Gan Di Huang Tincture & Alcohol-Free Extract

Gan Di Huang (Rehmannia glutinosa), the Chinese foxglove, is a low, sticky-haired perennial of the broomrape family, Orobanchaceae, native to northern China. It forms a rosette of wrinkled, oval leaves and a stalk to 30 cm bearing tubular, purplish-brown flowers with a yellow throat that resemble foxgloves. The fleshy, orange-yellow root turns black and soft after drying, when it is called gan di huang, and darker and sweeter after steaming with wine as shu di huang. We extract the dried root and the dried prepared root separately.
