Ths sumac plant.
Sumac is s versatile plant and native in the Mediterranean region and Central Asia. It can reach the size of a small tree at a height of one to three meters and is characterized by soft, deep green leaves, which usually lead to prolonged allergic skin irritations due to the irritant containing urushiol. Only 15 to 30% of all humans are immune against the substance, while 25% of the world's population is particularly sensitive to urushiol. The flowers are yellow-green and the fruits orange-red.
The leave-tannins of the sumac are used for the leather production. Its tannin content is 13 to 28%. The bark can be used as a colouring agent for textiles and wool, while the dried, ripe fruits of the plant (the immature fruits are poisonous) are processed as a sour spice for Arabian and Iranian dishes.
