The walnut tree has very high-quality wood, which is used in carpentry and making musical instruments, while the bark is used for wickerwork, but from the shell of the nut, tannins and brown color are obtained. Different parts of the plant are also used in medicine, for example, furunculosis is treated with fresh leaves by applying them to wounds; a very delicious medicinal jam is made from the green nuts when they are not yet fully ripe, usually in June.
