The plant produces small, aromatic flowers that are dioecious (having male and female flowers on separate plants). The fruit of Zanthoxylum armatum is a capsule that splits open to reveal black seeds surrounded by a fragrant, spicy pericarp.

Culinary Uses

The dried fruits (often referred to as berries) and seeds of Zanthoxylum armatum are used as a spice in various cuisines. They are known for their unique flavor, which is slightly numbing and has a citrus-like aroma. In Nepalese cuisine, the spice is used in pickles, chutneys, and meat dishes. It is also an essential ingredient in the traditional Sichuan cuisine of China, where it is used alongside Sichuan pepper to create the characteristic "ma la" (numbing and spicy) flavor.

The bark and fruits are used to treat toothache, hence the common name "Toothache Tree". It is also used for digestive problems, fever, and as a general tonic.
