Application

Yanmin has been exploited for multiple medicinal functions with its fruits, roots and leaves. The fruits are the primary ingredient of a traditional Chinese medicine Ren mian zi; it can effectively invigorate spleen and promote detoxification. The root barks are collected for the root of Indochina Gragonplum for treating skin diseases. The leaves are processed into leaf of Indochina Gragonplum for treating furunculosis. 

Apart from medicinal versatility, the fruits are esculent and often processed into pickled fruits and Chinese gooseberry sauce for seasoning. The heartwood is dense, shiny and durable, with notable rot-resistant ability; therefore, it is highly yearned for making furniture and constructions. The extracted seed oil can be processed into soap and lubricant. 

By virtue of its lofty height, ornamental trees and handsome tree crown in rounded shape, the tree is often planted as a shade in parks and gardens.
