Rehmannia glutinosa is a flowering broomrape, and one of the 50 fundamental herbs used in traditional Chinese medicine, where it has the name shēng dì huáng (Chinese: 生地黄).

It is often sold as gān dì huáng (Chinese: 干地黄), gān meaning "dried".

Unlike the majority of broomrapes, R. glutinosa is not parasitic, and is capable of independent photosynthesis.

A number of chemical constituents including iridoids, phenethyl alcohol, glycosides, cyclopentanoid monoterpenes, and norcarotenoids, have been reported from the fresh or processed roots of R.
