Rehmannia Root is a native of China and is one of the first species of the genus to be introduced and cultivated in the West.  It thrives in light, moist, well-drained, neutral-to-acid, sandy soil in full sun; and when cultivated, the thick, reddish-yellow roots are lifted in autumn or early winter for use in herbal medicine.  It has been called Chinese Foxglove due to its superficial resemblance to the genus, Digitalis, or Common Foxglove.  At the moment, the current placement of the genus is uncertain; it is said to belong neither to the family Scrophulariaceae nor Plantaginaceae , to which many other former Scrophulariaceae have been transferred.  Rehmannia Root is one of the most popular tonic herbs in Traditional Chinese Medicine (TCM), where it has been used for thousands of years.  Listed as one of the fifty most important Chinese herbs, it was first mentioned in Chinese medical literature during the Han Dynasty (206 B.C.- A.D.23).  The fresh or dried roots have been used in China for centuries to treat a long list of ailments and was even used as a tonic to counter the effects of ageing!  The roots were steamed in rice wine, known as shu di huang, and were described in the Illustrated Classic of the Materia Medica by Su Song (A.D. 1061).  Some of the constituents included in Rehmannia Root are beta-sitosterol, calcium, copper, glucose, glucosamine, histidine, mannitol, zinc, amino acids and vitamins A, B, C and D.
