This product is the gall formed by the larvae of the Nutgall wasp (Cynips gallae-tinctoriae Olivier) on the young branches of the Nutgall tree (Quercus infectoria Olivier) of the Fagaceae family. It is produced in regions such as Greece, Turkey, and Iran. The Nutgall wasp is black, about 6 millimeters in length, and its larvae resemble maggots, being extremely tiny. Typically, the galls are collected between August and September before they are perforated, and then dried. Galls that are large, heavy, and gray in color are considered superior, while those that have been perforated are of lesser quality.
