Jinliao Ku Jing Wan is composed of salvia seeds, fructus fructus, lotus seed, dragon bone, oyster and lotus seed, which has the efficacy of fixing the kidney and astringent essence, and is commonly used clinically for treating symptoms such as seminal emission, lassitude (mental fatigue, physical weakness), limb weakness, lumbago, tinnitus, and so on, which are caused by the lack of solidity of the kidneys.
