Sichuan pepper
The dried husk of a citrus-family berry that produces a tingling numbness rather than heat — the sensation called ma in Chinese. It is not a pepper, not related to pepper, and the numbness is a mechanical vibration of the nerves rather than a taste.
Identity
- Botanical name
- Zanthoxylum bungeanum
- Family
- Rutaceae
- Part used
- Fruit
- Origin
- Most of China and into Bhutan; Sichuan is the trade centre and the source of the prized Hanyuan crop rather than the whole range

- Sichuan, Shaanxi, Nepal, Japan
Character
Citrus-peel aroma followed by a distinct buzzing numbness on the lips and tongue. The numbness is the point and it is unlike anything else in the spice cabinet.
Notes: grapefruit peel, pine, pepper
History
Used in Chinese cooking long before chillies arrived from the Americas, and the numbing half of Sichuan’s málà is the older half by centuries. The United States banned imports from 1968 to 2005 over a citrus canker concern, which is why Sichuan cooking outside China was mis-seasoned for a generation.
How it is drunk
Central to Sichuan and Chongqing cooking, used in Nepali timur, Bhutanese and Tibetan food, and as Japanese sanshō on grilled eel. It appears in spiced drinks in western China rather than as a solo infusion.
Production
Berries are picked at ripeness and dried until the husk splits from the black seed, and the seed is discarded — it is gritty and carries no aroma. Good material is bright red-brown, and the black seeds left in cheap stock are a straightforward grading signal.

Boiling and decoction
1–3 g/100 ml · 98–100 °C · 5 min
What gets confused
Red and green Sichuan pepper are different species with different characters, and Nepali timur and Japanese sanshō are further relatives. The presence of black seeds means the material has not been properly sorted.
Common mistakes
- Grinding the seeds in with the husks. They are gritty and dilute the numbing effect.
Related botanicals
- Black pepper — Not a pepper and not related to one. It produces a tingling numbness rather than heat, which is a mechanical sensation rather than a taste.
Comparisons
- Sichuan pepper vs black pepper — One produces heat and the other produces numbness, and they are unrelated plants. The tingling of Sichuan pepper is a mechanical sensation rather than a taste, which is why no amount of black pepper reproduces it.
Evidence for this page
The botanical name, family and distribution above are checked against an external authority. Zanthoxylum bungeanum Maxim. — GRIN-Global Taxonomy record— retrieved and read, not countersigned by a named human. That source covers naming and distribution only. Everything else on this page — history, culture, production, flavour, preparation and buying advice — is TeaHQ’s own synthesis with no external source behind it.
Brewing parameters here are typical practice for the category rather than measurements of this plant, and each set says so.
This page makes no safety claim. It describes what Sichuan pepper is, where it comes from and how it is prepared — not what it does to a person. The absence of a safety note here is not a statement that the plant is safe. How TeaHQ handles this.
