Rehmannia – Nature’s All-Around Tonic

Rehmannia glutinosa, particularly its root, is traditionally used in Japanese and Chinese medicine. It is feels cold to the tongue, and can be sweet or bitter. It is primarily found in Northeastern China and has been used for over 2,000 years. It is said to contain Vitamins A, B, C, amino acids, cerebroside, dammelittoside, melittoside, and rehmaglitin.

Rehmannia has a number of other common names such as Di-Huang or Earth yellow, Chinese foxglove, and Di-sui or Earth marrow. Its main therapeutic actions benefit the heart, kidney, and liver.


  • Improves fluid production
  • Lowers body temperature
  • Alleviates aplastic anemia
  • Decreases blood sugar levels
  • Exhibits anti-inflammatory effects
  • Serves as a potent anti-osteoporotic
  • Provides tonic effects
  • Improves Symptoms of Aplastic Anemia

Rehmannia’s ability to boost blood production is a popular area of research. The processed root is said to work directly on the bone marrow, which explains why it provides potent and quick results.

Decreases Blood Sugar Levels The herb has been found to decrease blood sugar levels, although excessively at times. Close monitoring is crucial when taking rehmannia as an anti-diabetic, especially when it’s used alongside prescribed medications.

Anti-Inflammatory Catalpol, an iridoid glucoside present in rehmannia, stimulates the adrenal cortex to produce more hormones. These hormones are responsible for the anti-inflammatory effects associated with the medicinal root, prompting its use in treating conditions such as urticarial (otherwise known as hives) and eczema.

Anti-osteoporosis The restorative property of rehmannia explains why the Chinese have been using it for centuries. It is said to increase the resorption of calcium, not only preventing osteoporosis but also facilitating the repair of broken bones and growth centers.

General Tonic Rehmannia is one of the most frequently used tonic herbs. It is taken to improve liver health, as well as to enhance kidney function and urinary tract condition. It also features anti-aging properties, providing improved stamina as seen among subjects in several studies.

Rehmannia is a common traditional ingredient available in pill, liquid, tea, and powder forms. Since it is a common ingredient, studies have yet to show its full effects in isolation, leading some to question its effectiveness. In addition, there are those quite worried about its potential side effects, although only dizziness, nausea, vertigo, and fatigue have been recorded.

Still, with all things considered, especially given the fact that it improves health at a holistic level, rehmannia is truly one of nature’s greatest gifts to humanity.
