Yam mucin can improve the immune function and cardiovascular function of animals. Dehydroepiandrosterone contained in yam also has many anti-aging effects, such as enhancing immune function, improving memory, calming and sleeping, delaying skeletal muscle aging, preventing arteriosclerosis and so on.
