Chinese sumac

Chinese sumac, Chinese sumac nutgall tree or nurude（scientific name:Rhus javanica）is a small deciduous tree of the genus Rhus , native to Japan, Korea, China, Taiwan, and India. In Japan, it grows naturally on sunny hillsides in the plains and low mountains of Hokkaido to Okinawa. It is also known as fushinoki, kachinoki, gobaishi (go-baishi, chuei), kazunoki (kazunoki) in Manyo names, and Chinese sumac or Chinese sumac nutgall tree in English names. The height of the tree is 3 to 8 meters. The leaves are odd pinnate compound leaves about 30 cm long, spreading in alternate arrangements at the ends of branches. The leaves are green in color, but turn red in autumn. The lobes are oblong ovals 5-12 cm in diameter with coarse serrations on the leaf margins. The odd pinnate compound leaves have wings on the leaf axils between the lobes. The leaves are parasitized by the aphid family Nudibranchiaceae, which produces an insect mass. The plant is dioecious, with a conical inflorescence growing out of the phyllotaxy in August and September, bearing many small five-petaled flowers. The female flowers have one pistil and the male flowers have five stamens. The wood is used for craftwork, and the insect bumps on the leaves are used to make the crude drug "gobai shi. Gobaishi has antidiarrheal, hemostatic, antiphlogistic, antiphlogistic, antitussive, and relieving effects on swellings in the mouth and toothache. In the Edo period (1603-1867), the insect bumps and berries were powdered and mixed with iron nails to make a black dye used to make tooth blackening for married women. Since nurude is a member of the poison ivy family, people with sensitive skin should be careful, as it may cause irritation.
