Sichuan pepper (, also known as Sichuanese pepper, Szechuan pepper, Chinese prickly ash, Chinese pepper, Mountain pepper, and ''mala'' pepper, is a spice commonly used in Sichuan cuisine in China, Bhutan and in northeast India. It is called mejenga in Assam, India. It is called thingey (ཐིང༌ངེ༌) in Bhutan and is used in preparing ezay (a side dish similar to chutney), to add spiciness to rice porridge (ཐུགཔ་), ba-thup and noodle (buckwheat noodles similar to soba) and other snacks. It is extensively used in preparing blood sausage throughout Bhutan, Tibet and China. Despite its name, Sichuan pepper is not closely related to black pepper or chili peppers.

Culinary uses

Sichuan pepper is an important spice in Chinese, Nepali, Kashmiri, north east Indian, Tibetan, and Bhutanese cookery of the Himalayas. Sichuan pepper has a citrus-like flavor and induces a tingling numbness in the mouth, akin to a 50-hertz vibration, due to the presence of hydroxy-alpha sanshool. Food historian Harold McGee describes the effect of sanshools thus:


Chinese cuisine

Whole, green, freshly picked Sichuan pepper may be used in cooking, but dried Sichuan pepper is more commonly used. Once dried, the shiny black seeds inside the husk are discarded, along with any stems; the husk is what we know as Sichuan pepper or peppercorn. The peppercorn may be used whole or finely ground, as it is in five-spice powder. '' Ma la'' sauce (; ), common in Sichuan cooking, is a combination of Sichuan pepper and chili pepper, and it is a key ingredient in Chongqing hot pot. Sichuan pepper is also available as an oil (, marketed as either "Sichuan pepper oil", "Bunge prickly ash oil", or "huajiao oil"). Sichuan pepper infused oil can be used in dressing, dipping sauces, or any dish in which the flavor of the peppercorn is desired without the texture of the peppercorns themselves. () is a mixture of salt and Sichuan pepper, toasted and browned in a wok, and served as a condiment to accompany chicken, duck, and pork dishes. The leaves of the sichuan pepper tree are also used in soups and fried foods.


Other regions

One Himalayan specialty is the ''momo'', a dumpling stuffed with vegetables, cottage cheese, or minced yak or beef, and flavored with Sichuan pepper, garlic, ginger, and onion. In Nepal, the ''mala'' flavor is known as ' (). In Korean cuisine, is often used to accompany fish soups such as '' chueo-tang''. In Indonesian Batak cuisine, '' andaliman'' is ground and mixed with chilies and seasonings into a green ''sambal'' or chili paste. ''Arsik'' is a typical Indonesian dish containing ''andaliman''.


Medicinal uses

In Traditional Chinese medicine, '' Zanthoxylum bungeanum'' has been used as a herbal remedy. It is listed in the Pharmacopoeia of the People's Republic of China and is prescribed for ailments as various as abdominal pains, toothache, and eczema. However, Sichuan pepper has no indications or accepted case for use in evidence-based medicine. Research has revealed that ''Z. bungeanum'' can have analgesic, anti-inflammatory, antibacterial, and antioxidant effects in model animals and cell cultures. In rabbits, '' Z. armatum'' was experimentally investigated for its potential use in treating gastrointestinal, respiratory, and cardiovascular disorders.
