Chinese gall, also referred to as Chinese gallnuts (or nutgalls), is a plant excretion produced when irritants are released by the larvae of gall insects, such as those of the Cynipidae family, the gall wphps. A major commercial source of medicinal gallnuts is oak trees, which yield the Chinese herb moshizi, but a similar material is found on Chinese sumac (Rhus species), produced by the activities of a type of aphid; these galls are called wubeizi by Chinese herbalists. The plant secretes the liquid gall, comprised mainly of tannins, that hardens to become the "nut." Gallnuts are a native product of China and Southeast Asia, but are also produced in small amounts in Turkey, India, Japan, and Korea. The annual yield of gallnuts in China is about 95% of the total world yield. Guizhou and Yunnan are the biggest gallnut-producing areas in China.hydrolyzable tannins are readily degraded into smaller molecules. Hydrolyzable tannins are present in many different plant species but are found in particularly high concentrations in nutgalls growing on Chinese.
