Zanthoxylum gilletii

Zanthoxylum gilletii, the East African satinwood, is a tree species in the genus Zanthoxylum found in Africa. The fruits are used to produce the spice uzazi, which is the Nigerian (Igbo language) name of both the plant and the spice. It is native to Central and West Africa, and a close relative of the Sichuan pepper. "Uzazi" usually refers specifically to the spice made from its fruit and pericarp, though sometimes other parts of it such as its leaves are used.
