Chinese gallnut is the gall produced mainly by parasitic aphids of Melaphis chinensis (Bell) Baker on the leaf of Rhus chinensis Mill., Rhus potaninii Maxim, or Rhus phunjabensis Stew. var. sinica (Diels) Rehd. et Wils.

It is a plant excretion produced when irritants are released by the larvae of gall insects, such as those of the Cynipidae family, the gall wasps.
