring, and local people use the fruit as a spice for roasting meat and boiling fish.
- With roast meat
- With boiled fish
The fruit and other parts have medicinal uses where it grows. Recorded as context only; SpiceHQ makes no health claim.
