Rehmannia glutinosa is a perennial plant that can grow up to 6-12 inches tall. It prefers moist, sandy, or loamy soil. The yellow-brown or violet bell-shaped flowers, which have both male and female organs, look a lot like Foxglove and are pollinated by insects. Rehmannia roots and rhizomes contain over 70 active compounds that include a variety of amino acids, vitamins A, B, C, and D, and polysaccharides. Rehmannia is used in Asia in decotions for supporting the body while making blood and to relieve fatigue.
History and Folklore:
Rehmannia has more than a thousand-year history of cultivation in China. It is relied on as one of the most popular herbal tonics in traditional Chinese medicine (TCM). The genus name “Rehmannia” honors botanist Joseph Rehmann, while “glutinosa” means glutinous, sticky, or glue-like, referring to the sticky leaves, stems, and roots. In TCM, Rehmannia is one of the primary ingredients in tonics designed to help the body make blood.
