Rhus chinensis, the Chinese sumac[2] or nutgall tree, is a deciduous shrub or small tree in the genus Rhus. Growing to 6 m (20 ft) tall, it has downy shoots and leaves comprising several leaflets. These turn red in autumn before falling.[3]

The plant is common in East and South Asia,[4] and is cultivated as an ornamental in temperate climates.

Galls produced on the species that are called Chinese gall (Galla chinensis), are a source of gallotannins,[5][6] molecules of hydrolyzable tannins. Infestation of the tree by Chinese sumac aphids (Melaphis chinensis Bell) may lead to production of a gall that is valued as a commercial product in China.

Chinese galls are used in traditional Chinese medicine for coughs, diarrhea, night sweats, dysentery, and intestinal and uterine bleeding.[7] Some research has suggested that chemical compounds found in Rhus chinensis possess in vitro antiviral, antibacterial, anticancer, hepatoprotective, antidiarrheal, and antioxidant activities.[4] The aqueous extracts of the gall also inhibit alpha-glucosidase activity in vitro.[8]
