Rehmannia is used for diabetes, "tired blood" (anemia), fever, weakened bones (osteoporosis), and allergies; and as a general tonic.
Insufficient Evidence to Rate Effectiveness for...
- Anemia caused by bone marrow failure (aplastic anemia). Early research suggests that taking rehmannia along with the steroidal drug stanozolol might help improve symptoms of aplastic anemia better than stanozolol alone.
- Chronic lung disease (chronic obstructive pulmonary disease, COPD). Early research suggests that taking a Chinese herbal decoction containing rehmannia root and angelica (tongfei mixture) by mouth along with oxygen treatment might improve oxygen levels during the night better than oxygen treatment alone in people with COPD and low oxygen levels.
- "Weakened bones" (osteoporosis).
- As a general tonic.
- Other conditions.
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).

Special Precautions & Warnings:Pregnancy and breast-feeding: There is not enough reliable information about the safety of taking rehmannia if you are pregnant or breast-feeding. Stay on the safe side and avoid use.
