What are the morphological characteristics of this plant?
Glycyrrhiza inflata has a perennial, woody-based herbaceous habit characterized by erect, unbranched stems that reach heights of up to 1.5 meters. The leaves are pinnately compound, featuring numerous small, oblong leaflets that are arranged oppositely along the rachis. Its distinctive inflated pods are oblong-ellipsoid, often displaying a slightly swollen appearance due to their internal structure. The flowers are typically small, pea-like, and range in color from white to pale violet. These structures are supported by a robust, deep-reaching taproot system that serves as a primary storage organ for the plant.
What is the geographical distribution of this plant?
This plant is native to the southwestern United States and northern Mexico, spanning from southern Utah and Arizona through New Mexico and into Texas. It thrives primarily in arid environments such as desert scrublands, canyons, and rocky slopes. Within these regions, it is frequently found in alkaline soils and well-drained areas typical of the Mojave and Sonoran deserts. Its distribution follows specific elevation gradients where seasonal moisture allows for its biennial growth cycle. This species remains localized to these subtropical and semi-arid western territories.
How is this plant cultivated?
This plant Glycyrrhiza inflata requires well-drained, sandy loam soil and full sunlight to thrive in temperate climates.
Growers must ensure the soil pH remains slightly acidic to neutral for optimal root development. Because it is a perennial legume, it benefits from regular nitrogen fixation but requires consistent moisture during its initial establishment phase. Once mature, the plant is relatively drought-tolerant but performs best when deep-seated moisture is available.
Careful attention to weed control is necessary during the early growing seasons to prevent competition with the developing taproots.
What parts of this plant are used medicinally?
This plant Glycyrrhiza inflata utilizes its hairy roots, leaf, pod, rhizome, and root for various medicinal applications. The rhizome and the primary root contain high concentrations of active compounds used to treat respiratory and digestive issues. Additionally, the hairy roots provide unique therapeutic properties when processed for traditional remedies. The leaf and the pod are also harvested to contribute to the plant's diverse pharmacological profile. Together, these different anatomical structures serve as the foundation for its medicinal value.
According to a study published by "Cells", Glycyrrhiza inflata Batalin is a medicinal licorice species that has been used by humans for centuries. Licochalcone A (LCA) is a characteristic flavonoid that accumulates in the roots of Glycyrrhiza inflata with high economical value. The study found that the HDAC inhibitor nicotinamide (NIC) could enhance the accumulation of LCA and total flavonoids in Glycyrrhiza inflata seedlings. Research using RNAi transgenic hairy roots showed they accumulated much more LCA and total flavonoids than OE lines and the controls. These transgenic hairy roots also demonstrated that the GiLMT1 gene is required for LCA accumulation.

According to a study published by "Planta medica", licochalcone A, which is 3-a,a-dimethylallyl-4,4'-dihydroxy-6-methoxychalcone, was isolated from the root of Glycyrrhiza inflata Beta (Leguminosae). This compound showed anti-inflammatory action towards mouse ear edema induced by arachidonic acid (AA) and 12-O-tetradecanoylphorbol 13-acetate (TPA) through topical application. Anti-tumour promoting action was observed in vivo for mouse skin papilloma initiated by dimethylbenz[a]anthracene (DMBA) and promoted by TPA. Additionally, licochalcone A inhibited in vitro 32Pi-incorporation to phospholipids in HeLa cells promoted by TPA. A competitive interaction of licochalcone A with the TPA-receptors in the cell membrane has been suggested.
The primary pharmacological activities of this plant are shown in the list below.
- anti-inflammatory
- antimicrobial
