Kidney’s Own Food

Rehmannia Glutinosa is very popular in Chinese medicine, where it is considered to be a longevity tonic. The species name “glutinosa” comes from “glutinous”, referring to the sticky nature of the root.

Our Rehmannia Root is processed traditionally, by boiling the root in a mixture of yellow wine and black bean infusion until the liquids have been boiled away and the roots are black. The roots are then dried in the sun.

Health Benefits of Rehmannia
Rehmannia is said to be the “Kidney’s Own Food.” It is thus believed to be a Kidney tonic and longevity herb and is found in many common “anti aging” formulations for longevity, and rejuvenation.

Rehmannia is one of the most important Chinese herbs for supporting the kidneys and adrenal glands, and is even thought to support the pituitary gland. Rehmannia also appears to combat adrenal suppression caused by steroid hormones and has a similar tonic effect on the adrenal cortex as licorice.

Thought to be powerfully immuno-supportive, Rehmannia is also used to help promote a healthy inflammation response, along with herbs such as bupleurum. It is also known to support libido, joint health, respiratory health, and healthful aging.
