Rhus chinensis, the Chinese sumac[1] or nutgall tree, is a plant species in the genus Rhus.

The species is used to produce galls, called Chinese gall, Galla Chinensis or Wu Bei Zi (五倍子) in Chinese, which are rich in gallotannins,[2][3] a type of hydrolysable tannins. The infestation by Chinese sumac aphids (Melaphis chinensis Bell) can lead to a gall which is valued as a commercial product. Chinese galls are used in Chinese medicine to treat coughs, diarrhea, night sweats, dysentery and to stop intestinal and uterine bleeding.[4]

Rhus chinensis compounds possess strong antiviral, antibacterial, anticancer, hepatoprotective, antidiarrheal and antioxidant activities.[5] The gall of Rhus chinensis, Galla chinensi, has long been considered to possess many medicinal properties.[6]

Gallic acid (3,4,5-trihydroxybenzoic acid),isolated from Rhus chinensis, induces apoptosis in human monocytic lymphoma cell line U937 and may be a potential chemotherapeutic agent against lymphoma.[7] The gall of Rhus chinensis inhibits alpha-glucosidase activity.[8]
