An extract made from a tree commonly found in China. It is also known simply by its genus name Zanthoxylum or by colloquial names such as winged prickly ash.
The fruit of Zanthoxylum is used to make Sichuan pepper spice. It has pain-relieving, anti-oxidant, anti-fungal, and anti-inflammatory properties. Lubricants sometimes use Zanthoxylum extract to create a pleasurable warming or tingling sensation.
While it is a fairly well-tolerated substance, Zanthoxylum may cause irritation or unpleasant burning sensations in some users. Despite this, it is generally considered to be safe and non-carcinogenic.
