  • Rhus chinensis has long been used in folk medicine in Asia.  Leaves, roots, stems, bark, fruit and particularly the galls on the leaves are recognized to have important preventative and therapeutic effects on different ailments. The leaf galls are produced in response to an aphid, Melaphis chinensis, and are rich in gallowtannis and other substances.  The plant is sometimes referred to as the Nutgall Tree.   The galls are a commercial product that is used in Chinese medicine for the treatment of coughs, diarrhea, night sweats, and dysentery.  Recent scientific research has shown that compounds from Rhus chinensis possess strong antiviral, antibacterial, anticancer, hepatoprotective, antidiarrheal and antioxidant activities [Phytotherapy Research 24:1739(2010].
