Licorice (Glycyrrhiza uralensis Fisch.), also known as Guolao, Sweet Grass, and Red Licorice, is a perennial herbaceous plant in the Fabaceae family. It typically includes Swollen Licorice and Smooth Licorice. The roots and rhizomes are harvested in spring and autumn, with fibrous roots removed and the remaining parts dried for medicinal use. Wild licorice is distributed across regions from Northeast China (Heilongjiang, Liaoning, Jilin), North China (Hebei, Shanxi, Inner Mongolia), to Northwest China (Shaanxi, Gansu, Ningxia, Qinghai, and Xinjiang). Cultivated licorice is found in provinces including Heilongjiang, Jilin, Liaoning, Inner Mongolia, Shanxi, Hebei, Ningxia, Gansu, Qinghai, Shaanxi, and Xinjiang, where it forms a long east-west distribution and narrow north-south distribution. Licorice has various medicinal properties, including tonifying the spleen and qi, clearing heat and detoxifying, resolving phlegm and stopping cough, relieving pain, and harmonizing other medicines. It is used for treating spleen and stomach weakness, fatigue, palpitations, shortness of breath, cough with copious phlegm, abdominal pain, limb spasms, carbuncles, boils, and for mitigating drug toxicity. Known as the “Nine Herbs in Ten Formulas,” licorice is susceptible to diseases such as root rot, leaf spot, rust, brown spot, and powdery mildew, with root rot being particularly severe.
