Rhus chinensis, the Chinese sumac,[1] or nutgall tree, is a plant species in the genus Rhus.
Galls produced on the species that are called Chinese gall, Galla Chinensis, or Wu Bei Zi (五倍子) in Chinese, are a source of gallotannins,[2][3] 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.[4] Some research has suggested that chemical compounds found in Rhus chinensis possess in vitro antiviral, antibacterial, anticancer, hepatoprotective, antidiarrheal, and antioxidant activities.[5] However, it is important to note that this evidence is not substantiated by multiple international researchers. The aqueous extracts of the gall also inhibit alpha-glucosidase activity in vitro.[6]
