(Chinese sumac), Rhus potaninii Maxim. (potanin sumac) or Rhus punjabensis var. sinica (Diels) Rehd. et Wils. (red-punjab sumac), a deciduous dungarunga of the family Anacardiaceae, which is mainly formed by the parasitism of an insect called the "gall aphid".

The decidious tree grows to about 6 m tall. It is in flower in August. The flowers are dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required) and are pollinated by bees. The plant cannot grow in the shade. It requires moist soil.

In China, it is distributed in most areas but mainly produced in Sichuan province. Picked off in autumn, the parasites in the gall are boiled to death and dried for use when raw.

Chinese Gall is a kind of special local product of China, and an important traditional commodity for export. China is the biggest origin of Galla chinesis and share about 90% more output of the world, with good fame of both out put,kinds and quality, so the Galls named Chinese Gall or East Gall.
