From a plant native to Szechuan Province in China. It grows on trees, and so differs from black pepper, which grows on climbing vines. Used extensively in Szechuan cooking, Szechuan pepper is known for the “numbing” sensation it produces on the tongue. For more information, see the entry for _Zanthoxylum Bungeanum_ Fruit Oil.
