Rhus coriaria Fruit Identity & Plant Part
The botanical entity is Rhus coriaria L., sumac, a shrub of the Anacardiaceae from the Mediterranean and western Asia. The part used is the fruit, the clustered, hairy red drupes that ripen in late summer. Leaves, bark and wood are not part of this ingredient, although those parts are used elsewhere as tanning material.
Sumac extract should not be confused with poison sumac, which is a Toxicodendron species, or with the North American staghorn sumac, Rhus typhina. The fruit carries hydrolysable tannins, gallic acid, flavonols, anthocyanins in the skin and malic acid, which is the main source of its sourness. These are named as families only.
