REHMANNIA: Overview, Uses, Side Effects, Precautions, Interactions, Dosing and Reviews

Overview

Rehmannia (Rehmannia glutinosa) is a plant mainly grown in China. It's commonly used in combination with other herbs in Traditional Chinese Medicine (TCM).

Some chemicals in rehmannia might affect the immune system and nervous system. Rehmannia might also reduce pain and swelling.

People use rehmannia for kidney disease, anemia, obesity, diabetes, and many other conditions, but there is no good scientific evidence to support these uses.

Long-term kidney disease (chronic kidney disease or CKD). Taking rehmannia by mouth along with the drug irbesartan might decrease the amount of protein in the urine in people with this condition.

There is interest in using rehmannia for a number of other purposes, but there isn't enough reliable information to say whether it might be helpful.
