Glycyrrhiza Uralensis Licorice Root (Gan Cao, Radix Glycyrrhizae) Licorice root, also known as Gan Cao and Radix Glycyrrhizae, is one of well-known herbs primarily used as a harmonizer in Chinese herbal formulas.

In fact, this herb has long been used as medicine in ancient China since 2,000 years ago, which was recorded in the oldest herbology classic of “Shen Nong’s Herbal Classic” and listed as one of the superior drugs there. In addition, it was highly regarded as “the Teacher of Emperors” in the kingdom of herbs by Tao Hongjing, a famous physician in the Southern Dynasties (420-589).
