Description:
Rehmannia is a very commonly used herb in traditional Chinese medicine. Know as or Di-huang, (earth yellow), prepared rehmannia is used for loss of blood, yin deficiency, lower back pain with kidney deficiency from overwork (it replenishes the vital essence of the kidneys),lumbago, cough, hectic fever, diabetes, urinary incontinence, deafness, uterine bleeding, vertigo, tinnitus, and for regulating menstrual flow. Rehmannia has astringent properties that make it useful in stopping bleeding. It helps to protect and support the liver and
adrenal glands.

Function:
1. Rehmannia has been used extensively in traditional Chinese medicine (TCM). Although thorough clinical trials are lacking, rehmannia has been used to treat rheumatoid arthritis, asthma, urticaria, and chronic nephritis in Chinese studies. Rehmannia may also be used to prevent the suppressive effects of corticosteroid drugs on endogenous levels.
2. Rehmannia looks promising in treating aplastic anemia,mitigating side-effects of chemotherapeutic agents and HIV medications, curing obdurate eczema, relieving pain from lung or bone cancer or disc protrusion, and helping ameliorate lupus nephritis and type 2 diabetes with hyperlipidemia. However, presently, there are no high-quality, large randomized, controlled trials supporting the efficacy of rehmannia for any of these indications.
3. Rehmannia is generally regarded as safe when used short-term (less than 3-4 months). Few case-reports document adverse effects of rehmannia noting hypoglycemia, hemorrhage, and fever. Often rehmannia is used in combination with other herbs, making it difficult to assess which effects are truly due to rehmannia or other ingredients.
