Ku Shen is the Chinese term for the root of Sophora flavescens, a member of the Bean and Pea family, Leguminosae. Found growing wild throughout China in sunny meadows and roadsides, it is also cultivated, mostly in the Shanxi and Hubei provinces.

S. flavescens naturally contains about 2% of these compounds in its root stock.

Other species of Sophora also contain these valuable constituents. S. japonica and S. angustifolia are also called Ku Shen in the Chinese Pharmacopeia, because in Traditional Chinese Medicine, they were found to have properties and applications nearly equivalent to those of S. flavescens. S. subprostrata is also quite similar but is distinguished as Shan Dou Gen. Both types of TCM herb are bitter, cold
